Clinical Data on Hospital Environmental Hygiene Monitoring and Medical Staffs Protection during the Coronavirus Disease 2019 Outbreak (preprint)

ABSTRACT

Background: The outbreak of coronavirus disease 2019 (COVID-19) has placed unprecedented challenges on hospital environmental hygiene and medical staff protection. It is crucial to assess hospital environmental hygiene to understand the most important environmental issues for controlling the spread of COVID-19 in hospitals. Objective: To detect the presence of COVID-19 in the samples from the area at risk of contamination in the First Hospital of Jilin University. Methods: Viruses in the air were collected by natural sedimentation and air particle sampler methods. Predetermined environmental surfaces were sampled using swabs at seven o'clock in the morning before disinfection. The real-time reverse-transcription PCR method was used to detect the existence of COVID-19 pathogens. Results: Viruses could be detected on the surfaces of the nurse station in the isolation area with suspected patients and in the air of the isolation ward with an intensive care patient. Conclusion: Comprehensive monitoring of hospital environmental hygiene during pandemic outbreaks is conducive to the refinement of hospital infection control. It is of great significance to ensure the safety of medical treatment and the quality of hospital infection control through the monitoring of environmental hygiene.
