Authorities in Canada said Tuesday they put two poultry farms in British Columbia under quarantine after they tested positive for bird flu.

"Preliminary testing by the province of British Columbia has confirmed the presence of H5 avian influenza on two farms in the Fraser Valley" region of the province, said a statement released by the Canadian Food Inspection Agency (CFIA).

The World Health Organization introduced new cervical cancer guidelines Wednesday, making it easier and cheaper to protect women against one of the deadliest, but most preventable, diseases.

An estimated 270,000 people die each year from the cancer, of which 85 percent are in the developing world where many have limited access to healthcare and struggle to afford the vaccine.

An independent investigation into the deaths of 13 women in India after mass sterilization surgeries found the doctor and his staff used the same needles for all of the procedures and never changed their gloves.

The women died after being paid to have the surgery at a state-run camp in Chhattisgarh state last month, which also left dozens in hospital and sparked widespread criticism of India's family planning program.

An experimental vaccine against the deadly Ebola virus has provoked only mild side effects in volunteers in Switzerland, a Geneva hospital said Tuesday.

"To date, no major side effects have been observed after the injections," the Geneva University Hospital (HUG) said in a statement.

The questions teenagers ask about HIV are brutally honest, anonymous -- and sent in 160 characters or less over mobile phone text messages.

At U-Report, a Zambian HIV advice organisation, thousands of bite-sized questions come through every day.

Faced with an outbreak which has killed almost 1,500 people, Sierra Leone is relying heavily on investigators to hunt down Ebola wherever it breaks out, stopping it in its tracks before it can spread.

Victims have barely been carried off before the questions begin: "How many people live here? Have you traveled recently or attended funerals?"

Too many U.S. infants sleep with blankets, pillows or other unsafe bedding that may lead to suffocation or sudden infant death syndrome, despite guidelines recommending against the practice. That's according to researchers who say 17 years of national data show parents need to be better informed.

THE STUDY

Two months ago, the World Health Organization launched an ambitious plan to stop the deadly Ebola outbreak in West Africa, aiming to isolate 70 percent of the sick and safely bury 70 percent of the victims in the three hardest-hit countries — Guinea, Liberia and Sierra Leone — by December 1.

Only Guinea is on track to meet the December 1 goal, according to an update from WHO.

The World Health Organization issued a call to action to China Monday over HIV/AIDS as government figures said nearly half a million people are living with the disease or its precursor, with hundreds of thousands more thought to be undiagnosed.

Bernhard Schwartlaender, the World Health Organization's representative in China, wrote in an op-ed in the state-run China Daily newspaper that "there is much more China needs to do" to prevent infection and better help those living with HIV.

When Islamic State group fighters swept into northern Iraq's second city Mosul in a lightning June offensive, their propaganda trumpeted a better life for the people under jihadist rule.

Now, nearly six months later, residents there are suffering from a lack of clean water and also a shortage of medicine to treat illnesses caused by it.
