evidence: WHO declares mpox outbreak a public health emergency of international concern [...] The World Health Organisation (WHO) has determined that the upsurge of mpox in the Democratic Republic of the Congo (DRC) and a growing number of countries in Africa constitutes a public health emergency of international concern (PHEIC) under the International Health Regulations (2005) (IHR). The declaration follows advice of an IHR Emergency Committee of independent experts who met on Wednesday (14 August 2024) to review data presented from the WHO and affected countries. The committee considered the upsurge of mpox to be a PHEIC, with potential to spread further across countries in Africa and possibly outside the continent.
