New Crown Pneumonia Virus is an RNA virus. RNA is a single-stranded nucleic acid, which is more structurally unstable in form than double-stranded DNA, and is prone to mutation of bases.
Coronaviruses are relatively stable during replication due to proofreading mechanisms, but small probabilities of errors still occur, including mutations and deletions RNA viruses replication depends on RNA polymerase replication error correction function is limited, making RNA viruses mutate faster.
These errors may lead to the accumulation of mutations, and the direction of viral mutations is random and uncertain, so it is impossible to tell how pathogenic and transmissible the next mutated new coronavirus will be.
In case of dizziness and headache, fever, nausea and vomiting, it is important to go to the hospital immediately for diagnosis without delay.
