Seksueel contact geraken door dat de moeder positief is (borstvoeding
Bloedtransfusies of door bevalling)
Overdracht van bloed
Moeilijk om vaccin te ontwikkelen en ontstaan van resistentie door frequente mutaties in RNA virus
=> RNA is heel gevoelig aan transcriptiefouten
Mogelijkheid op dubbele infecties
HAART = highly active anti-retroviral therapy; meerdere virostatica tegelijk toedienen
Eerste fase => klassieke virale infectie
Antistoffen tegen Hiv na 6 weken
Latere fasen => vermagering, tekens immunosuppressie; antistoffen zijn positief en de CD4
count is laag
