A new report finds that by 2100, there will be more people alive on the planet than has ever previously been predicted. We investigate what the consequences these extra bodies may have for maintaining public health.

The potentially catastrophic consequences of an exponentially growing global population is a favorite subject for writers of dystopian fiction.

The most recent example, Utopia - a forthcoming David Fincher-directed series for HBO - won critical acclaim in its original incarnation on UK television for its depiction of a conspiracy-laden modern world where the real threat to public health is not Ebola or other headline-friendly communicable viruses, but overpopulation.

Fears over the ever-expanding number of human bodies on our planet are not new and have been debated by researchers and policy makers for decades, if not centuries. However, recent research by University of Washington demographer Prof. Adrian Raftery - using modern statistical modeling and the latest data on population, fertility and mortality - has found that previous projections on population growth may have been conservative.

"Our new projections are probabilistic, and we find that there will probably be between 9.6 and 12.3 billion people in 2100," Prof. Raftery told Medical News Today. "This projection is based on a statistical model that uses all available past data on fertility and mortality from all countries in a systematic way, unlike previous projections that were based on expert assumptions."

Prof. Raftery's figure places up to an additional 5 billion people more on the Earth by 2100 than have been previously calculated.

A key finding of the study is that the fertility rate in Africa is declining much more slowly than has been previously estimated, which Prof. Raftery tells us "has major long-term implications for population."

Fertility rates declining more slowly in Africa than previously reported

A 2003 Centers for Disease Control and Prevention (CDC) report found that, in sub-Saharan Africa, both fertility and mortality rates were high, with the proportion of people aged over 65 expected to remain small, increasing from an estimated 2.9% in 2000 to 3.7% in 2030.

The CDC report notes that fertility rates declined in developing countries during the preceding 30 years, following a 20th century trend among developed countries. The pattern established by developed countries - and presumed to follow in developing countries - was that countries shift from high fertility and high mortality rates to low fertility and delayed mortality.

This transition starts with declining infant and childhood mortality as a result of improved public health measures. Improvements in infant and childhood mortality contribute to longer life expectancy and a younger population.

This trend of adults living longer, healthier lives is typically followed by a decline in fertility rates. The CDC report suggested that by 2030, there would be similar proportions of younger and older people in developing countries, by that point mirroring the age distribution in developed countries circa 1990.

Prof. Raftery's research, however, notes that in Nigeria - Africa's most populous country - each woman has an average of six children, and in the last 5 years, the child mortality rate has fallen from 136 per 1,000 live births to 117. This works out as a population increase of 20 people per square mile over the same timespan.

How will population growth affect developing countries?

But what does this mean for countries where the public health system is already stretched to breaking point - as has been demonstrated by the recent Ebola epidemic?

"Rapid population growth is likely to increase the burden on the public health service proportionally," answered Prof. Raftery.

"There are already big public health needs and challenges in high-fertility countries, and rapid population growth will make it even harder to meet them." However, if the fertility rate declines faster, Prof. Raftery suggests that high-fertility countries can reap "a demographic dividend."

He explained:

"This is a period of about a generation during which the number of dependents (children and old people) is small. This frees up resources for public health, education, infrastructure and environmental protection, and can make it easier for the economy to grow. This can happen even while the population is still increasing."

Does this suggest that an increasing population is not quite as much of a threat, but that it is more specifically the accelerations and decelerations in fertility rates that provide warning signs to future public health crises?

"Following a long run of an increasing human population growth rate, over the past half century the rate has been halved from about 2% to about 1%," Darryl Holman, professor of biological anthropology at the University of Washington, explained to MNT.

"The turnaround is quite remarkable," he said. "But as long as the growth rate remains positive, our species will eventually reach numbers and densities where technological solutions cannot ameliorate resource scarcity."

High population density leads to a much higher rate of contact between humans, which means that communicable diseases - ranging from the common cold to Dengue fever - can be much more easily transmitted.

And more people means greater efforts are needed to control waste management and provide clean water. If these needs cannot be adequately met, then diarrheal diseases become much more common, resulting in what Prof. Holman described to the University of Washington's news website The Daily UW as a "huge, huge, huge difference in mortality rates."

