Public health significance of coronaviruses carried by aquatic animals / 公共卫生与预防医学

ABSTRACT

This paper reviews the coronavirus species and post-infection symptoms of aquatic animals such as marine mammals, ferrets, fish, and waterfowl, analyzes the activity and transmission of coronaviruses in the aquatic environment, compares the homology of aquatic coronaviruses with SARS-CoV-2, and assesses the zoonotic risk. The results showed that aquatic animal coronaviruses were mainly α, γ, δ coronavirus and Alphaletovirus. SARS⁃CoV⁃2 is more similar to marine mammal coronavirus (51.90%-52.30%) and less similar to fish, mink, duck and goose coronavirus (43.30%-47.90%). The risk of transmission of coronaviruses carried by minks and marine mammals to humans is relatively greater, and from fish and waterfowl to humans is relatively small. By elaborating on the situation of coronavirus infection in aquatic animals, this paper is conducive to solving related issues such as the prevention and control of coronavirus epidemics, which is of great significance to ecosystems and public health.
