 Fungal infections
Candida commonly causes mucocutaneous manifestations in HIV, such as thrush, esophagitis, and vaginitis. Mucocutaneous candidiasis rarely becomes invasive and does not need primary prophylaxis.

Prophylaxis with fluconazole does decrease the incidence of invasive fungal disease, particularly cryptococcocis. Invasive disease occurs primarily at CD4 counts below 75 cells/mm3.

Primary prophylaxis is not recommended because the two-year incidence of invasive disease with these fungi (cryptococcosis, histoplasmosis, coccidioidomycosis) is relatively low (<10%), the medication is expensive, and therapy can select out resistant infection with Candida species and torulopsis yeasts. There is a standard recommendation for secondary prophylaxis, or maintenance therapy, once a patient has had invasive fungal disease.
