“There’s an ********** of cases in Central *******, particularly in the (Democratic Republic of Congo), and there cases that are occurring in the surrounding countries, including Kenya, Rwanda and Uganda,” he told Global News.

“I think the countries that are under-resourced in terms of surveillance and in terms of management will have more deaths. And it’s affecting very young children. (There are) very high rates of mortality with this strain – it’s really important to get it under control.”

Originally identified in monkeys in 1958, mpox, previously known as monkeypox, was primarily confined to central and western *******, and transmitted through close contact with infected animals.

However, a shift occurred in 2022 when the virus spread rapidly among people worldwide, including Europe, North America and beyond.

******* has reported a staggering surge in mpox cases this year, with at least 14,000 infections and 524 deaths — a 160 per cent increase compared to the same ******* last year, according to the WHO.

The WHO said mpox was recently identified for the first time in four East ******** countries: Burundi, Kenya, Rwanda and Uganda. All of those outbreaks were linked to the epidemic in the Democratic Republic of Congo.

In the Ivory Coast and South *******, health authorities have reported outbreaks of a different and less dangerous version of mpox that spread worldwide in 2022.

The outbreak disproportionately affected gay and ********* men, and other men who have **** with men between the ages of 18 and 49 years. Most cases were reported in Ontario, Quebec and British Columbia.

While case numbers declined following the initial outbreak, a gradual increase in infections has been observed since early 2024 — mainly in Toronto, said Shahin.

“And more of a spike in June and July. It may be related to events such as Pride where people are meeting more partners, and (are) more social in the summertime. It’s hard to really say for sure exactly what’s behind it,” she said.
