Though mpox has been a public health threat for years, in spring 2022 the disease spread much farther than previously and in many non-endemic nations, creating a broader crisis involving thousands of cases. Public health responded with vaccination efforts, guidance on disease detection and risk reduction, and other steps. The disease is caused by an orthopoxvirus and is in the same family as smallpox.
