Such a spillover could then allow the virus to remain in an environment, jumping between animals and humans over time. If we continue to see sustained person-to-person transmission in this outbreak, even at low levels, that brings the possibility of a spillover back into animals in nonendemic countries from “an existential threat to a distinct possibility,” Rimoin told CNN.

On Wednesday, May 18, 2022, Portuguese health authorities confirmed five cases of monkeypox in young men, marking an unusual outbreak in Europe of a disease typically limited to Africa. This 2003 electron microscope image made available by the Centers for Disease Control and Prevention shows mature, oval-shaped monkeypox virions, left, and spherical immature virions, right, obtained from a sample of human skin associated with the 2003 prairie dog outbreak. Once the virus is circulating among these animals, it can continue jumping back into humans who might come into contact with infected squirrels or guinea pigs, for example. Previous human cases of monkeypox weren’t thought to be too far removed from some initial exposure to an infected animal – typically rodents. I mean, are we on episode two, or are we on episode four, or are we on episode 10? And how many episodes are in this series? We don’t know.” “It’s like we’ve now decided to watch a new series, but we don’t know exactly which episode we’ve landed on. “This could have been spreading silently for a while. “We don’t even know how long this has been spreading,” Rimoin said. The latest monkeypox outbreak is proving difficult to predict in part because we haven’t been able to fully trace its origins. “If monkeypox were to become established in a wildlife reservoir outside Africa, the public health setback would be difficult to reverse,” Rimoin, now a professor of epidemiology at the UCLA Fielding School of Public Health, warned in a 2010 article published in the Proceedings of the National Academy of Sciences. ‘We don’t even know how long this has been spreading’Įpidemiologist Anne Rimoin has been studying monkeypox for about two decades and has long warned that its spread in places like the Democratic Republic of the Congo could have broader global health implications. If research continues to show that the virus has spread more among humans than previously thought – more distant from an animal source, that is – Worobey said one “really good question” is, why wouldn’t the world think monkeypox can be endemic in places beyond West and Central Africa? “We need to actually turn our attention to where it’s been spreading … and start caring about that population just as much as we care about what’s going on in all these other countries around the world.” “It’s really a tale of two outbreaks,” Worobey said. And it means the world has failed to protect those in resource-limited areas where it has been endemic and to control it at its source before it spread globally, he added. Michael Worobey, an evolutionary biologist and professor at the University of Arizona who was not involved in the research, said it suggests that “this outbreak has been going on for a long time, locally,” as in where the virus is endemic. In that research, genetic sequences showed that the first monkeypox cases in 2022 appear to have descended from an outbreak that resulted in cases in Singapore, Israel, Nigeria and the United Kingdom from 2017 to 2019.
