New study gives hope of eliminating mother-to-baby transmission of HIV

Anti-retroviral drugs are a vital tool in the prevention and treatment of HIV. A new study of pregnant women in Tanzania shows that life-long antiviral treatment also seems to prevent viral transmission from mother to baby. The results of the study, which was conducted in part by researchers at Karolinska Institutet in Sweden and published in Lancet HIV, make a promising contribution to the WHO's work with HIV prevention in low and middle-income countries.
