The World Health Organization said Tuesday it would hold an emergency meeting next week to determine whether to classify the global monkeypox outbreak as a public health emergency of international concern.

The UN agency is also working to change the name of the disease, which was long confined to Western and Central Africa until more than 1,000 cases were detected in dozens of countries across the world over the last two months.

"The outbreak of monkeypox is unusual and concerning," World Health Organization chief Tedros Adhanom Ghebreyesus told journalists.
