  • Investigation and sensory control of surface and air pollution in isolation ward of severe COVID-19 patients

    ObjectiveTo evaluate the effect of disinfection measures in the isolation ward of ICU in severe patients infected with the Omilkerong variant of the new coronavirus, and to optimize the infection control measures. MethodsReferring to the patient's epidemiological and nucleic acid sample data, nucleic acid sampling was performed on the isolated ward environment by surface sampling method, and the nucleic acid Ct value of virus was detected by parallel fluorescence PCR method. The aerosol was collected by a wet-wall cyclone sampler, and the nucleic acid Ct value of the virus was detected by parallel fluorescence PCR. ResultsBefore daily disinfection, SARS-CoV-2 positive samples were found on the surface of the patient's ward and air sampling after the tracheoscopic tracheostomy. No positive samples of SARS-CoV-2 were found on the surface of articles and air in the patient's ward after daily disinfection. ConclusionThe daily disinfection measures of the hospital can achieve the effect of SARS-CoV-2 disinfection, which suggests that the surface of the articles in the ward after invasive operations such as tracheostomy and tracheoscopy, especially within 2 meters of the tracheostomy and the tracheostomy, is the key part of disinfection, which needs to be paid attention to.
