On
Monday, former US Food and Drug Administration (FDA) chief Scott Gottlieb said
in an interview to CNBC that his estimate is that by the end of the year 30% of
Americans would have been infected by the Sars-CoV-2 virus which causes the
coronavirus disease. That?s almost one in three Americans who will have some
sort of immunity against the virus. I know there is a lot of confusing research
on this, especially when it comes to those asymptomatic patients who have low
viral loads, but I am going to go with the most comprehensive research - Dispatch 207 on November 19 covered it - that most infected people have at
least six months of protection (of some sort) against Covid-19, with a not
insignificant probability that this protection could actually last for years.
Gottlieb went on to add in the interview that he believes some states may have
an infection rate of up to 50%.
