Introduction
The coronavirus disease 2019 (COVID-19) outbreak in China commenced in Wuhan in December, 2019. The virus spread rapidly due to its robust capacity for human-to-human transmission, long incubation period, and asymptomatic infection characteristics. In the early stages of the outbreak, it was inferred that the nosocomial infection rate could reach 41% without rapid intervention [1]. On January 20, 2020, the Chinese National Health Commission announced that COVID-19 had been included in the list of Class B infectious diseases categorized by the Chinese Law on the Prevention and Control of Infectious Diseases, and should be managed as a Class A infectious disease (for categorization and management principles of infectious diseases, please see Supplemental material I). Strict quarantine measures have been undertaken in Hubei province and other regions of China.
