The rapidly spreading monkeypox outbreak represents a global health emergency, the World Health Organisation's highest level of alert, WHO Director-General Tedros Adhanom Ghebreyesus said on Saturday.
The WHO label - a "public health emergency of international concern (PHEIC)" - is designed to trigger a coordinated international response and could unlock funding to collaborate on sharing vaccines and treatments.
Members of an expert committee that met on Thursday to discuss the potential recommendation were split on the decision, with nine members against and six in favour of the declaration, prompting Tedros himself to break the deadlock, he told reporters.
More than 16,000 cases have now been reported from 75 countries, said Tedros, adding that five deaths so far.
