The world’s older population continues to grow at an unprecedented rate. Today, 8.5 percent of people worldwide (617 million) are aged 65 and over. According to a new report, “An Aging World: 2015,” this percentage is projected to jump to nearly 17 percent of the world’s population by 2050 (1.6 billion).
“Older people are a rapidly growing proportion of the world’s population,” said NIA Director Richard J. Hodes, M.D. “People are living longer, but that does not necessarily mean that they are living healthier. The increase in our aging population presents many opportunities and also several public health challenges that we need to prepare for. NIA has partnered with Census to provide the best possible data so that we can better understand the course and implications of population aging.”
“An Aging World: 2015” contains detailed information about life expectancy, gender balance, health, mortality, disability, health care systems, labor force participation and retirement, pensions and poverty among older people around the world.
America’s 65-and-over population is projected to nearly double over the next three decades, from 48 million to 88 million by 2050.
“We are seeing population aging in every country in every part of the world,” said John Haaga, Ph.D., acting director of NIA’s Division of Behavioral and Social Research. “Many countries in Europe and Asia are further along in the process, or moving more rapidly, than we are in the United States. Since population aging affects so many aspects of public life — acute and long-term health care needs; pensions, work and retirement; transportation; housing — there is a lot of potential for learning from each other’s experience.”
Highlights of the report include
- America’s 65-and-over population is projected to nearly double over the next three decades, from 48 million to 88 million by 2050.
- By 2050, global life expectancy at birth is projected to increase by almost eight years, climbing from 68.6 years in 2015 to 76.2 years in 2050.
- The global population of the “oldest old” — people aged 80 and older — is expected to more than triple between 2015 and 2050, growing from 126.5 million to 446.6 million. The oldest old population in some Asian and Latin American countries is predicted to quadruple by 2050.
- Among the older population worldwide, noncommunicable diseases are the main health concern. In low-income countries, many in Africa, the older population faces a considerable burden from both noncommunicable and communicable diseases.
- Risk factors — such as tobacco and alcohol use, insufficient consumption of vegetables and fruit, and low levels of physical activity — directly or indirectly contribute to the global burden of disease. Changes in risk factors have been observed, such as a decline in tobacco use in some high-income countries, with the majority of smokers worldwide now living in low- and middle-income countries.
Liberia was declared free of the Ebola virus by global health experts on Thursday, a milestone that signaled an end to an epidemic in West Africa that has killed more than 11,300 people.
But the World Health Organisation (WHO) warned there could still be flare-ups of the disease in the region, which has suffered the world’s deadliest outbreak over the past two years, as survivors can carry the virus for many months and could pass it on.
Health specialists cautioned against complacency, saying the world was still underprepared for any future outbreaks of the disease.
Washington Scored Five Out of 10 on Key Indicators Related to Preventing, Detecting, Diagnosing and Responding to Infectious Disease Outbreaks
A new report finds Washington state scored only 5 out of 10 on key indicators related to preventing, detecting, diagnosing and responding to outbreaks.
The state-by-state analysis was prepared by Trust for America’s Health (TFAH) and the Robert Wood Johnson Foundation (RWJF)
Twenty-eight states and Washington, D.C. scored 5 or lower out of 10 key indicators.
Five states—Delaware, Kentucky, Maine, New York and Virginia—tied for the top score, achieving eight out of 10 indicators. Seven states — Idaho, Kansas, Michigan, Ohio, Oklahoma, Oregon and Utah — tied for the lowest score at three out of 10.
The report, Outbreaks: Protecting Americans from Infectious Diseases, concluded that the United States must redouble efforts to better protect Americans from new infectious disease threats such as MERS-CoV and antibiotic-resistant Superbugs and resurging illnesses like whooping cough, tuberculosis and gonorrhea.

The number of people killed by malaria dropped below half a million in the past year, reflecting vast progress against the mosquito-borne disease in some of the previously hardest-hit areas of sub-Saharan Africa.
The World Health Organization’s annual malaria report showed deaths falling to 438,000 in 2015 – down dramatically from 839,000 in 2000 – and found a significant increase in the number of countries moving toward the elimination of malaria.
Malaria prevention measures – such as bednets and indoor and outdoor spraying – have averted millions of deaths and saved millions of dollars in healthcare costs over the past 14 years in many African countries, the report said.
Before you travel internationally, ensure that you are up to date on all your routine vaccines, as well as travel vaccines.
More and more Americans are travelling internationally each year. Today more than a third of Americans have a passport. It is important to remember that some types of international travel, especially to developing countries and rural areas, have higher health risks.
These risks depend on a number of things including:
- Where you are traveling
- Your activities while traveling
- Your current health status
- Your vaccination history
Measles and International Travel
Each year, unvaccinated people get measles while in other countries and bring it to the United States. This has sometimes led to outbreaks. The majority of measles cases brought into the U.S. come from U.S. residents. When we can identify vaccine status, almost all are unvaccinated.
Vaccination is the best protection against measles. Before leaving for trips abroad, make sure you and your family are protected against measles. Plan ahead and check with your doctor to see if you and your family need MMR (measles-mumps-rubella) vaccine.
It took 15 years and hundreds of millions of vaccines. But North America and South America have officially eradicated rubella, health authorities said Wednesday. Rubella, also known as German measles, is only the third virus eradicated from people in the Western Hemisphere.
The World Health Organization has admitted serious failings in its handling of the Ebola crisis and pledged reforms to enable it to do better next time, its leadership said in a statement seen by Reuters on Sunday.

Poor quality medicines are a real and urgent threat that could undermine decades of successful efforts to combat HIV/AIDS, malaria and tuberculosis, according to the editors of a collection of journal articles published today.
Scientists report up to 41 percent of specimens failed to meet quality standards in global studies of about 17,000 drug samples.
Among the collection is an article describing the discovery of falsified and substandard malaria drugs that caused an estimated 122,350 deaths in African children in 2013. Other studies identified poor quality antibiotics, which may harm health and increase antimicrobial resistance.
However, new methodologies are being developed to detect problem drugs at the point of purchase and show some promise, scientists say. Continue reading

The Ebola virus circulating in humans in West Africa is undergoing relatively few mutations, none of which suggest that it is becoming more severe or transmissible, according to a National Institutes of Health study in the journal Science.
The study compares virus sequencing data from samples taken from patients in Guinea (March 2014), Sierra Leone (June 2014) and Mali (November 2014).
Ebola virus, isolated in November 2014 from patient blood samples obtained in Mali. The virus was isolated on Vero cells in a BSL-4 suite at Rocky Mountain Laboratories.
“The Ebola virus in the ongoing West African outbreak appears to be stable—that is, it does not appear to be mutating more rapidly than viruses in previous Ebola outbreaks, and that is reassuring,” said Anthony S. Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), part of NIH. “We look forward to additional information to validate this finding, because understanding and tracking Ebola virus evolution are critical to ensuring that our scientific and public health response keeps pace.” Continue reading
A crackdown on corruption in the water sector and increasing investment in infrastructure are essential to avoid conflicts over water, “life’s most vital resource”, a United Nations University report said on Tuesday.
Population growth, economic insecurity, corruption and climate change threaten the stability and the very existence of some nations, the report said.
