Aerosol transmission of coronavirus in hospital / 上海预防医学

ABSTRACT

Coronavirus is human-to-human transmissible and often leads to nosocomial outbreak in the early stage, which poses a great threat to healthcare workers.Due to confined space, crowed population and some aerosol-generating medical procedures, hospital is vulnerable to coronavirus transmission and nosocomial infection.We review the mechanism and risk factors of coronavirus aerosol in hospital and summarize the evidence of aerosol transmission of three coronaviruses and the impact of air flow.Furthermore, we evaluate the effectiveness of personal protection in the above-mentioned scenarios for the prevention and control of nosocomial infection.