Taking a more general view, "the anticipated increase in the number of older persons will have dramatic consequences for public health, the health care financing and delivery systems, informal caregiving, and pension systems," wrote the authors of the CDC's 2003 report.

Overpopulation and the environment

"Can we assume that life on earth as we know it can continue no matter what the environmental conditions?," asked the authors of a 2001 Johns Hopkins School of Public Health report on the health consequences of population growth.

The Johns Hopkins report quoted figures demonstrating that unclean water and poor sanitation kill over 12 million people every year, while air pollution kills 3 million. In 64 of 105 developing countries, population has grown faster than food supplies.

By 2025, the report claimed, humankind could be using over 90% of all available freshwater, leaving just 10% for the world's plants and animals.

Prof. Holman summarizes the writings of experts Joel Cohen, E.O. Wilson, Paul Ehrlich and Ronald Lee, who have argued that the consequences of long-term environmental degradation - "specifically rising sea levels, disruption of agriculture and the increased frequency of extreme weather events resulting from anthropogenic climate change, exacerbated by resource scarcity" - create social problems that lead to social unrest.

With more people living together than ever before, it seems inevitable that this compounded social unrest would lead to increased warfare and fighting for resources.

According to the Johns Hopkins researchers, about half of the world's population currently occupies a coastal strip 200 kilometers wide - which means that 50% of us are squeezed together on just 10% of the world's land surface.

The projected flooding of these coastal regions as a result of global warming and rising sea levels could displace millions of people, result in widespread droughts and disrupt agriculture.

The Johns Hopkins team identified two main courses of action to divert these potential disasters.

Firstly - sustainable development. The report authors argued this should include:

• More efficient use of energy
• Managing cities better
• Phasing out subsidies that encourage waste
• Managing water resources and protecting freshwater sources
• Harvesting forest products rather than destroying forests
• Preserving arable land and increasing food production
• Managing coastal zones and ocean fisheries
• Protecting biodiversity hotspots.

The second vital area of action is the stabilization of population through good-quality family planning, which "would buy time to protect natural resources."

How to reduce fertility in a morally acceptable way?

Commenting on Prof. Raftery's finding that we may be welcoming an additional 5 billion individuals onto the planet by 2100 than had previously been estimated - a potential global population of 12.3 billion people - Prof. Holman admits that "it is difficult to know what the public health effects will be."

He explains:

"By then, we may see severe petroleum and fresh water resource shortages, climate changes that affect agriculture patterns that, in turn, affect food supplies. Reducing fertility in socially and morally acceptable ways seems like one public health strategy to avoid - or at least postpone - testing some of these limits."

In Utopia, a sinister governmental organization proposes to sterilize a large percentage of the population by rolling out a secretly modified vaccine in response to a manufactured flu pandemic. Obviously, that is not a socially or morally acceptable strategy for reducing fertility - but what is?

Experts consider boosting the education of girls in developing countries to be a prime solution.

As well as acquiring more control over their reproductive life, an educated female workforce should have more opportunities of employment and of earning a living wage. Studies report that the children of educated women also have better chances of survival and will become educated themselves. This pattern continuing across generations is associated with a decline in fertility rates.

A 2011 article by the Earth Policy Institute (EPI), analyzing data from the United Nations (UN), states that "countries in which more children are enrolled in school - even at the primary level - tend to have strikingly lower fertility rates."

In particular:

"Female education is especially important. Research consistently shows that women who are empowered through education tend to have fewer children and have them later. If and when they do become mothers, they tend to be healthier and raise healthier children, who then also stay in school longer. They earn more money with which to support their families, and contribute more to their communities' economic growth. Indeed, educating girls can transform whole communities."

The relationship between education, fertility and national poverty is a direct one. As the EPI authors add: "When mortality rates decline quickly but fertility rates fail to follow, countries can find it harder to reduce poverty."

The UN's 2012 Revision of the world population prospects report suggested if we make rapid reductions in family size, then it may still be possible to constrain the global population to 8 billion by 2045.

No projections are set in stone - all are contingent on what extent fertility rates will sway over the next century. And, as Prof. Holman pointed out to us, the nature of the threat posed by overpopulation has "been vigorously debated for over 200 years" with experts still not in complete accord.

For instance, in the 1980s, said Prof. Holman, the economist Julian Simon and ecologist Paul Ehrlich went on tour together, with a series of debates about the consequences of population growth.

