How long does HIV virus remain active in a person's body without manifesting itself?

If a person has had unprotected sex abt 15 yrs ago and he/she has enjoyed good health all these years could he/she still be infected? How long does HIV virus remain dormant in a person's body without manifesting itself? What are the chances that he/she could be infected?

As someone else indicated, although HIV is never dormant, and begins to damage the immune system from the time of infection, symptoms would not show up until a lot of damage has already been done. This may take 2 years, or it may take 6 or more years.

Although it can take years for symptoms to show up, people who have HIV would test positive within 3 to 6 months after getting infected. (More than 98% would test positive within 3 months.)

If you have any reason to believe you may have HIV, you need to get tested.

Great answer, Beetle !

HIV is never dormant, it begins attacking your immune system as soon as a person is infected. However, the time that it takes to reach the point where symptoms of immunodeficiency appear varies. On average a person with untreated HIV will develop AIDS by about a decade later, but sometimes it's just a couple years, and sometimes it's over a decade. If you're concerned about past HIV exposure, get a test.

there is a window period of 3 to 6 months. If u have been tested for HIV and u are negative then it means that u are not infected. get tested for HIV and know ur status so that u can feel safe.

just because you have unprotected sex doesn't mean you have it

The virus can remain dormant for 20 years or even more....
