Inferred infection-fatality rate from seroprevalence estimates for antibodies against severe acute respiratory syndrome coronavirus 2, Portugal. We used the registered number of deaths (on September 21, 2020) by age and sex  and our prevalence estimates based on seropositivity to infer the infection-fatality rate (Appendix) for more details. Numbers above bars indicate deaths per 1,000 persons.