"Ehrlich argued that continued population growth would lead to disaster for humans. Simon argued that population growth provided more people to invent new solutions to the problems confronting humans," said Prof. Holman, adding:

"Given the trends to this point, Simon has been 'more right.' One simple measure of this is mortality rates, which have decreased for most human groups. The flaw in Simon's argument may well be that we have never hit the limits of our finite earth. Positive population growth guarantees that we will, someday, hit some hard limits."

"So that," Prof. Holman concluded, "is the long term."

With the Ebola outbreak dominating the national discourse, parents and caregivers are inevitably going to be confronted with the necessity of explaining the deadly and exotic disease to children.

One Connecticut company was already poised to help in that process, and it has seen a dramatic spike in sales as a result.

Giantmicrobes Inc. was founded about a decade ago with the intention of creating stuffed toys based on the actual microscopic images of various microbes as an educational tool for caregivers and young children, said Laura Sullivan, vice president of operations, in an interview with CBS News.

"It started with the common cold and similar things," Sullivan said. "It was marketed to pediatricians and parents initially. The idea is that kids respond favorably to stuffed animals."

The thinking is that children would be better able to understand what is happening in their body if they could see a softer, cuddlier version of it, Sullivan said.

Before long, the company's offerings expanded to a number of different of viruses and diseases, and the audience expanded with it.

About five years ago, the company began offering plush toys whose design was based on the microscopic image of the Ebola virus. Now, they are struggling to keep up with demand, Sullivan said.

While she declined to give specific sales figures for the Ebola plush toys, Sullivan said: "They're selling like hot cakes. We're out of stock again."

They have ramped up production with their Chinese manufacturers and are rushing to feed the demand, Sullivan said.

Their Ebola products - which include regular- and giant-sized plush recreations of the virus, as well a petri dish and something called "Primordial Putty" - are currently only available through the company's website, but much of the rest of their line can be found in everything from hospital gift shops to college bookstores to medical supply stores.

Sullivan said this isn't the first case of a headline-making disease affecting their sales. The swine flu outbreak a few years ago caused a similar spike in sales, but Sullivan added it was not quite at the level of Ebola.

"It's a neat little product," Sullivan said. "In the case of Ebola, it's been a helpful way for families talk about it and take some of the scariness away."

Released on Friday, the survey of 700 Registered Nurses at over 250 hospitals in 31 states included some sobering preliminary results in terms of hospital policies for patients who present with potentially infectious diseases like Ebola.

• 80% say their hospital has not communicated to them any policy regarding potential admission of patients infected by Ebola
• 87% say their hospital has not provided education on Ebola with the ability for the nurses to interact and ask questions
• One-third say their hospital has insufficient supplies of eye protection (face shields or side shields with goggles) and fluid resistant/impermeable gowns
• Nearly 40% say their hospital does not have plans to equip isolation rooms with plastic covered mattresses and pillows and discard all linens after use, less than 10 percent said they were aware their hospital does have such a plan in place
• More than 60% say their hospital fails to reduce the number of patients they must care for to accommodate caring for an “isolation” patient

National Nurses United (NNU) started the survey several weeks ago and released the preliminary results last Friday (here). The NNU has close to 185,000 members in every state and is the largest union of registered nurses in the U.S.

The release of the survey coincided with Friday’s swirling controversy on how the hospital in Dallas mishandled America’s first case of Ebola. The patient ‒ Thomas E. Duncan ‒ was treated and released with antibiotics even though the hospital staff knew of his recent travel from Liberia ‒ now the epicenter of this Ebola outbreak.

On October 2, the hospital tried to lay blame of the mishandled Ebola patient on their electronic health record (EHR) software with this statement.

Protocols were followed by both the physician and the nurses. However, we have identified a flaw in the way the physician and nursing portions of our electronic health records (EHR)interacted in this specific case. In our electronic health records, there are separate physician and nursing workflows. Texas Health Presbyterian Hospital Statement ‒ October 2 (here)

Within 24 hours, the hospital recanted the statement by saying no, in fact, “there was no flaw.”

