Viral load and heterosexual transmission of human immunodeficiency virus type 1

Article Abstract:

HIV patients with fewer than 1,500 copies of HIV-1 per milliliter of blood will probably not transmit the virus through sexual intercourse. This was the conclusion of researchers who analyzed transmission rates in 415 couples in which one partner was HIV-positive. Of the 415 HIV-negative partners, 90 became HIV-positive over a 30-month period. The rate of male-to-female transmission was approximately equal to the rate of female-to-male transmission. None of the 51 people with low viral counts transmitted the virus. Increasing levels of virus caused an increasing risk of transmission.

Article Abstract:

Treating HIV-infected pregnant women for a sexually transmitted disease can reduce the rate of neonatal death, premature birth, and low birth weight but does not reduce the risk of transmitting the virus to the baby. This was the conclusion of a study of 2,070 pregnant women in Uganda.
