Coronaviruses belong to the family Coronaviruses and the genus Coronaviruses. Coronaviruses are a class of RNA viruses with a capsule membrane and a linear single positive strand genome, which is a large class of viruses widely existing in nature. The 5 'end of the virus genome has A methylated cap structure, and the 3' end has a poly(A) tail. The total length of the genome is 27 ~ 32kb, which is the largest genome among the known RNA viruses.

Coronaviruses only infect vertebrates, are associated with a variety of diseases in humans and animals, and can cause respiratory, digestive and nervous system diseases in humans and animals.
