Hello, good morning. I want to ask. I am still confused about the window period, from the articles I read, the window period lasts for 3 months after risky activities. Well, for example, there is someone who is doing risky activities for a year or two years ago and only did a HIV test last month and showed negative results, meaning he is okay because according to an article that I read the window has passed if for example God forbid him exposed? Please explain, because I’m quite confused and stressed about this. thanks.

Hello Zio


The window period is the gap between the entry of the virus into the body until the formation of antibodies. Everyone has a different window period. There are some people who have a window period of several weeks, some are several months, and in rare cases a window period of several years occurs. The body needs time to recognize the virus, process the virus, and produce antibodies against the virus. That is why antibodies cannot be directly produced.


In the case of HIV, when someone is infected, a viral load period (the level of the virus increases in the blood) in the first 7-14 days. After that, it starts to enter the stage where the p24 antigen (a typical protein of HIV) begins to be detected, usually at week 2-3. By the 4th week about 95% of people infected with HIV will have antibodies. In the 3rd month about more than 99% of people infected with HIV will have antibodies. That is why many articles suggest testing for HIV in the third month, because antibodies to HIV are generally detected.


In fact, with a 4th generation HIV test, the virus can be detected in the second or third week after the risky action. Generally a person will be advised to carry out an HIV test in the early weeks, then repeat it again in the third month. If unsure, the test can be repeated at the sixth month. If the results are always negative, then most likely the person is free from HIV. If you have just taken an HIV test within 2 years of risky action and the results are negative, then you are most likely not to have HIV. If unsure, do the second test 3 months later. A negative result should indicate that you are free of HIV.


Thus my explanation, hopefully broaden your horizons. Regards.
