As the love lives of the elderly are extended due to drugs like Viagra, more old people worldwide are contracting HIV, the virus that leads to AIDS, according to a report from the World Health Organization.

The report said the risk factors of people in the over-50 age group have been unexplored until recently, but preliminary data suggests HIV prevalence and incidence in this demographic is higher than expected.

Legislators in the eastern Indonesian province of Papua are poised to pass a law requiring AIDS-infected locals who are sexually active to be implanted with microchips so they can be monitored.

A Papuan lawmaker defended the bill saying a microchip tag or RFID will protect healthy people. "I am a doctor, saving lives is my profession. If we want to save the only limited number of Papuans, we have to take real action because 47 percent of (the country's) HIV/AIDS (cases) are in Papua," Councilor John Manangsang said, according to Asianewsnet.net. There are an estimated 61 AIDS infection for every 100,000 people in Papua, a rate five times higher than the national average of infection.

An American in Germany afflicted with leukemia and AIDS has been cured of the immune system disease after receiving a bone marrow transplant meant to cure his blood disease, his doctor claimed Thursday.

Hematologist Gero Huetter, 39, only identified the patient as a 42-year-old man living in Berlin and being treated at the city's Charité Medical University. The man has been suffering from AIDS for more than 10 years and also has leukemia.

The discovery of a 50-year-old human tissue sample in an African university shows that HIV/AIDS pandemic in humans originated at least three decades earlier than previously thought.

Michael Worobey, an evolutionary biologist at the University of Arizona, Tucson, and lead author of the study suggests that AIDS may have been triggered by rapid urbanization in west-central Africa during the early 20th century and the virus most likely started circulating among humans in sub-Saharan Africa sometime between 1884 and 1924.
