The coronavirus disease (COVID-19) is a novel emerging infectious disease spreading worldwide. To further understand the disease, we compared its clinical characteristics, symptoms and outcomes by gender. In an analysis of public surveillance data of Taiwan from January 21 to April 18, 2020, a total of 398 patients were diagnosed with COVID-19 by the detection of severe acute respiratory syndrome coronavirus 2 in pharynx swabs. We divided the patients into two groups: men and women. The associated data were collected, and multivariate comparisons of radiographic infiltration were conducted to analyse the gender-based differences. The mean incubation period was 5.4 ± 5 days, and the incubation period in men was 3.2 days longer than that in women (8 ± 8.1 vs. 4.8 ± 3, p = 0.05). The male patients with COVID-19 with infiltration in chest X-rays (CXR) were 12 years older than their female counterparts. The mortality rate in the male patients with COVID-19 was 6.4-fold higher than that in the female patients (3.2% vs. 0.5%, p < 0.05). The patients with comorbidities of diabetes mellitus and hypertension were vulnerable to infiltration in CXR and the patients with COVID-19 who had infiltration in CXR easily ended up with intubation, intensive care unit admission and mortality. Moreover, female patients with COVID-19 who had fever, cough and dyspnoea were susceptible to infiltration in CXR. Irrespective of whether the cases were imported female from Europe, America or Asia, indigenous male, the factors associated with death in patients with severe COVID-19 were male sex, elderly, female with fever, cough, dyspnoea and DM.
