The biggest puzzle in COVID, IMO, is the high asymptomatic rate in prisons and homeless shelters. Did it spread fast and most of them will go on to develop symptoms? Is it due to higher infectious disease load? (Similar to BCG and OPV vaccines maybe providing protection?)
Another mystery is how some places should be having severe epidemics by now but somehow seem relatively unscathed (Bali with somehow only 4 deaths and ~150 cases?!) https://twitter.com/expat_indo/status/1253482313935015936?s=21 …https://twitter.com/Expat_Indo/status/1253482313935015936 …
