With a new strain developing overseas, the agency says those at high risk, including gay and bi men, should get vaccinated.
With a severe version of mpox breaking out in the Democratic Republic of Congo, officials with the U.S. Centers for Disease Control and Prevention are warning that it could spread and that people at risk should be vaccinated as soon as possible. High-risk populations include men who have sex with men, although anyone can contract the disease, which is largely spread by skin-to-skin contact — sexual relations, for instance, but also in crowds at outdoor festivals. Thousands of gay and bisexual men developed mpox in a 2022 outbreak. People with compromised immune systems, such as those living with HIV, are at high risk for serious cases and death. “There are two main types of mpox: Clade I, the type that is dominant in Congo, and Clade II, a version of which caused the 2022 global outbreak,” The New York Times reports. Clade I is deadlier than Clade II, the Times notes, explaining that “a clade is a genetically and clinically distinct group of viruses.” No Clade I cases have been documented outside of Congo yet, but a global spread is possible, as the 2022 outbreak that affected Europe and North America originated in Nigeria. “This is a very important example of how an infection anywhere is potentially an infection everywhere, and why we need to continue to improve disease surveillance globally,” Anne Rimoin, an epidemiologist at the University of California, Los Angeles, told the Times.
