Tuberculosis, HIV and malaria are three of the world's most dangerous infectious diseases, killing 2.4 million people annually. Tuberculosis itself accounts for 1.5 million deaths each year. The main victims are people in parts of Africa and Asia.

The number of people dying from these diseases has fallen sharply for several years. But now the corona pandemic threatens many of the progress that has been made.

- We are starting to see signs of interruptions that are becoming more and more long-lasting and that worries us. If that happened, it would increase the death toll and take us back to the same levels as in 2008, says Tim Martineau, Deputy CEO, Unaids.

The corona pandemic has caused major problems in obtaining medicines, and in several countries people have avoided visiting healthcare clinics for fear of being infected with the corona virus.

According to a model developed by Unaids, a six-month disruption in sub-Saharan Africa could lead to another 500,000 AIDS-related deaths.
