Covid-19 infection is no longer perceived as a serious health problem, finds a large study that showed people still care about the health problems they were facing before the pandemic.

Over 10,000 people from countries including Colombia, South Africa, India, Kenya, Nigeria, Tanzania and Vietnam, ranked the seriousness of the seven health problems such as alcoholism and drug use, HIV/AIDS, malaria, tuberculosis, lung cancer and respiratory diseases caused by air pollution and smoking, and water-borne diseases like diarrhoea.
