Chicken pox spreads as an aerosol and has an R-value of 10 - 12 and a herd immunity threshold of about 90%, so pretty contagious. However, as several posters pointed out no mention of the virulence of the mutated SARS-CoV2 virus.
I haven’t looked for more up-to-date reports but in most countries (like the UK and Sweden) where the Indian variant is taking over, the number of hospitalizations, ICU-patients and deaths have not increased. Could mean that the virulence of the mutated virus is lower, or the fact that most people in the risk groups have been vaccinated, and are protected at least to some extent.
The fact that younger and healthier people get infected is really no problem. On the contrary, the immunity in the “herd” builds up and soon this plague will be nothing but a memory, just like the Russian flu of 1894 (which probably also was a Corona virus).
RE: where the Indian variant is taking over, the number of hospitalizations, ICU-patients and deaths have not increased.
Speaking of India, what’s happening over there?
It seemed to have peaked there at the end of May and declined.
