The future of Zambia’s health in the COVID-19 pandemic is keeping Duncan Chanda awake at night. The ‘big three’ diseases worrying him are polio, which has been nearly eradicated in Zambia, measles and AIDS. The human immunodeficiency virus (HIV) clinic he runs at the University Teaching Hospital in Lusaka is closed, and his hospital has suspended the program that ensures every patient who passes through gets screened and tested for HIV. “About 15% of contacts are positive,” he says. Over 100 million children will miss their measles shots this year, according to UNICEF. He cannot see how to stop the train wreck from happening.
