HIV symptoms in men are the same as in anyone — the virus doesn’t distinguish by gender. Around 70-80% of people experience a seroconversion illness 2-4 weeks after infection, with symptoms often mistaken for flu. After this, HIV typically has no symptoms for years while silently damaging the immune system. Testing is the only reliable way to know.

Early Symptoms (Seroconversion)
| Symptom | How Common |
|---|---|
| Fever | Very common |
| Sore throat | Common |
| Body rash | Common |
| Swollen lymph nodes | Common |
| Headache | Common |
| Muscle/joint pain | Common |
| Fatigue | Common |
| Mouth ulcers | Moderate |
These appear 2-4 weeks after infection and last 1-2 weeks.
Asymptomatic Phase
After seroconversion, most men have no symptoms for years. The virus quietly damages the immune system. Without testing, infection goes undetected.
Later Symptoms (Advanced HIV)
- Persistent weight loss
- Chronic diarrhoea
- Night sweats
- Recurring infections
- Oral thrush
- Skin problems
When to Test
- After unprotected sex
- New partner
- MSM — every 3 months
- Flu-like illness after possible exposure
- Any symptoms above
Treatment
Modern ART means near-normal life expectancy. Treatment is free on the NHS. Undetectable = untransmittable (U=U).