The larger issue, of course, is just how ready are the more than 5,700 hospitals around the U.S. when it comes to diagnosing and then treating suspected cases of Ebola. Given the scale of the outbreak (a new case has now been reported in Spain ‒ Europe’s first), it’s very likely we’ll see more cases here in the U.S.

As an RN herself ‒ and Director of NNU’s Registered Nurse Response Network ‒ Bonnie Castillo was blunt.

What our surveys show is a reminder that we do not have a national health care system, but a fragmented collection of private healthcare companies each with their own way of responding. As we have been saying for many months, electronic health records systems can, and do, fail. That’s why we must continue to rely on the professional, clinical judgment and expertise of registered nurses and physicians to interact with patients, as well as uniform systems throughout the U.S. that is essential for responding to pandemics, or potential pandemics, like Ebola. Bonnie Castillo, RN ‒ Director of NNU’s Registered Nurse Response Network (press release)

As a part of their Health Alert Network (HAN), the CDC has been sounding the alarm since July ‒ and released guidelines for evaluating U.S. patients suspected of having Ebola through the HAN on August 1 (HAN #364). As a part of alert #364, the CDC was specific on recommending tests “for all persons with onset of fever within 21 days of having a high‒risk exposure.” Recent travel from Liberia in West Africa should have prompted more questioning around potential high-risk exposure ‒ which was, in fact, the case.

As it was, a relative called the CDC directly to question the original treatment of Mr. Duncan given all the circumstances.

“I feared other people might also get infected if he wasn’t taken care of, and so I called them [the CDC] to ask them why is it a patient that might be suspected of this disease was not getting appropriate care.” Josephus Weeks ‒ Nephew of Dallas Ebola patient to NBC News

The CDC has also activated their Emergency Operations Center (EOC).

The EOC brings together scientists from across CDC to analyze, validate, and efficiently exchange information during a public health emergency and connect with emergency response partners. When activated for a response, the EOC can accommodate up to 230 personnel per 8-hour shift to handle situations ranging from local interests to worldwide incidents.

The EOC coordinates the deployment of CDC staff and the procurement and management of all equipment and supplies that CDC responders may need during their deployment.

In addition, the EOC has the ability to rapidly transport life-supporting medications, samples and specimens, and personnel anywhere in the world around the clock within two hours of notification for domestic missions and six hours for international missions.

Imagine a time when a device alerts you to the onset of a disease in your body long before it’s a problem. Or when your disease is diagnosed in Shanghai, based on the medical scan you did in Kenya. This future is far closer that you might think due to rapid advances in connected devices and sensors, big data and the integration of health services. Combined, these innovations are introducing a new era in healthcare and personal well-being.

In only a few years, mobile technologies have spawned tremendous innovation of consumer-level health tools. The emerging solutions are focusing on health conditions over a person’s lifetime and on holistic care. They generate constant insights through analytics and algorithms that identify patterns and behaviours. Social technologies enable better collaboration and interconnected digital propositions that reach out to communities of people with similar conditions, engaging them in ways which were never before possible.

We are starting to get a taste of what the consumerization of healthcare will mean in the future. In two to three years, analysing your personal health data will become commonplace for large parts of the population in many countries. Also, it is very likely that for the first time it will not be the chronically ill but the healthy people who will invest the most in managing their health.

Digitization and consumerization will rattle the healthcare industry. It is already tearing at the very fabric of the traditional healthcare companies and providers. Innovation is not only about just adding a new channel or connecting a product. It is also a complete redesign of business models, adjustment of systems and processes and, most importantly, it calls for changing the culture in companies to reflect the new opportunities – and challenges – presented by the digital world.

To drive true industry transformation, companies need to collaborate and continue to learn from each other. Great strides will be made in alliances, which, for example, will deliver open, cloud-based healthcare platforms that combine customer engagement with leading medical technology, and clinical applications and informatics.

The game will not only be played by the traditional healthcare providers. With consumerization, even companies without healthcare expertise, but with strong consumer engagement and trust, could potentially become healthcare companies. Big multinationals invest incremental budgets in developing new propositions and count on their global user bases or professional networks to gain a foothold in the market.

And in parallel, a raft of start-ups are attempting to transform the worlds of preventive or curative healthcare – in many cases, limited only by their imaginations. For example, we may see virtual reality technology moving from gaming industry to healthcare for improving patients’ rehabilitation after a stroke. Or we may see facial recognition software become common in monitoring and guiding patients’ daily medical routines.

