Three new states confirm the first cases with the Monkey Line
Israel, Switzerland and Austria are the latest countries to confirm Monkeypox cases, bringing the total number of countries reporting outbreaks to 15.
Israel and Switzerland have identified a case, respectively, imported from travel. Israel is investigating other suspected cases.
Monkey pox does not tend to spread easily among humans and the disease is usually mild.
The virus is most common in remote parts of Central and West Africa.
More than 80 cases have been confirmed in recent outbreaks in Europe, the US, Canada and Australia.
The World Health Organization has said a number of other 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 a visit to South Korea, US President Joe Biden said the virus is something everyone should be concerned about. He said the US is working hard to find out what vaccine can be used.
After the outbreak was first identified in the UK, the virus began to be detected across Europe: in Spain, Portugal, Germany, Belgium, France, the Netherlands, Italy and Sweden.
Although there is no specific vaccine for monkeypox, some countries have said they are stockpiling vaccines, which are about 85% effective in preventing infection because the two viruses are quite similar.
