How long does it take to detect HIV antibodies if infected with AIDS? Clinically, there will be a window period after HIV infection. During this window period, HIV has not yet produced corresponding antibodies, so the antibodies cannot be detected yet, but it is already highly contagious during the window period. If the blood of AIDS patients in the window period is transfused during blood transfusion, they are also very susceptible to HIV infection.

What is the AIDS window period?

Many people may not understand what is the AIDS window period. In fact, it refers to the time when HIV enters the human body, such as the day when unclean sex, blood transfusion and other behaviors that may cause HIV infection occur, and the time when the infection is completely and accurately detected is called the window period.

How long is the AIDS window?

When HIV enters the human body, it will produce viral nucleic acid within 10 days to 4 weeks, the P24 antigen of the virus within 4 weeks, and finally produce antibodies within 3 to 12 weeks. And due to individual differences, such as virus exposure, the response of the individual’s own immune system, etc., the window period is usually 2 weeks to 3 months. , while the current AIDS window period generally recognized by domestic CDCs is 3 months.

However, with the sensitivity of detection reagents, the window period of AIDS is gradually shortened. In recent years, the World Health Organization has clearly pointed out that the window period of AIDS is 14-21 days. Although HIV antibodies cannot be detected during the window period, there is HIV in the body, so the window period is also contagious.

If the HIV antibody test is negative after 3 months, the possibility of AIDS infection can be completely ruled out.

Actually, apart from the window period, AIDS also has an incubation period. Even if a person is infected with AIDS and has HIV antibodies, the patients of Youyou Resource Network will not immediately show symptoms of AIDS. This incubation period can be as short as 6 months to 1 year, usually 8 to 10 years, and up to 20 years. Therefore, if some patients do not undergo HIV antibody testing, they will not know that they are AIDS patients at all, and it is easier for them to infect others, and others will infect others.

Is there no cure for HIV infection?

What many people are most concerned about is whether there will be no cure if they are accidentally infected with HIV, so they can only wait for death. In fact, HIV can be blocked in the early stages of infection. ifIn case of high-risk behavior or known HIV-infected needle-stick injury, HIV-blocking drugs should be taken within 72 hours, preferably within 48 hours and 2 hours. Moreover, the success rate of HIV-blocking drugs reached more than 99% after taking 28 days. So take the blockers early on.

In the hospital, if you have occupational exposure and are accidentally stabbed by an HIV-contaminated needle, you will know that you need to take blocking drugs in time. However, if people are accidentally infected with HIV in society, many people may not know that they can take HIV blocking drugs. They only feel that the world has collapsed, their lives are over, and all that awaits them is death.
