Researchers in France have found a new strain of the virus the causes AIDS.
In a report in the journal Nature Medicine, the researchers identify the patient as a 62-year-old woman from the African nation of Cameroon who tested positive five years ago.
They say the strain she has differs from the three known strains of human immunodeficiency virus and appears to be closely related to a form of simian virus recently discovered in wild gorillas.
The researchers say the finding "highlights the continuing need" for experts to keep a close watch for new HIV variants, particularly in western central Africa.
The three previously known HIV strains are related to the simian virus that occurs in chimpanzees.
The researchers say the most likely explanation for the new find is gorilla-to-human transmission. The woman is said to have had no contact with apes or bush meat, and the researchers say the strain could be circulating unnoticed in Cameroon or elsewhere.
U.S. Health and Human Services Secretary Kathleen Sebelius reiterated Tuesday that she won’t intervene in the “incredibly agonizing” case involving a 10-year-old Pennsylvania girl who is waiting for a lung transplant, telling members of Congress that medical experts should make those decisions.
One of the first provisions of the 2010 health reform law has had its intended effect: shifting costs from hospitals, taxpayers and families to health insurance companies, researchers reported on Thursday. It’s one of the most popular aspects of the law.
People may realize that fast food isn’t health food, but they don’t realize just how fattening it really is, researchers report. They surveyed people eating at 10 burger, chicken, sandwich and doughnut chains and found they greatly underestimated just how much they were chowing down.
A new line of caffeinated chewing gum is causing jitters among health advocates and prompting federal officials to take a new look at the proliferation of jolt-infused foods, including those marketed to children and teens.
