It's interesting to note that the scientist quoted in the article has "no background as an epidemiologist". He's a chemist. I take that as just another voice in the crowded field of voices right now.
It is also interesting to note that one of the foremost epidemiologist in the U.S. (Fauci) and many other of his counterparts got it completely wrong about how to handle this Covid problem and where it was headed. This quote from the author of the article, Prof Levitt, seems to be spot on. "The problem with epidemiologists is that they feel their job is to frighten people into lockdown, social distancing. So you say 'there's going to be a million deaths' and when there are only 25,000 you say 'it's good you listened to my advice'. This happened with Ebola and bird flu. It's just part of the madness." I would rarely discount a 'numbers guy" as just another voice in the crowded field of voices. He seems to have a better prediction with Covid that the "experts".
