Absolutely right as soon as you open up your borders and let people flow amongst others any virus still circulating will roar back to it’s natural R0 number the only way to get that R0 under one is with immunity in the vector hosts this immunity can come from inoculation or recovery from active exposure. For a MERS,SARS I, smallpox virus all.had 30+% CFRs lockdown of the sick and potentially sick is imperative with loss of contact tracing and documented community spread then isolation not just quarantine is warranted. For a virus with a CFR in the low one percent it does not make sense nor is it justified to isolate healthy people. The two situations are drastically different. Given that the MRNA has demonstrated effectiveness against deaths to such a degree look at Texas for an example there is zero.justification for the kind if lockdown Australia is doing that doesn’t mean it won’t work in Australia it will until they open up again and let in more viral vectors so you only delay the influx. The only way to beat a airborne bioweapon is with synthetic inoculation over a massive scale get your population above the RT threshold needed to drop the replication rate under one and the bug dies off for lack of hosts. For a R0 of 5 which is low for the Delta var chicken pox is 6+ and the data leaked shows at least as airborne as the pox you need 90%+ with immunity for the RT to drop under one. That’s basic immunological mathematics well proven with other historical airborne pathogens.
“Amongst”? I submit to you, friends, that this is no Texan. This is nothing but an out-of-state liberal pretending to be a Texan.
