Monkeypox mutates 12 times faster than expected, potentially making it more contagious than previous versions of the virus, experts warn
- The current strain of the monkeypox virus, which is circulating around the world, is mutating at a faster rate than expected
- Experts believe it has been in circulation since 2018 and has since mutated 12 times more than it should have
- The current outbreak includes more than 3,500 cases in nearly 50 countries, including just over 200 in the United States
- The researchers believe that the reason why this version of the virus was able to spread quickly is due to its many mutations.

The strain of monkeypox virus, which has appeared worldwide in recent weeks, can develop at an unusually rapid rate, making it more contagious than previous versions of the virus.
Researchers from the National Institutes of Health (NIH) found that the virus has reproduced up to 12 times its expected rate since 2018.
This means that the virus, which is usually thought to be spread by physical touch, contaminated surfaces or very close body contact, can be spread in ways that are not typical of normal tropical virus models.
That would explain the recent global update on monkeypox, which found 201 cases in 25 U.S. states and Washington, D.C., with more than 3,500 cases found worldwide in countries where the virus is not endemic.
The researchers found that the current strain of monkeypox virus, which has caused outbreaks of the tropical virus worldwide, mutated at a rate 12 times faster than expected. This potentially makes it more portable
Researchers, whose findings are yet to be officially published in nature, collected and studied 15 samples of the monkeypox virus for the study.
The NIH team restructured the genetic information of the viruses to find the number of changes the virus has undergone since the strain began circulating.
Although the virus was recently discovered in human populations, experts believe that this strain of West African monkeypox began to spread around the world in 2018.
How viruses mutate and circulate is a well-known science. DNA viruses such as monkeypox do not usually mutate quickly – as does COVID-19.
The nature of the virus allows it to correct errors that occur when replicated, leaving much less room for mutations – and in practice limiting the number of variants.
When researchers studied this strain of the virus, they found that it mutated between 6 and 12 times higher than the generally accepted norms for the virus.
Why exactly this cannot be determined, although experts believe that it may play a role in how the virus has managed to storm the world this year.
Cases of monkeypox have occurred in nearly 50 countries where it has not been endemic in recent weeks.
Although sometimes non-endemic nations will find cases – two were discovered in the United States in 2021 – infections are usually easy to detect and outbreaks can be controlled by health officials once they catch circulation.
However, this outbreak is different, with cases quickly found in masses around the world. This may signal that a more infectious version of the virus is imminent.
201 cases in the United States this year are estimated to be a serious understatement, as some experts warn that the country does not have the necessary testing and tracking capabilities to stay on top of each new case.

Some even fear that the virus will become endemic in the United States, Britain and other countries around the world.
Most of the infections that have been spotted as part of the current epidemic are among gay and bisexual men, both in the United States and across Europe.
California, the most populous state in the United States, has registered 51 infections so far – the most from any state. New York and Illinois also registered 35 and 26, respectively.
With the way the virus has spread through sexual networks, some fear that Pride’s celebrations in America last weekend could lead to a spike in cases.
In preparation, New York City health officials began administering monkey vaccines to the city’s population last week.
However, the supply of photos quickly declined, with visiting hours interrupted on Friday due to high demand.
As the strike takes about four days to fully activate, there are questions about whether the shots came too late to matter before the city’s pride parade, which hosts about two million people.
