What is seroconversion and what are the symptoms?
HIV seroconversion is a very early stage of HIV infection. It is the time when a person first develops antibodies for HIV.
At this point an HIV antibody test will still be negative. The word just means that your sero status is converting from being HIV antibody negative to HIV antibody positive.
Seroconversion usually occurs starts 1-3 weeks after infection, with average time being around 10 days. Although 4 in 5 people (80%) get symptoms, 1 in 5 (20%) do not.
The symptoms of HIV seroconversion resemble those of a heavy cold or flu.
They commonly involve multiple symptoms that all occur at the same time. They last about a week and then resolve. If you get this heavy response and recently had a risk, it is more important to contact a doctor or clinic. This can decide your level of risk and the best time to test.
However, lots of people get some of these symptoms and it does not mean they are HIV positive. Stress and anxiety can produce similar general symptoms even though without HIV. This includes tiredness from not sleeping, anxiety and worry.
The most common HIV seroconversion symptoms include a combination of several of the following:
- Fatigue (tiredness).
- Fever (high temperature).
- Sore throat.
- Loss of appetite.
- Aching muscles and joints.
- Swollen lymph glands.
Seroconversion involves several symptoms that all start at the same time. Only having one or two of these symptoms is unlikely to be HIV.
These symptoms are not a reliable way of diagnosing HIV infection.
Firstly, 20% of people who become infected with HIV have no symptoms. Secondly, none of the symptoms listed above, on their own, are an indication of HIV.
However, if you get several of these symptoms at the same time AND you have had a recent risk of exposure to HIV, then this MIGHT be an indication of infection.
The only way to know if you are HIV positive is by taking an HIV test. More information on tests is at this link.
If you have recently been exposed to HIV, or think you may have been exposed to HIV, then contact a doctor or sexual health clinic to talk about whether testing for HIV is appropriate.
