An estimate of the COVID-19 infection fatality rate in Brazil based on a seroprevalence survey	2020-08-21		.txt	text/plain	2975	186	61	title: An estimate of the COVID-19 infection fatality rate in Brazil based on a seroprevalence survey We infer the infection fatality rate (IFR) of SARS-CoV-2 in Brazil by combining three datasets. In order to estimate the IFR one needs not only an estimate of the number of deaths, but also of the total infected population, and then to compare both within the same time period. After adjusting for demography and under-ascertainment Verity et 15 On the other hand, a report by the group at Imperial College London estimated much higher values for the 16 Brazilian states they considered, 16 which, combined, suggest an overall IFR of 0.9%. The SIVEP-Gripe dataset contains the dates of symptoms onset and death for patients with SARS-CoV-2 positive RT-PCR test, together with their geographic location, which allow us to estimate the time delay τ sd between the development of symptoms and subsequent fatality.
