The other pandemic that we must cure

As the world rightly focuses on Covid-19, on Tuesday's World AIDS Day we should remember that another pandemic resulted from the spread of a virus from animals to humans. HIV has infected more than 77 million people worldwide and, despite significant progress in treatments, has killed over 35 million people -- including 690,000 last year alone. Two-thirds of all new infections and deaths occur in Africa. Now, UNAIDS estimates that the Covid-19 pandemic may set back progress on HIV by a decade.
