The reason governments had to shut down economies is that in the face of a pandemic, we could not tell who was sick and who was not. While widespread testing followed by a vaccine eventually will curb this virus, what about the next one? As we have seen, it takes months to develop tests and remedies for a new disease and more than a year to develop a vaccine. We have learned from the flu that vaccines for viruses of this type are somewhat unreliable because they tend to mutate, and a vaccine for one strain may not work on a different strain.
