1) They have achieved the 70% seroprevalence threshold for herd immunity.
Cases have dropped now in the region, as expected.
@VincentRK @paimadhu
71% seroprevalence, the highest reported so far i~ 333000 cases
But confirmed cases are only 14711 (4.4%)
This means even assuming major undercounting, a lot of COVID, probably 80%, as expected is asymptomatic. @DrSidMukherjee
The Infection Fatality Rate (IFR) is ~0.7%.
Case fatality rate (CFR) for confirmed symptomatic cases was ~14%
CFR in Iquitos is similar to the mortality seen with symptomatic COVID in hotspots that got overwhelmed (NY, Lombardy)
