The ever-growing monkeypox outbreak in over 70 countries is an "extraordinary" situation that now qualifies as a global emergency, according to the World Health Organisation (WHO).
The UN health agency's declaration could spur further investment in treating the once-rare disease - and also worsen the scramble for scarce vaccines.
Although monkeypox has been established in parts of central and west Africa for decades, it was not known to spark large outbreaks beyond the continent or to spread widely among people until May, when authorities detected dozens of epidemics in Europe, North America and elsewhere.
Declaring a global emergency means the monkeypox outbreak is an "extraordinary event" that could spill over into more countries and requires a coordinated global response.
The WHO previously declared emergencies for public health crises such as the Covid-19 pandemic, the 2014 West African Ebola outbreak, the Zika virus in Latin America in 2016 and the ongoing effort to eradicate polio.
The emergency declaration mostly serves as a plea to draw more global resources and attention to an outbreak.
