More than 500,000 could die if the delivery of healthcare to HIV victims is disrupted during pandemic.
In 2018 an estimated 470,000 people died of AIDS-related diseases in sub-Saharan Africa.
Modelling held for UN agencies said a 6-month interruption in HIV healthcare services could turn the clock back to 2008, when more than 950,000 AIDS-related deaths were recorded in the region.
Interrupted services could also reverse improvements made in preventing mother-to-child transmission of HIV.
HIV infections among children in sub-Saharan Africa have declined by 43 percent from 250,000 in 2010 to 140,000 in 2018.
Limitation of HIV services for mothers and their children could see new HIV child infections rise by as much as 37 percent in Mozambique, 78 percent in Malawi and Zimbabwe, and 104 percent in Uganda.
