WHO chief scientist Soumya Swaminathan told DW that despite the COVID-19 crisis, countries cannot neglect deadly diseases such as HIV/AIDS, tuberculosis and malaria.
"When you're faced with a shock like this pandemic, very few health systems have been able to cope," she said. "Most health care workers have been diverted and must provide essential health services."
Swaminathan stressed the necessity for governments "to continue to focus on these other diseases," calling them "killers that haven't gone away."
