Does delayed acute HIV symptoms extend the window period?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

Is the window period for HIV (Human Immunodeficiency Virus) more extended when the symptoms of acute infection take a long time to show? I was tested for HIV by rapid test at 10 and 15 weeks after exposure (both negative), but I had symptoms by week nine, and worse symptoms by the 13th week.

Can I be calm with these results?

Hello,

Welcome to icliniq.com.

The symptoms of acute HIV infection appear relatively quickly and resolve within a few days. These can appear anywhere between two and six weeks. Your signs at nine weeks could be a coincidental finding, and there could be numerous causes for the symptoms. The tests performed these days for HIV are highly sensitive and specific, and give accurate results. The majority of the people who are infected with HIV develop antibodies within two to eight weeks.

The literature says approximately​ 5 percent develop by three months. With your negative HIV rapid test at 10 and 15 weeks after exposure, you can surely relax and be calm. However, there are recommendations, and I also suggest to my patients to repeat the HIV test at six months of high-risk exposure.

I hope your query is answered, but if you still have any other questions, please revert.

Kind regards.
