The period of time between infection with HIV and the production of antibodies is called the window period. The window period for AIDS is about 2-3 weeks, some around 1 week, and long enough to last up to 3 months. However, with the advances in testing technology, the window period for AIDS has been significantly shortened. If the antibody is positive, a confirmatory test will be done. Only if the confirmatory test is positive, the diagnosis of AIDS can be made, because there is a possibility of false positive for the initial antibody screening. Once diagnosed with AIDS, if there is an indication for antiretroviral treatment, you need to go to the local CDC for antiretroviral treatment in a timely manner, and antiretroviral drugs will be distributed free of charge.
