HIV develops in several stages, each with different characteristics. Recognising HIV symptoms is crucial for early diagnosis and treatment.
Stage 1: acute HIV infection
Within 1 to 6 weeks after infection with HIV, flu-like symptoms may occur while the body fights the virus. This stage is known as acute HIV infection. Symptoms may include:
- Fever, sore throat, muscle pain and tiredness
- Swollen lymph nodes
- Skin rash
- Diarrhoea
- Night sweats
Some people may have an acute HIV infection without any symptoms. The symptoms of an acute HIV infection can last anywhere from a few days to several weeks.
Stage 2: chronic HIV infection
After the acute stage, the virus is still present in the body but it may not cause any symptoms. This stage can last several years. It is still possible to transmit HIV to others during this stage.
Stage 3: AIDS
Untreated, HIV most often turns into AIDS. This means the immune system is severely damaged, leading to symptoms such as:
- Weight loss
- Chronic fatigue
- Recurrent infections, such as pneumonia or candidiasis
