LONDON (AP) — The World Health Organization says nearly 200 cases of monkeypox have been reported in more than 20 countries not usually known to have outbreaks of the unusual disease, but described the epidemic as “containable” and proposed creating a stockpile to equitably share the limited vaccines and drugs available worldwide. During a public briefing on Friday, the U.N. health agency said there are still many unanswered questions about how the current epidemic arose, but there is no evidence that any genetic changes in the virus are responsible for the unprecedented epidemic.
