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).

10.Replication and transmission mechanisms of highly pathogenic human coronaviruses.
Journal of Zhejiang University. Medical sciences 2020;49(1):324-339
The three known human highly pathogenic coronaviruses are severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus, (MERS-CoV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Human highly pathogenic coronaviruses are composed of non-structural proteins, structural proteins and accessory proteins. Viral particles recognize host receptors via spike glycoprotein (S protein), enter host cells by membrane fusion, replicate in host cells through large replication-transcription complexes, and promote proliferation by interfering with and suppressing the host's immune response. Human highly pathogenic coronaviruses are hosted by humans and vertebrates. Viral particles are transmitted through droplets, contact and aerosols or likely through digestive tract, urine, eyes and other routes. This review discusses the mechanisms of proliferation and transmission of highly pathogenic human coronaviruses based on the results of existing research, providing basis for future study on interrupting the transmission and pathogenicity of human highly pathogenic coronaviruses.
