One of the reasons that a large percentage of Covid cases have been asymptomatic or mild is that the initial infectious doses have been minimal. Face masks and such have helped in that. Now, however, the Covid virus has mutated a new offensive attack — it has dramatically increased the early rate and volume of production of viral particles produced in the respiratory tract at the onset of the disease such that standard protocols are not enough to maintain the lower levels of illness that we’d grown accustomed to. Indeed, the amount of the initial infectious doses have increased, thus increasing the potential seriousness of the illness experienced.
It seems that the Delta wave will crest in mid-October and put us much closer to herd immunity.
Note: To avoid vaccination is one thing because of concern about side effects; but, choosing not to wear a face mask is a bit like playing Russian Roulette.
