People join a queue to buy maize meal at a supermarket in Harare, Zimbabwe, Wednesday, March 25, 2020.   Zimbabwe's public hospital doctors went on strike Wednesday over what they called a lack of adequate protective gear as the coronavirus begins to spread in a country whose health system has almost collapsed.  The new coronavirus causes mild or moderate symptoms for most people, but for some, especially older adults and people with existing health problems, it can cause more severe illness or death.
