Seroconversion is the time when immune responses to HIV start to develop through the body. This usually occurs within the first two-four weeks after transmission. Up to 80 per cent of people will suffer symptoms which can last a few days or a few weeks.


The most common symptoms are:

  • Fatigue
  • Fever
  • Sore throat
  • Rash
  • Headache
  • Loss of appetite
  • Swollen lymph glands
  • Aching muscles and joints


Having only one or two symptoms is very unlikely to be HIV.
