The new coronavirus genetic information transmission pathway is through RNA reverse transcription replication. The genetic material of organisms can be divided into DNA and RNA, the genetic information material of the new coronavirus is RNA, so the genetic information of the new coronavirus can be passed through the reverse transcription and replication of RNA. The new coronavirus is RNA virus single chain structure, with instability, so the virus in the body replication, reverse transcription process, easy to virus mutation, mutated virus pathogenicity and infectiousness have certain differences, scientists are also in the continuous research. The new coronavirus will be transmitted through droplets, aerosols, direct contact and other channels, the general public need to pay attention to strengthen the protection, wash their hands diligently, wear masks.
