The World Health Organization declared mpox a global public health emergency for the second time in two years, following an outbreak of the viral infection in the Democratic Republic of Congo that has spread to neighbouring countries.
A new form of the virus, clade Ib, triggered global concern as it seems to be spreading quickly and little is known about the strain. The disease transmits through close contact.
The new strain has spread to at least two countries outside Africa.
The following are the countries that have reported cases of clade Ib mpox:
DEMOCRATIC REPUBLIC OF CONGO
Two strains of mpox are spreading in the Democratic Republic of Congo – the endemic clade I and the new clade Ib, which spreads more easily through close contact, including sexual.
As of August 11, DRC has seen a total of 3,235 cases and 19 deaths in 2024. The country has confirmed 38 cases of mpox in the past two weeks, according to WHO data.
SWEDEN
Global health officials on August 15 confirmed an infection with a new strain of the mpox virus in Sweden, the first sign of its spread outside the African continent.
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.
