According to health authorities and local media reports, several European nations, the United States, Canada, and the United Kingdom are investigating suspected and confirmed cases of monkeypox.
The most recent recorded cases were in France, Italy, and Sweden.
It follows Wednesday's confirmation of cases in the United States, Spain, and Portugal and the inquiry into 13 suspected cases in Canada.
Monkeypox is especially prevalent in isolated regions of West and Central Africa.
Cases of the disease outside the region are frequently associated with travel to the area.
According to the National Health Service of the United Kingdom, monkeypox is a rare viral infection that is often mild and from which the majority of patients recover in a few weeks.
The virus does not travel easily between individuals, and the risk to the general population is reportedly minimal.
On May 7, the first case of the disease was reported in the United Kingdom. According to the UK Health Security Agency, the patient recently visited Nigeria, where they are believed to have contracted the illness before traveling to England.
The United Kingdom now has nine verified cases. These diseases have not yet been determined, although the World Health Organization (WHO) believes they were "locally acquired."
Three confirmed cases were announced in Europe on Thursday: one in Sweden, one in Italy, and one in France. Local media said that the individual in Italy had recently returned from the Canary Islands, while Swedish authorities were uncertain how the individual caught the virus.
Additionally, on Wednesday, five confirmed cases were recorded in Portugal and seven in Spain.
According to El Pas, although no vaccination has been approved for Monkeypox in Europe, Spanish health authorities have purchased thousands of smallpox vaccines to combat the outbreak. Monkeypox belongs to the same virus family as smallpox.
In North America, health officials in Massachusetts, United States, have confirmed that a man has contracted monkeypox.
Recent media reports indicate that thirteen probable instances of the virus are being investigated in Canada.
According to health officials, the man has been hospitalized and presents no threat to the public.
