roviding key considerations for laboratories that allow the rationalization and optimization of testing during outbreaks. The recommendations given here have been prepared by WHO in consultation with, and reviewed by, global experts with experience in laboratory analysis of Corynebacterium species and in outbreak settings, or with expertise in developing new technologies for diphtheria research and diagnosis. Unless otherwise stated, the considerations provided apply to diphtheria outbreaks caused by toxin-producing C. diphtheriae with a classical respiratory diphtheria presentation.

WHO Director-General Dr Tedros Adhanom Ghebreyesus 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). Dr Tedros’s declaration came on the advice of an IHR Emergency Committee of independent experts who met earlier in the day to review data presented by experts from WHO and affected countries. The Committee informed the Director-General that it considers the upsurge of mpox to be a PHEIC, with potential to spread further across countries in Africa and possibly outside the continent.

The West African Ebola virus disease (EVD) outbreak in 2014 emerged in a region in Africa that had previously not reported any EVD outbreak. Subsequently, the
...
outbreak rapidly spread and was protracted in the three Mano River basin countries (Guinea, Sierra Leone and Liberia), with spillover cases in Nigeria, Senegal and Mali and, for the first time, importation into Europe and the USA. It became the most extensive and protracted EVD outbreak in history, followed by the 2018 outbreak in the Democratic Republic of the Congo (DRC). For the first time, cases were reported in urban centers, underscoring the urban spread of the disease. Its devastation had a far-reaching impact on lives in the three largely affected countries for years to follow. A total of 28,616 cases and 11,310 deaths were reported from Guinea, Sierra Leone and Liberia, with an additional 36 cases reported from Italy, Mali, Nigeria, Senegal, Spain, the UK and the USA.
