I hope you are wrong but I have a feeling he isn’t too far off. I thought these virulent strains of the virus that have a ‘competitive advantages’ become weaker in order to survive in the host longer to continue to replicate and infect the population? It wants its host to live so it can survive and spread !
With that being said wouldn’t it be fair to say as the virus mutates it should become less and less deadly in people as it mutates? Is there a possibility that it becomes even more deadly or am I missing something?
