What are HIV-related lung infections?

Pneumocystitis pneumonia (PCP) most common (but declining by prophylaxis). Bacterial mostly, TB (at least 1/3 of cases of HIV), 5.5-29% of HIV pt get pneumonia (compared to 0.7-10% in non HIV pt) Viral (CMV), fungi and parasites As CD4 declines ->more incidence of infection (highest risk in IV use, smoker, developing countries and city inhabitant)