While these new propositions tackle a number of healthcare industry’s core concerns and provide solutions to completely new areas, these propositions still need to mature. They need to become scalable, reliable, open, and the user experience needs to be harmonized.

But perhaps one of the most important challenges is related to people’s behaviour and preferences. Regardless of whether these new and existing companies are analysing health data, using virtual reality or reading people’s vital signs, they all need ample time to become trusted and accepted in the emerging digital health care space. Especially for the new entrants, obtaining the right level of credibility will be one of the key success factors.

Consumers, patients and professionals alike, will need the right motivation, reassurance and mindsets to adopt these new solutions. The companies that know how to offer us tailored, cutting-edge solutions, combined with meaningful advice and trustworthiness, will be the winners and become our trusted advisers in health.

Mary Lou doesn't know that she's being tracked.

The 77-year-old is in the middle stages of Alzheimer's and though she lives on her own, her family keeps close tabs on her. If she leaves her Washington D.C. home between 9 p.m. and 6 a.m., a silent sensor on her front door texts her daughter an alert.

There is a sensor on each of Mary Lou's two key chains that detects when she goes outside her condo's grounds. A motion sensor in the kitchen helps monitor her eating habits, and another in the bedroom notes when she wakes up in the morning and catches any sleeping issues. There is even a flood sensor in the laundry room.

All the sensors are made by SmartThings and relay the information back to a small wireless hub. Her two daughters, who act as her caretakers, can monitor it all on a smartphone app and set up special notifications.

"It's kept her to the point where we haven't even had to have in-home care yet. Our goal is to keep her in her home for as long as possible," said her daughter Cathy Johnson.

Caregivers like Johnson are increasingly turning to smart-home technology and wearable devices to monitor family members with Alzheimer's and dementia, helping them live independently longer. One of the first things Alzheimer's patients lose is the ability to learn new things. It makes getting their bearings and adjusting to a new residence especially difficult. But living alone can pose its own dangers, such as leaving a stove on, wandering off or forgetting to take medication.

"Often, decisions about care are made when safety becomes an issue" said said Beth Kallmyer, vice president of constituent services for the Alzheimer's Association. Tools like these sensors "can allow people to feel more comfortable" and ease the transition.

Finding the right system

SmartThings is a DIY home automation system that connects sensors and smart devices with a wireless hub. In addition to sensors like those in Mary Lou's home, the system can loop in smart thermostats, smart plugs, door locks and surveillance cameras.

SmartThings is highly customizable and works easily with third-party sensors, which makes it appealing to people like Cathy Johnson. It also doesn't require a monthly fee, unlike many other systems. (Samsung recently purchased the company for $200 million.)

The elder care tech industry is still young, but Laurie Orlov, an industry analyst, predicts it could be a $20 billion business by 2020. This means that both startups and big-name brands are getting in on the action.

Lowe's, Home Depot, Best Buy, AT&T and Staples all have their own connected home systems and sell starter kits that you can expand by purchasing sensors à la carte.

Systems Lively and BeClose offer senior-specific accessories such as bed, toilet and pillbox sensors. GrandCare offers connected blood pressure, weight and glucose monitoring devices.

Wearable devices can also track health and behaviors, and built-in accelerometers can pick up on physical changes or tell when a wearer has fallen. Tempo is a wristband for seniors that picks up on lapses in routine or changes in gait that might indicate mental or physical deterioration. The device is due out this winter.

"Pet doors, water heaters, you name it we've either got it connected right now or we're in the process of connecting it," said Kevin Meagher, the vice president and general manager of Lowe's smart-home system, IRIS.

Watching without invading privacy

With any device that collects data, privacy can become an issue.

"We want to respect people's autonomy, respect their desire for how they want their care to go. One of the reasons we think people should get diagnosed early is so they can be a part of the conversation," said Kallmyer.

Phil D'Eramo chose to tell his parents about the Lively system he set up in their senior housing. He uses sensors to make sure they take their pills and tracks how many times his father goes to the bathroom at night, information that gets passed on to his doctor. His father, who has Alzheimer's, said it makes him feel more comfortable to know his son is monitoring him.

