Israel and Switzerland are the latest countries to confirm monkey pox cases, bringing the total number of nations reporting outbreaks to 14.
According to the BBC, the Telegraph reports, the two countries said they had identified an infected person who had recently traveled, but Israel said it was investigating other suspected cases.
Otherwise, about 100 cases have been confirmed in the recent outbreak in Europe, USA, Canada and Australia.
The monkey line is most common in remote parts of Central and West Africa.
The outbreak has surprised scientists, but the monkey pox does not tend to spread easily among humans and the risk to the general public is said to be low.
The disease is usually mild and most people recover within a few weeks, according to health experts.
The World Health Organization has said another 50 suspected cases are being investigated - not to mention the countries involved - and warned that more infections are likely to be confirmed.
Asked about the blast as he concluded his visit to South Korea, US President Joe Biden said that if the virus spread more widely it would have "consequences", adding that "it is something that everyone should be concerned about". .
