“Viruses are always mutating, its how they survive, and nothing to be alarmed about, as the mutations may be more infectious but less serious health wise.”
Or mutations could lead to more virulence and less infectious, or more virulent AND more infectious or less virulent AND less infectious. It’s random, we can’t know until it occurs. Each infected human is an experimental petri dish, the more infections the more likely a mutation.
What would they be? There are very few effective anti viral treatments for any virus. There are treatments to ameliorate symptoms and supportive measures but no real cures in the same way as antibiotics kill bacteria.
