New HIV infections with virus resistant to HIV drugs could rise significantly in San Francisco.


The number of new HIV infections with virus resistant to HIV drugs could rise significantly in San Francisco and become a self-sustaining epidemic, according to a study published in the journal Science and reported by Bloomberg News. The authors also fear that an upswing in transmitted drug-resistant virus could imperil efforts to test and treat nearly everyone living with HIV in developing countries. Transmitted drug resistance (TDR) is an ever-present concern for scientists, physicians and people with HIV. When people with drug-resistant HIV pass their virus to others, those newly infected people have fewer treatment options. About 13 percent of people newly infected with HIV in San Francisco get drug-resistant strains.

According to the World Health Organization, about 33.4 million people were infected with the AIDS- causing virus worldwide as of the end of 2008, making it the world’s most prevalent infectious disease. More than 4 million people in low- and middle-income nations were receiving treatment as of the end of 2008, a 10-fold increase over five years.
