U.S. prepares for possible arrival of more severe strain of mpox
Senior Biden administration officials said the U.S. is preparing for the arrival of a more severe version of mpox. Clade 1 has caused more than 600 deaths in Africa.
Senior Biden administration officials said Friday that the United States is preparing for the possible arrival of a more severe version of mpox, which has taken off in the Democratic Republic of Congo and other countries in Africa resulting in more than 600 deaths there.
As of Thursday, there have been more than 24,800 reported cases of this version of the virus, known as clade 1, so far this year, the World Health Organization said at a separate briefing Friday. The WHO declared the outbreak a global health emergency in August.
Last month, Sweden confirmed a case of clade 1, the first known case outside of Africa, followed by a case in Thailand several days later. Both patients had spent time in Africa.
A different version of mpox, clade 2, triggered a global outbreak in 2022 and a surge of cases in the U.S. Clade 1 is more severe and can kill up to 10% of people infected, though recent death rates have been around 1% to 3.3%, according to the CDC.
On a call with reporters, senior administration officials said that as infections have risen in Africa, the U.S. has been gearing up for its own cases.