It helps that Lively includes a social element that appeals to seniors. Caregivers can upload photos, texts and notes to the Lively app from their phones, and once a month Lively will print out and mail the messages and photos to the seniors in a bright orange envelope.

"I compare it to the analog version of Facebook for seniors," said D'Eramo. "It helps them be connected to the digital social world."

The future of memory care

Connected home and wearable technology isn't enough to replace professional care or personal attention from family members. However, it can extend the amount of time a person is able to live independently, and the technology is constantly improving.

"We're just touching the surface of the technology," said D'Eramo. "I think in the future, the Lively base unit could interact with the person, almost like an electronic caregiver."

 (CNN) -- Chikungunya -- a tropical disease with a funny name that packs a wallop like having your bones crushed -- has finally taken up residence in the United States.

Ever since the first local transmission of chikungunya was reported in the Americas late last year, health officials have been bracing for the arrival of the debilitating, mosquito-borne virus in the United States. Just seven months after the first cases were found in the Caribbean, the Centers for Disease Control and Preventionreported the first locally acquired case of chikungunya in Florida.

Even though chikungunya is not on the National Notifiable Diseases Surveillance System list, 31 states and two U.S. territories have reported cases of the disease since the beginning of the year. But only Puerto Rico and the U.S. Virgin Islands reported locally acquired cases. All the other cases were travelers who were infected in countries where the virus was endemic and were diagnosed upon returning to the United States.

That ended Thursday, when the CDC reported a man in Florida, who had not recently traveled outside the country, came down with the illness.

As of right now, the Florida Department of Health confirmed there are at least two cases. One case is in Miami Dade County and the other is in Palm Beach County.

Its arrival did not surprise the chair of the Florida Keys Mosquito Control Board.

"It was just a matter of when. We are prepared in the Keys and have been prepared for some time to deal with chikungunya," Steve Smith said. "From what I am seeing, I'm sure there are more cases out there that we don't know about. It's really a matter of time."

The CDC is working closely with the Florida Department of Health to investigate how the patient came down with the virus. The CDC will also monitor for additional locally acquired U.S. cases in the coming weeks and months.

The virus, which can cause joint pain and arthritis-like symptoms, has been on the U.S. public health radar for some time.

Usually about 25 to 28 infected travelers bring it to the United States each year. But this new case represents the first time that mosquitoes themselves are thought to have transferred the disease within the continental United States

"The arrival of chikungunya virus, first in the tropical Americas and now in the United States, underscores the risks posed by this and other exotic pathogens," said Roger Nasci, chief of CDC's Arboviral Diseases Branch. "This emphasizes the importance of CDC's health security initiatives designed to maintain effective surveillance networks, diagnostic laboratories and mosquito control programs both in the United States and around the world."

The virus is not deadly, but it can be extremely painful, with symptoms lasting for weeks. Those with weak immune systems, such as the elderly, are more likely to suffer from the virus' side effects than those who are healthier. About 60% to 90% of those infected will have symptoms, says Nasci. People infected with chikungunya will often have severe joint pain, particularly in their hands and feet, and can also quickly get very high fevers.

The good news, said Dr. William Schaffner, an infectious diseases expert with Vanderbilt University in Nashville, is that the United States is more sophisticated when it comes to controlling mosquitoes than many other nations and should be able to keep the problem under control.

"We live in a largely air-conditioned environment, and we have a lot of screening (window screens, porch screens)," Shaffner said. "So we can separate the humans from the mosquito population, but we cannot be completely be isolated."

Mosquito-borne virus worries CDC

Chikungunya was originally identified in East Africa in the 1950s. Then about 10 years ago, chikungunya spread to the Indian Ocean and India, and a few years later an outbreak in northern Italy sickened about 200 people. Now at least 74 countries plus the United States are reporting local transmission of the virus.

The ecological makeup of the United States supports the spread of an illness such as this, especially in the tropical areas of Florida and other Southern states, according to the CDC.

The other concern is the type of mosquito that carries the illness.

Unlike most mosquitoes that breed and prosper outside from dusk to dawn, the chikungunya virus is most often spread to people byAedes aegypti and Aedes albopictus mosquitoes, which are most active during the day, which makes it difficult to use the same chemical mosquito control measures.

