Prevention and Control of SARS-CoV-2 Infection in Clinical Laboratories: Implementation of Contingency Plan and Post-pandemic Response Strategies/ 临床实验室检测新型冠状病毒感染防控预案的制定及疫情后时代应对策略的思考

The outbreak of COVID-19 has currently been under control in China, but now the disease has rapidly evolved into a global pandemic We formulated a prevention and control plan for clinical laboratories responsible for detection of the novel coronavirus infection We analyzed the implementation of this plan and the problems arising from its clinical practice We found that the layout of most clinical laboratories (including gene amplification laboratories for clinical samples) was inadequate in response to a major outbreak and did not meet the requirements for biosafety protection and etiology and serology testing;and laboratory staff showed insufficiencies in their awareness regarding biosafety protection;the functions and status of the laboratory in the fever clinic need to be enhanced to increase its detection capacity;the high density of military personnel, the low level of automation of clinical laboratory equipment, and the lack of biosafety cabinets and personal protective equipment all limit the performance of diverse military operations and major overseas missions In view of these problems, we propose the following strategies and recommendations: the clinical laboratory needs to standardize the design and staff management according to the standards of P2 laboratory;the detection capacity and staffing of fever clinic laboratory in hospitals need to be strengthened, and a separate clinical gene amplification laboratory can be optimal;for those clinical gene amplification laboratories that fail to meet these standards, reconstruction and upgrade should be made according to the requirements of biosafety protection;for the clinical laboratory in the military medical system, in addition to enforcement of biological safety protection of the staff, sufficient supply of medical materials and biological safety equipment should be ensured and biological safety cabinets should be routinely equipped if possible
