I wrote down the reason why the virus is “getting” weaker. There is no explanation of the phenomena in the article, the doctor just talks about what he experiences without an explanation. Social distancing alone wouldn’t help us, we also need the herd immunity, otherwise the virus would just flare up randomly the second we ease the restrictions. The mechanism I mentioned helps us to achieve herd immunity with time. I don’t understand why is that getting downvoted...
Meanwhile I found the article:
