Abstract

Background: As the coronavirus disease 2019 (COVID-19) outbreak accelerates worldwide, it is important to evaluate sex-specific clinical characteristics and outcomes, which may affect public health policies. Methods: Patients with COVID-19 admitted to Tongji Hospital between 18 January and 27 March 2020 were evaluated.

Risk factors for mortality in the whole population, females, and males were determined respectively. Results: There were 1667 (50.38%) females among the 3309 patients. The mortality rate was 5.9% in females but 12.7% in males. Compared with males, more females had no initial symptoms (11.1% vs 8.3%, P†=†.008). Complications including acute respiratory distress syndrome, acute kidney injury, septic shock, cardiac injury, and coagulation disorder were less common in females; critical illness was also significantly less common in females (31.1% vs 39.4%, Pâ€
