The demographics of the study cohort are detailed in Table 1. Patients with exposure history (recent travel to Wuhan or contact with infected patient) accounted for 85.2% of study cohort. Fever (84.1%) and cough (56.8%) were the most common presenting symptoms. Low lymphocyte and white cell counts were observed in 26.4% and 25.0% of patients, while high C-reactive protein was observed in 55.0% of patients.
