The World Health Organization (WHO) announced on Wednesday measures to fight the "hidden epidemic" of hepatitis which kills more than one million people a year.

The virus, which settles in the liver causing inflammation, affects 500 million people worldwide but can go unnoticed for years and even decades, the U.N. health agency told reporters in Geneva.

A month long HIV blocker that women could use for protection without their partners knowing? Major new research is beginning in Africa to see whether a special kind of vaginal ring just might work.

Giving women tools to protect themselves when their partners won't use a condom is crucial for battling the AIDS epidemic. Women already make up half of the 34.2 million people worldwide living with HIV, the virus that causes AIDS; even more — 60 percent — in hard-hit Africa are women.

Sunbed users run a 20 percent higher risk than non-users of developing skin cancer, according to a report that blamed some 800 melanoma deaths in Europe every year on indoor tanning.

About 3,400 of some 64,000 new cases of cutaneous melanoma diagnosed in 18 European countries every year are related to sunbed use -- more than five percent, said a statement issued by the BMJ medical journal.

Stella Nayiga clutches her mobile phone as she describes the messages that she received punctually every morning and evening for over a year, reminding her to take her antiretroviral (ARV) drugs regularly.

"The text messages would come twice a day and were saying things like 'Dear friend, please take care of yourself' and when you got them you knew it was time to take your medicine," Nayiga, 28, told Agence France Presse.

The U.N.'s food agency and the OIE called on countries on Monday to comply with a 2011 global moratorium and destroy potentially dangerous rinderpest virus samples or put them into safe storage.

The deadly animal virus, which caused cattle plague, was the second viral disease in history to be wiped out after smallpox more than 30 years ago.

A closely watched experimental Alzheimer's treatment has failed to slow the disease in one late-stage study, a big disappointment for doctors and patients but not the end of the road for the drug. Pfizer Inc. said Monday that it will continue to study its effect on a different group of patients.

Pfizer, which is testing bapineuzumab with partner Johnson & Johnson, said the injected drug didn't slow mental or functional decline in patients with mild or moderate Alzheimer's disease. The study included about 1,100 patients who carry a gene called ApoE4, which gives people a higher risk of developing the memory-robbing disorder.

A Chinese baby drinks coconut milk …

A Chinese dairy has been ordered to suspend production after a cancer-causing toxin was found in its infant formula, China's quality watchdog said Monday, in the country's latest milk scare.

Researchers reported progress Monday with an experimental drug cocktail that killed a record 99 percent of TB bacteria in two weeks and costs a fraction of existing treatments.

It may also, crucially, be compatible with AIDS medicine.

Should all U.S. children get tested for high cholesterol? Doctors are still debating that question months after a government-appointed panel recommended widespread screening that would lead to prescribing medicine for some kids.

Fresh criticism was published online Monday in Pediatrics by researchers at one university who say the guidelines are too aggressive and were influenced by panel members' financial ties to drugmakers.

Using cells from rat hearts and a seer polymer film, scientists on Sunday reported they had created an artificial jellyfish that could one day help save patients with heart disease.

The exploit marks an advance in so-called bio mimicry, in which a natural wonder inspires copycat innovation in the lab.
