 How to deal with the cases of return to work? Beijing CDC issues prevention and control guidelines


At the same time, the prevention and control guidelines make it clear that no matter whether the confirmed cases are confirmed outside the work unit or on the job, the places for resumption of work shall cooperate with the disease control agency to carry out on-site epidemiological investigation, and the disease control agency shall determine the close contacts and general contacts according to the activity scope and contact personnel of all cases in the place. According to the requirements, the close contacts should carry out centralized medical observation and nucleic acid detection. General contacts carry out home medical observation and nucleic acid detection as required. According to the assessment results, the centralized air conditioning and ventilation system should be cleaned and disinfected in the return to work place. According to the epidemiological investigation and epidemic characteristics on site, all places should cooperate with the disease control agency to carry out sampling and testing in key areas of the external environment. The return to work site shall cooperate to complete the final disinfection of the work area, living room, activity area and company vehicles that may be polluted by the case.

The disease control department gives comprehensive suggestions for two situations:

Based on the analysis of the above two cases with different characteristics, it is found that the source of infection, post characteristics, activity scope, contact personnel, internal environment, structural characteristics, ventilation, business contacts and other complex conditions of the case affect the spread range of the epidemic when the case occurs in the place of resumption of work. Therefore, the epidemic prevention and control measures should be considered in combination with the on-site epidemiological investigation and risk assessment. The main prevention and control measures include the following aspects.

1. All cases were isolated to the designated medical institutions for treatment. After discharge, isolation medical observation was continued for 14 days to pay close attention to the health status of the cases.

2. The return to work site shall cooperate with the disease control organization to carry out on-site epidemiological investigation. According to the activity scope and contact personnel of all cases in the site, the disease control organization shall determine the close contacts and general contacts. According to the requirements, the close contacts should carry out centralized medical observation and nucleic acid detection. General contacts carry out home medical observation and nucleic acid detection as required.

3. According to the indoor ventilation and air conditioning operation conditions of the site and the investigation and evaluation results, the centralized air conditioning and ventilation system shall be cleaned and disinfected in the resumption of work site, and the measures such as closing the return air of all or part of the air conditioning units in the site, operating with fresh air, increasing the exhaust air volume, opening the external windows connected with the external environment, etc. shall be taken.

4. According to the on-site epidemiological investigation and epidemic characteristics, all sites need to cooperate with disease control agencies to carry out sampling and testing in key areas of the external environment.

5. The return to work site shall cooperate to complete the final disinfection of the work area, living room, activity area and company vehicles that may be polluted by the case. Carry out preventive disinfection in daily work.

6. According to the on-site epidemiological investigation and risk assessment results, the site for resumption of work and production shall decide whether to implement measures such as reducing the work rate, closing management or stopping production according to the actual situation.

7. Carry out publicity, education, communication and guidance for the employees of the unit, and do a good job of health monitoring for the employees, and timely report and seek medical treatment in case of any abnormality.

8. According to the impact of the characteristics of the units and places returning to work on the spread of the epidemic, other targeted prevention and control measures are proposed.
