In July 2022, the multi-country outbreak of mpox was declared a PHEIC as it spread rapidly via sexual contact across a range of countries where the virus had not been seen before. That PHEIC was declared over in May 2023 after there had been a sustained decline in global cases. What is mpox, mpox


WHO Regional Director for Africa Dr Matshidiso Moeti said, “Significant efforts are already underway in close collaboration with communities and governments, with our country teams working on the frontlines to help reinforce measures to curb mpox. With the growing spread of the virus, we’re scaling up further through coordinated international action to support countries bring the outbreaks to an end.”

Committee Chair Professor Dimie Ogoina said, “The current upsurge of mpox in parts of Africa, along with the spread of a new sexually transmissible strain of the monkeypox virus, is an emergency, not only for Africa, but for the entire globe. Mpox, originating in Africa, was neglected there, and later caused a global outbreak in 2022. It is time to act decisively to prevent history from repeating itself."

This PHEIC determination is the second in two years relating to mpox. Caused by an Orthopoxvirus, mpox was first detected in humans in 1970, in the DRC. The disease is considered endemic to countries in central and west Africa.

In July 2022, the multi-country outbreak of mpox was declared a PHEIC as it spread rapidly via sexual contact across a range of countries where the virus had not been seen before. That PHEIC was declared over in May 2023 after there had been a sustained decline in global cases.

Mpox has been reported in the DRC for more than a decade, and the number of cases reported each year has increased steadily over that period. Last year, reported cases increased significantly, and already the number of cases reported so far this year has exceeded last year’s total, with more than 15 600 cases and 537 deaths.

The emergence last year and rapid spread of a new virus strain in DRC, clade 1b, which appears to be spreading mainly through sexual networks, and its detection in countries neighbouring the DRC is especially concerning, and one of the main reasons for the declaration of the PHEIC.

In the past month, over 100 laboratory-confirmed cases of clade 1b have been reported in four countries neighbouring the DRC that have not reported mpox before: Burundi, Kenya, Rwanda and Uganda. Experts believe the true number of cases to be higher as a large proportion of clinically compatible cases have not been tested.

Several outbreaks of different clades of mpox have occurred in different countries, with different modes of transmission and different levels of risk.

The two vaccines currently in use for mpox are recommended by WHO’s Strategic Advisory Group of Experts on Immunization, and are also approved by WHO-listed national regulatory authorities, as well as by individual countries including Nigeria and the DRC.

Last week, the Director-General triggered the process for Emergency Use Listing for mpox vaccines, which will accelerate vaccine access for lower-income countries which have not yet issued their own national regulatory approval. Emergency Use Listing also enables partners including Gavi and UNICEF to procure vaccines for distribution.

WHO is working with countries and vaccine manufacturers on potential vaccine donations, and coordinating with partners through the interim Medical Countermeasures Network to facilitate equitable access to vaccines, therapeutics, diagnostics and other tools.

WHO anticipates an immediate funding requirement of an initial US$ 15 million to support surveillance, preparedness and response activities. A needs assessment is being undertaken across the three levels of the Organization.

To allow for an immediate scale up, WHO has released US$ 1.45 million from the WHO Contingency Fund for Emergencies and may need to release more in the coming days. The Organization appeals to donors to fund the full extent of needs of the mpox response.
