Abstract:Objective To survey a suspected hospital-transmitted COVID-19 outbreak in a city of Hunan Province, and to analyze the transmission factors so as to provide references for prevention and control of the COVID-19 epidemic. Methods Epidemiological investigation and nucleic acid test were carried out on cases and their close contacts, and on-site hygienic investigation was conducted at suspected exposure sites. Results Case A was a domestically-imported COVID-19 case from Hubei. In temporary isolation single room without negative pressure of respiratory intensive care unit (RICU) in the hospital, case A possibly spread COVID-19 to case B near the isolation gate. After transferring to the general ward of pneumology department, case B spread COVID-19 to the two family escorts (case C and case D) and the patient on the adjacent bed (case E). Conclusion The COVID-19 in the temporary isolation single room without negative pressure may be transmitted to the patients on the adjacent beds. Hospital isolation wards should be built according to the standards and infection control measuresshould be reinforcedso as to avoid nosocomial transmission.
