With an estimated 25.7 million people living with HIV in Sub-saharan Africa (WHO, 2017) managing and controlling the epidemic is a critical public health issue that has substantial social and economic impact. The UNAIDS target for 90-90-90 by 2020 is an ambitious global treatment target to help end the HIV epidemic. 2017 estimates indicate 81% people with HIV+ people in Eastern and Southern Africa know their status, 66% have access to antiretroviral therapy and 52% of those on treatment are virally suppressed. Better data is required to track and inform progress towards these targets. Jembi is working to improve data collection, data management and data analysis at various levels of health systems.
