I'm calling my shot. Covid needs 20% for herd immunity. With only 1 in 10 people being symptomatic and actually getting tested, Florida will achieve herd immunity this week or next and the number of new cases will begin to decline dramatically.
It's based largely on the new
'theory' of how Sweden's has this massive
'drop off.'
It's related to the emerging evidence that any Coronavirus and T-cell backed immunity -- including various, common colds -- are providing
'resistance' against most SARS-CoV -- including SARS-CoV-2 (COVID-19) -- infections.
I.e., 20% SARS-CoV-2 =~ 90% overall Coronavirus T-cells distribution
Sweden has had death rates similar to
'shutdown' European nations, especially the UK, but without the massive impact to their economies.
The theory includes that keeping
'human interaction up' kept more people dealing with
'resistance' to all coronaviruses in general. This also explains why
'pockets' of
'outbreaks' occurred in high density populations, even with the lockdown. Especially in the high density concentrations of the UK and US.
I.e., families repeatedly
'passed' it to each other, in close proximity, while
'strangers' weren't
'as close,' and received 'lower amounts' ... ones
'easier to fight.'
It's like anything else, you get a big dose, replication happens faster. You get a smaller dose, and it's far, far less and your body
'fights' it better -- especially when healthy, and then
'learns' how to fight it.
This is just a
'theory,' and I'm probably butchering it / over-simplifying it. It does fit the
'curves' though.
In Florida's case, it was the mass influx of tourists, often
'close families,' from higher infection states too, especially ones that felt they were
'on vacation' and stopped
'caring' about distancing and
'hygiene.'
