A day after the disease was designated a worldwide public health emergency, the World Health Organisation (WHO) announced on Thursday that a case of the viral infection mpox in Sweden was connected to an outbreak in Africa, marking the first indication of its spread outside of the continent this year.
At a news briefing, Swedish health experts stated that the individual contracted the clade Ib kind of mpox, which is responsible for the current outbreak while travelling in Africa. The patient is undergoing medical care.
According to representatives from both the US and Canada, no cases have been found thus far.
Following the spread of infections from the Democratic Republic of the Congo to neighbouring countries, the WHO on Wednesday deemed the African outbreak to be a public health emergency.
Most reported cases of the disease outside Africa in 2023 were identified through sexual health or other health services in primary or secondary healthcare facilities, and involved mainly, but not exclusively, men who have sex with men.
In May 2023, WHO declared that the disease was no longer a global challenge. Its director-general of the body, Tedros Adhanom Ghebreyesus declared the end of the emergency status for the disease noting that almost 90% fewer mpox cases were reported in the past three months, compared with cases in the same duration before that. More than 87,000 mpox cases were confirmed globally from the beginning of 2022 through May 8 this year.
But a fresh trend of the disease has sprung again this year with the Democratic Republic of Congo remaining the epicentre.
The virus that is causing the current outbreak, Clade Ib, is thought to induce a more severe form of mpox than the one that resulted in a public health emergency in 2022. Close contact is how the virus spreads.
The viral infection spreads by intimate contact and results in lesions filled with pus and flu-like symptoms. Although most cases are mild and can be fatal.
