I found this editorial by Holman Jenkin interesting in the questions it raises about what we have learned about Sars Cov 2 -
He describes evidence of active Corona virus in South America and Europe BEFORE the pandemic was recognized in Wuhan - via sewage and antibody studies, which suggests the virus had already crossed the globe by January 2020.
Why has the virus reactivated in many places - US, Uk, Spain, but apparently not in Italy?? What are the Italians doing differently?
Another question is what is happening with the Corona virus in China where most believe the viral illness has disappeared as reported by the Chinese media?
Why then are they vaccinating hundreds of thousands of people with an untested vaccine - and how do they know if the vaccine is effective if there is no Sars Cov 2 actually occurring in China?
Lots of interesting things to consider - worth a read
And a New York Times article about how Covid 19 is acting in India. It may make some grandparents a bit more cautious.
