The Duke and Duchess of Cambridge spoke with medical, charity and voluntary staff from across the Commonwealth, and their conversations highlighted a cause that's important to them both: The intersections of the pandemic and mental health. Kate and William had video calls with Dr. Zolelwa Sifumba from South Africa, Faysal Islam from Bangladesh and Heidy Quah from Malaysia to hear about how the coronavirus pandemic has affected front-line health-care workers there and what challenges it has given their mental well-being. Zolelwa said prior to the pandemic, front-line staff were also exposed to occupational illnesses. She had a personal experience with multi-drug-resistant tuberculosis as a medical student. But COVID-19 has posed new challenges, and she said it's important for communities to give health care workers as much support as possible.
