Do African nations have as much reason to fear Covid-19 as regions where so much of the population is older? According to Professor Alex Broadbent, the biggest public health risk in Africa is not Covid-19, but the consequences of regional and global measures designed to reduce its effect on public health. He further says, when we lock down, we are making a choice - we are saving the lives of some older people, and causing the deaths of some younger peo--ple, especially children, who are most at risk of malnutrition and diseases of poverty.
