A modelling group convened by the World Health Organization and UNAIDS has estimated that if efforts are not made to mitigate and overcome interruptions in health services and supplies during the COVID-19 pandemic, a six-month disruption of antiretroviral therapy could lead to more than 500 000 extra deaths from AIDS-related illnesses, including from tuberculosis, in sub-Saharan Africa in 2020–2021. In 2018, an estimated 470 000 people died of AIDS-related deaths in the region.
