The novel coronavirus belongs to the RNA virus, which has the possibility of mutation.
There are two types of viruses, DNA viruses and RNA viruses, RNA viruses are more prone to mutation than DNA viruses, DNA viruses are more stable, conservative and less prone to mutation, DNA viruses tend to only infest specific cells or lurk, avoid the immune system patrol, do a small amount of replication, and generally only infect one animal, such as chickenpox-zoster virus and smallpox virus are DNA But RNA viruses are different, they do not correct mistakes in the replication process, they just speed up replication and win in numbers, so the genetic mutation rate is high and eventually produce various variants, and have a strong ability to adapt to new host environments and transfer between different hosts, so it is difficult to track, monitor and study.
