Ameena Goga and colleagues describe how five countries in sub-Saharan Africa are monitoring the effectiveness of national programmes to prevent vertical transmission of HIV

Key messages

  • Monitoring vertical transmission of HIV is important in high HIV prevalence low and middle income countries where health systems are often weak or stretched beyond capacity

  • WHO recommends three methods to measure the effectiveness of programmes that prevent vertical transmission of HIV: statistical modelling, surveys or surveillance, and analysis of programme data

  • Kenya, Malawi, South Africa, Uganda, and Zimbabwe all use statistical modelling to monitor programme effectiveness

  • All countries are strengthening routine programmatic monitoring, which requires additional systems such as allocating unique identifiers, and developing interclinic data linkages to trace clients who transfer between facilities

Vertical transmission of HIV can occur during pregnancy, delivery, or through breast feeding. The main driver of vertical transmission is a high maternal viral load.1 Between 2002 and 2016, low and middle income countries (LMICs) in sub-Saharan Africa with high HIV prevalence improved their policies to prevent vertical transmission of HIV. In 2002, national policies recommended single dose nevirapine at the onset of labour, with limited or no breast feeding. By 2016, all Global Plan priority countries in sub-Saharan Africa (where 90% of the world’s HIV positive pregnant women live) had adopted Option B+ with promotion of breast feeding.2 Option B+ was a dramatic policy change recommending lifelong triple antiretroviral therapy (ART) for all pregnant and lactating women living with HIV. The aim is to protect the child from HIV infection, ensure the mother’s future health, and prevent horizontal transmission of HIV.

Monitoring country level effectiveness of these policy changes is critical, both to ensure they are making a difference to people’s lives and to track progress towards achieving global goals. These goals include the Sustainable Development Goal of …