These are the same mosquitoes that transmit the virus that causes dengue fever. The disease is transmitted from mosquito to human, human to mosquito and so forth. A female mosquito of this type lives three to four weeks and can bite someone every three to four days.

Shaffner and other health experts recommend people remember the mosquito-control basics:

-- Use bug spray if you are going out, especially in tropical or wooded areas near water.

-- Get rid of standing water in empty plastic pools, flower pots, pet dishes and gutters to eliminate mosquito breeding grounds.

-- Wear long sleeves and pants.

Three more people in Colorado have been diagnosed with the plague after coming in contact with an infected dog whose owner contracted a life-threatening form of the disease, state health officials said on Friday.

In all, four people were infected with the disease from the same source, the Colorado Department of Public Health and Environment said in a statement.

Last week the department said a man in an eastern Colorado county whose dog died of the plague had been diagnosed with pneumonic plague, a rare and serious form of the disease.

The man remains hospitalized, but authorities have not released his condition.

The three people in the latest reported cases had "mild symptoms" and have fully recovered after being treated with antibiotics, the department said, adding that they are no longer contagious.

Two of the patients in the new cases contracted pneumonic plague, the department said.

Pneumonic plague is the only form of the disease that can be transmitted person-to-person, usually through infectious droplets from coughing.

The bacteria that causes plague occurs naturally in the western United States, primarily in California, New Mexico, Arizona and Colorado, according to the U.S. Centers for Disease Control and Prevention.

The infected canine in Colorado likely contracted the disease from prairie dogs or rabbits, which are the primary hosts for fleas that carry the bacteria.

When an infected animal dies, the fleas spread the disease when they find another host.

Colorado has seen a total of 12 cases of humans infected with the plague over the last decade, said Jennifer House, the department's public health veterinarian.

"We usually don't see an outbreak like this related to the same source," House said.

Colorado had not had a confirmed human case of pneumonic plague since 2004, she said.

Article from http://diversityinc.com

A new study by the Kaiser Family Foundation finds that in almost every state men of color continue to fare worse than white men on a variety of measures of health, healthcare access and other social determinants of health.

The report, Putting Men’s Health Care Disparities On The Map: Examining Racial and Ethnic Disparities at the State Level, documents thepersistence of disparities between white men and men of color—and among different groups within men of color—on 22 indicators of health and well-being, including rates of diseases such as AIDS, cancer, heart disease and diabetes, as well as insurance coverage and health screenings. It also documents disparities in factors that influence health and access to care such as income and education.

This new analysis provides state-level data for men of many racial and ethnic populations that have not been available before. Among the findings:

• American Indian and Alaska native men had higher rates of health and access problems than men in other racial and ethnic groups on nearly all health indicators. They also had the highest poverty rate and second worst educational attainment, unemployment rate and incarceration rate.
• More than four in 10 Latino men lacked insurance (46 percent) and a personal health care provider (49 percent), and more than a fifth (22 percent) had no doctor visit in the previous year due to cost. Latino men also had the lowest median household income, the largest wage gap compared to white men and the lowest educational status.
• Black men had much higher rates of poverty and incarceration and lower rates of high school graduation than whites. The most striking health disparity was that nationally Black men were more than seven times as likely as white men to be newly diagnosed with AIDS, with a rate of 101.5 new AIDS cases per 100,000 Blacks ages 13 and older compared with 13.5 new cases per 100,000 whites. The disparity was even larger in some states, such as Nebraska,Pennsylvania, and Maryland, where the rate of new AIDS cases was more than 10 times as high among black men compared to whites.
• Nationally, Asian American, Native Hawaiian and Pacific Islander men had the lowest rate of health problems and the fewest barriers to access of all subgroups of men, even white men.
• While white men fared better than minority men on most access and social indicators, they had higher rates of some health problems than men of color, such as higher rates of smoking and binge drinking. For example, in Wisconsin35 percent of white men reported binge drinking compared with 20 percent of minority men.
• Some of the states with the greatest access disparities between white and minority men included Connecticut, Maine, New Jersey, Rhode Island and Washington, D.C., all of which also exhibited some of the greatest disparities in income between white and minority men. Several states with relatively large Native American populations—Arizona,North Dakota and South Dakota—also had large disparities in access between white and minority men.
