Abstract
ObjectiveTo understand the presence and distribution of novel coronaviruses in the external environment of confirmed COVID-19 cases.
MethodsEnvironmental surface swab specimens such as bed rails, doorknob, closestool, hand washing sink, table, locker, ward pager, mobile phone, cup, clothes, were collected from the sentinel hospital of COVID-19, for the nucleic acid detection by RT-PCR.
ResultsA total of 150 environmental samples were collected from 30 confirmed COVID-19 cases, 6 samples were determined to be novel coronaviruses postive (positive rate 4.00%). Of a total of 14 mobile phone, 3 showed novel coronaviruses positive. Among the 30 confirmed COVID-19 cases, 6 cases (positive rate 20.00%) were found novel coronaviruses in the external environment.
