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.
The fourth case was reported in Belgium on Saturday, said Emmanuel Andre, the official in charge of the National Reference lab for COVID-19 in Belgium. “This patient is being treated in Wallonia and is linked to the Antwerp event in which two other people were infected,” he wrote, referring to a festival that was held in the city earlier this month.
Monkeypox, which originates in Africa, is a virus related to smallpox and symptoms include a bumpy rash, a fever, sore muscles, and a headache. It's less deadly than smallpox, and health officials have said that its mortality rate is around 4 percent. Experts, however, have expressed concerns about monkeypox's spread beyond Africa in recent days.
White House officials, including President Joe Biden, said they are worried about the spread of the virus in public remarks issued on Sunday.
But Jha said that the administration is "confident we’re going to be able to get our arms around it ... but we’re going to track it very closely and use the tools we have to make sure that we continue to prevent further spread and take care of the people who get infected.”
In a Saturday update, the World Health Organization (WHO) said there were 92 confirmed cases in 12 different countries, with more under investigation. So far, cases have been confirmed in the United Kingdom, Italy, Sweden, Portugal, Belgium, Germany, France, Spain, the United States, Australia, and Canada.
Dr. Susan Hopkins, one of the top medical advisers to the UK Health Security Agency, warned over the weekend that there is community transmission of the virus in the United Kingdom.
Officials in Belgium and the United Kingdom said that it appears a significant portion of the virus's transmission is among homosexual males. In statements to local media, Belgian officials said that "we are observing transmissions among men who have sex with men," and it is a development "that we must study properly to better understand the dynamics."
