front 1 Origins of HIV and pre-1981 "silent" spread | back 1
1 early challenge - determine whom infants were being infect by. source turned out to be mother
once determined that babies were infected by mothers -> became important to determine the HIV status of the mother
before ARVS, chance of untreated HIV mother to transmit virus to infant = 20-30% Challenges to determine whether AZT could reduce mother-infant HIV transmission:
if mother treated, decrease probability of infection to baby
exposure - being exposed to virions (birth, sex, needle use, etc.)
