I am starting to think that there might be way more than one strain to this virus. Which is scary because if that is true than even if you get immune to this virus once you had it you may only be immune to one strain. I've seen theories online but my own theory which may or may not make sense is, how come some people get it for just 2 days and lose sense of smell taste etc, while other don't lose taste at all? How come some people, even young like my friend of 32 years with no underlying health condition is in Hospital in critical condition? Is it possible he caught that other strain which is much more deadly while not so common?
