Primary infection phase
Happens weeks after exposure
Many asymptomatic
Symptoms: low fever, fatigue, sore throat, malagia, night sweats, go problem, maculopapular rash, headache

Latency phase
No symptoms or sign of illness
Median time is 10 years
Lymphadenopathy develops in some (chronically swollen lymph gland)
15
Phase 3
Without antiretroviral therapy death occurs
Determined by number of cd4 cells

May be indication of hidden lifestyle
Feeling of fear guilt isolation etc
Previous mental health issues
34
Prevention
Risk free or low risk behaviors
