By studying more than 1,700 couples with a partner with AIDS was found to make use of antiretroviral drugs at the beginning of the outbreak decreases by 96% transmissions.
According to the American National Institute of Health to take antiretroviral drugs soon after AIDS was diagnosed allows the interruption of transmission of the disease by blocking infection in about 96% of cases. This finding led the research team to halt four years before the research study involving 1,763 couples for 97% of heterosexuals and other countries around the world, divided into two groups: one where antivirals were administered as soon as the disease is diagnosed, the other has followed the traditional care to recruit only when the immune system starts to drop.
The transmission to the partner took place only once in 881 pairs of the first group and 27 times among the 882 pairs of the second, taking these drugs in a preventive manner, decreases the amount of virus in the blood making the person less infectious.
The discovery thus seems to be the key to the cure for AIDS, pending developed the vaccine, explains Andrew McMichael of the Oxford University, got high expectations for researchers, as announced in Nature: the vaccine SIV, HIV monkeys, macaques defeated the disease in thirteen hours a day.
There are currently several studies on the development of vaccines or new therapies: new vaccine effective in one third of the cases studied (data published in the Lancet), a new cocktail of drugs that would reduce by 44% from male to male transmission (New England Journal of Medicine).
The Director of the National Institute of Infectious Diseases, Anthony Fauci said: “The results of our study reveal that the care of a single sick person can have significant effects on the reduction of disease.”
