Ruptured Membranes and Perinatal HIV Transmission Risk

A prospective study showed that perinatal HIV transmission rates were slightly higher in women who had ruptured membranes for four hours or more (1.9% versus 1% in women with less than 4 hours of rupture). Of the women in the cohort with viral loads less than 1000 copies/mL at delivery, there were no cases of perinatal transmission where membranes had been ruptured up to 25 hours.
