Q and A


What is seroconversion and what are the symptoms?


HIV seroconversion is the time in which a person first develops antibodies for HIV. They will not yet test positive on an HIV antibody test.

The word just means that your sero status is converting from being HIV antibody negative to HIV antibody positive.

Seroconversion usually occurs about 10 days after infection, and for mostĀ people it starts 1-3 weeks after infection.

About 80% of people get symptoms but 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. The commonly 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 that can decide your level of risk.

Stress and anxiety can produce similar general symptoms even though they have not caught 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
  • rash
  • headache
  • 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 MAY be considered an indication that you have been infected.

The only way to know if you are HIV positive is by takingĀ 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.

    Thanks for your response dear Lisa. Well, she left for the city only today. I have asked her to report at the HIV care center at the city. I work in a rural community. We don’t have an elaborate HIV Care center here.

    Hi Ipalibo,

    Yes this is possible. Has her HIV doctor said anything?

    A patient received about 5 units of blood between 15th may and 1st June this year, for anaemia secondary to ?heavy menstrual flows. However, because patient was having high grade fevers, we decided to run various tests including tests for HIV & HCV on 7th May. Both tests returned antibody-positive. Is there any chance patient got HIV-infected from the transfusions that were carried out barely 3weeks to this test?

    I had protected sex ( condom was covering hafl of my condom) but penetrated inside the condom. am not sure about vaginal fluid. the person whom i had the sex is unknown status. 27 days later my joints started painbut not that much its recurring pain. I can feel it for 1 minute and it can go away the next minute. I don’t have any other symptoms but Internet searches are telling me muscle and joint pains are common symptom of ARS? is this true or not? and what’s my chance of getting infected using unbroken but half protected condom.???
