Acute HIV infection
Also known as: Primary HIV, Acute retroviral syndrome
Acute HIV infection condition guide: symptoms, causes, prevention, and when to seek care. Educational only — not a diagnosis.
Overview
Acute HIV infection occurs in the weeks after exposure. The virus multiplies quickly and a person may have fever, rash, and swollen glands. This stage carries high transmission risk, even when standard tests are still turning positive.
Symptoms
- Fever
- Rash
- Swollen lymph nodes
- Sore throat
- Muscle aches
- Fatigue
- Occasional mouth sores
Causes
It spreads through blood, condomless sex, shared needles, or from parent to child. Not everyone notices acute symptoms.
Treatment (general information)
Start antiretroviral therapy promptly after clinical confirmation. Special tests may be needed early. PEP counselling can help right after a high-risk exposure before infection is confirmed.
Prevention
Condoms, PrEP for people at higher risk, no shared needles, and regular testing. Pregnant people should be tested in antenatal care.
When to see a doctor
Seek care quickly after a high-risk exposure or if you have fever and rash after condomless sex. Ask about PEP within 72 hours.
Frequently asked questions
- Is a standard HIV test enough early on?
- Sometimes not. In the first weeks a special test may be needed. A clinic will advise the right type.
- Is this different from AIDS?
- Yes. This is the earliest HIV stage. AIDS is a later stage without treatment. Antiretrovirals prevent that progression.
