Monkeypox found to be evolving at a faster rate than expecte
The researchers collected samples from 15 patients and subjected them to genetic analysis to learn more about how quickly the virus is evolving. They found the virus has mutated at a rate six to 12 times as high as was expected. The researchers found signs suggesting that some of the mutations may have been due to exposure to the human immune system, most particularly enzymes of a type called APOBEC3—they kill viruses by inciting mistakes during copying of genetic code. If some of the viruses survived such an attack and passed on their genes, they would have given future generations a leg up against the human immune system. And that could explain why the virus has been mutating more rapidly than expected. The researchers also note that the virus may have been circulating at low levels in human communities or spreading among animals in other countries.
