The World Health Organization (WHO) declared Wednesday mpox a public health emergency of international concern (PHEIC), sounding the alarm over its potential for further international transmission.

"Today, the emergency committee met and advised me that, in its view, the situation constitutes a public health emergency of international concern. I have accepted that advice," WHO Director-General Tedros Adhanom Ghebreyesus told a press conference in Geneva.

A PHEIC is the highest level of alarm under international health law. "This is something that should concern us all ... The potential for further spread within Africa and beyond is very worrying," Tedros said.

Mpox cases reported so far this year have exceeded last year's total, with more than 14,000 cases and 524 deaths, according to WHO data.

WHO's declaration came after the Africa Centers for Disease Control and Prevention (Africa CDC) declared the ongoing mpox outbreak a public health emergency for the continent.

"We are not dealing with one outbreak of one clade – we are dealing with several outbreaks of different clades in different countries with different modes of transmission and different levels of risk," Tedros said in his opening remarks at the emergency committee meeting.

The European Union announced plans to procure and donate 175,420 doses of MVA-BN vaccines to Africa, as revealed by the European Commission's Health Emergency Preparedness and Response Authority (HERA) on Wednesday. Additionally, Denmark-based biotechnology company Bavarian Nordic will donate 40,000 doses of vaccine to HERA.
