"Who is @CovidAnalysis We are PhD researchers, scientists, people who hope to make a contribution, even if it is only very minor. You can find our research in journals like Science and Nature. For examples of why we can't be more specific search for "raoult death threats" or "simone gold fired". We have little interest in adding to our publication lists, being in the news, or being on TV (we have done all of these things before but feel there are more important things in life now)."
