The study says the virus, which is seeing a surge in monkeypox cases worldwide, may mutate faster than expected as it spreads from person to person.
This evolution may explain why this strain of monkeypox appears to be more contagious, Portuguese researchers Studies published in Nature Medicine On Friday.
Joan Paulo Gomes of the Portuguese National Institute of Health in Lisbon, one of the authors of the study, said the world is working on “outbreaks caused by existing viruses.” [many] More mutations than expected for this type of virus. “
“It was totally unexpected that so many mutations were found in the 2022 monkeypox virus,” Gomez said. “In fact, given the genomic characteristics of this type of virus, it is possible that only one or two mutations will appear each year.”
In fact, his team observed about 50. Viruses such as monkeypox tended to be relatively stable, and previous outbreaks tended to disappear each time a case was detected where the disease was not endemic.
World Health Organization is now Outbreak of monkeypox It should be classified as a public health emergency of international concern, which is the highest designation under international law. For example, Covid-19 is categorized as such. A decision may be made as early as Friday.
WHO does not have the authority to call the beginning of a pandemic, but in March 2020 it began using Covid’s terminology to raise awareness of the pandemic.
Gomez’s work used metagenomics to help reconstruct genomic sequences over time. His agency published the first draft genome of the virus in this outbreak last month.
Globally, health authorities are in close contact Track the progress of the outbreak.. New York City on Thursday has become the latest region for expanding vaccination. This qualifies men who have sex with men who have multiple or anonymous partners in the last 14 days. Previously, it provided a vaccine designed for smallpox, but it has been shown to provide protection against monkeypox to contacts in confirmed or possible cases.
Parts of the UK and Canada are expanding as well Vaccine useUses Imvanex from Bavarian Nordic in biotechnology. According to Our World in Data, more than 3,000 cases have been reported so far.
Monkeypox was first identified decades ago, but authorities point out that there is a relatively lack of literature on this subject. Some say this is due to the limited spread of the disease in the past.
