Birth Outcomes in HIV Both antiretroviral-therapy (ART)-naïve and ART-experienced HIV-infected pregnant women have higher incidences of pre-term birth (PTB) compared to HIV-uninfected women. For example, the global prevalence of PTB is around 8%, while the rates in in HIV-infected populations are...

Highly active antiretroviral therapy (HAART) has reduced morbidity and mortality among HIV-infected persons worldwide. However, early treatment failure (i.e. WHO stage 3 or 4 illnesses or death during the first 24 months of HAART) is more than 3-fold higher in resource limited settings (RLS) than...
