Belgium has become the first country in the world to introduce a mandatory 21-day monkeypox quarantine for those who contract the virus after several cases were found, with a White House official warning Sunday that more U.S. cases are likely.
Those who contract the virus will have to self-isolate, confirmed Belgian health authorities to news outlets. Individuals who have had close contact with monkeypox cases aren’t required to self-isolate but should remain vigilant if they have been in contact with vulnerable people, officials said.
