[Principles and suggestions on biosafety protection of biological specimen preservation during prevalence of COVID-19].

Coronavirus disease 2019 (COVID-19) is a grade B infectious disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). In pace with the spreading of the disease, biosafety risk of the biological specimen preservation in biobanks has been significantly increased and biosafety protection during biological specimen preservation become increasingly important. According to the related national rules and the corresponding guidelines of Chinese Medical Association, this paper introduced the etiology about SARS-CoV-2, epidemiology about COVID-19, and the biosafety protection principles of individuals and biological specimen storage places in the process of personal protection, protection of collection, transport, handling, preservation, detection, post-detection disposal and emergencies of biological specimen. Emphasized to carry out a strict biosafety-risk assessment on biological specimen basing on virus load information, infectivity, and sample type (possible contact transmission, aerosol transmission, and fecal oral transmission).
