Anybody can get the virus, however it is mainly only the older and those with underlying health conditions that it will be serious, also once you have had it you are immune and cannot pass it on, thus medics are looking at tests to find those that have had it so that they can get back to work in helping others and getting the economy back on track. (Both are vital if we are to survive)
One of the biggest problems at the moment is the shortage of test kits, even though manufacture has been ramped up. (According to the news New York only has a third of what is needed even though the US has massive manufacturing capacity)
