WHO confirms first case of new mpox outside of Africa as outbreak spreads
- A patient in Sweden was infected while in Africa with the clade Ib version of the virus, thought to cause a more serious type of mpox
Global health officials on Thursday confirmed an infection with a new strain of the mpox virus in Sweden and linked it to a growing outbreak in Africa, the first sign of its spread outside the continent a day after the World Health Organization declared the disease a global public health emergency.
Swedish health officials said at a press conference that the person was infected while in Africa with the clade Ib type of mpox involved in the recent outbreak. The person is receiving treatment.
“The emergence of a case on the European continent could spur rapid international spread of mpox,” said Lawrence Gostin, a public health expert and professor at Georgetown Law in Washington. “A case in Sweden most likely means dozens of undetected cases in Europe.”
Dr Brian Ferguson of the University of Cambridge said the case in a Swedish traveller was concerning but not surprising, given the severity and spread of the outbreak in Africa.
“There will likely be more here and in other parts of the world as there are currently no mechanisms in place to stop imported cases of mpox happening,” he said.
