“…Data from the SARS-CoV2 epidemics in Ribeirão Preto, São Paulo, followed this distribution (Martinez et al, 2021). Positivity for the virologic test (RT-PCR) was 0.11% to 2.37% of the human population would be cumulatively infected with SARS-CoV2 by mid-June 2020 (Martinez et al, 2021). The local COVID-19 fatality rate was estimated to be 0.37%, or four deaths per 1,000 individuals infected (Martinez et al, 2021).…”
