A nationwide analysis of data from the first 6 months of the COVID-19 pandemic in Argentina has identified factors associated with increased risk of death or admission to an intensive care unit (ICU) due to the disease, including older age, male sex, coma, seizures, and underlying comorbidities. Daniel Schoenfeld of Centro Diagnostico San Jorge in Puerto Madryn, Argentina, and colleagues present these findings in the open-access journal PLOS ONE on February 11.
