Diagnosis
Because HIV does not always cause symptoms, and when the cause may be similar to those of other diseases, it is extremely important to get tested to prevent those who have recently been infected infect others.
The virus is diagnosed by a blood test that detects the presence of HIV-specific antibodies (proteins that react against the disease). As in some cases, once contracted the infection, it may take up to six months before a number of antibodies is high enough to be detected in a normal blood test, it is important to consult your physician about the need for additional tests.

Treatment
When AIDS emerged in the U.S, there was no medicine to combat the underlying immune deficiency and there were few treatments for diseases that are contracted as a result of the virus. NIAID researchers, among others, have managed to develop effective drugs to attack both HIV infections and different kinds of cancer that generate.
These treatments, along with early detection, have managed to extend the life expectancy of patients and significantly improve their quality of life. As a result, in recent years there has been a drastic reduction in the number of AIDS deaths in the United States. follow more health blog such as the health benefits of green tea.
