"Among people with HIV in Latin America, those diagnosed with tuberculosis (TB) at an initial clinic visit were about twice as likely to die within 10 years as people not initially diagnosed with TB, according to findings from a large observational study. This increased risk persisted despite the availability of TB treatment and mirrored patterns seen previously in HIV-negative populations, according to research supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Research led by Vanderbilt investigators found nearly 40% of HIV-exposed infants in low‐ and middle‐income countries (LMIC) were not in care at 18 months of age or had died. Despite the availability and progress of HIV prevention of mother-to-child transmission (PMTCT) programs which includes postpartum follow-up of HIV-positive mothers and their HIV-exposed infants, many infants do not remain engaged in early infant diagnosis (EID) services that are essential to optimal health outcomes.

Programs and interventions focused on reducing the risk of HIV and early pregnancy, improving school attendance, and empowering girls can have significant and powerful effects for adolescent girls. Simultaneously, these programs may have unanticipated effects that inhibit the program's success.

In 2017, according to UNAIDS, more than 90% of HIV-positive pregnant women accessed antiretroviral (ART) medicines to prevent mother-to child transmission of HIV in Southern Africa, and recent research suggests access and adherence to ART remains high during pregnancy due in part to the scale up of national antenatal (ANC) and ART care clinics. 
 
 Engagement in HIV care after delivery, however, can be challenging.

Researchers in the Vanderbilt Institute for Global Health are testing whether a unique “couples-centered” intervention developed in the southern African nation of Mozambique can reduce mother-to-child transmission of HIV.
