  Understanding differences in hospital case-fatality rates (HCFRs) of
coronavirus disease (COVID-19) may help evaluate its severity and the capacity
of the healthcare system to reduce mortality. We examined the variability in
HCFRs of COVID-19 in relation to spatial inequalities in socioeconomic factors
across the city of Sao Paulo, Brazil. We found that HCFRs were higher for men
and for individuals aged 60 years and older. Our models identified per capita
income as a significant factor that is negatively associated with the HCFRs of
COVID-19, even after adjusting by age, sex and presence of risk factors.
