When a virus is widely circulating in a population and causing many infections, the likelihood of the virus mutating increases. The more opportunities a virus has to spread, the more it replicates – and the more opportunities it has to undergo changes.
Stopping the spread at the source remains key. Current measures to reduce transmission – including frequent hand washing, wearing a mask, physi...
