g into their public health systems in order to detect infectious diseases more rapidly, monitor outbreaks more effectively, and support evidence-based public health decision-making.
The report was developed in the context of the COVID-19 pandemic, which demonstrated the importance of genomic surveillance for identifying virus variants and enabling effective crisis management. The aim of the framework is to sustainably expand the capacities built during the pandemic and to apply them to additional pathogens beyond COVID-19.

uirements for detecting, confirming, reporting, and monitoring cholera cases and outbreaks.
The guidance explains the core functions of cholera surveillance, including case detection, laboratory testing (such as RDTs, culture, and PCR), routine data collection, outbreak notification, case and field investigation, data analysis, and performance monitoring. It also describes how surveillance strategies should be adapted depending on whether a country is experiencing no outbreak, clustered transmission, or community transmission.
Overall, the document aims to help countries establish adaptive, fit-for-purpose surveillance systems that enable early outbreak detection, guide timely response measures, and support long-term cholera control and elimination efforts.

es en Afrique. Il met en évidence le défi posé par le fait que les maladies infectieuses se propagent fréquemment au-delà des frontières en raison des mouvements de population, du commerce et des migrations, tandis que les systèmes de surveillance et les mécanismes de partage des données restent souvent centrés sur le niveau national et fragmentés.
Le cadre stratégique propose de renforcer la coordination régionale, d’harmoniser les systèmes de surveillance, d’améliorer le partage d’informations entre les pays et de développer les capacités des laboratoires ainsi que des ressources humaines. Il souligne également l’importance de la détection rapide des menaces sanitaires transfrontalières, des enquêtes conjointes sur les flambées épidémiques et d’une meilleure communication entre les États membres. Dans l’ensemble, le document vise à renforcer la préparation, les systèmes d’alerte précoce et la réponse collective aux menaces de santé publique sur le continent africain.

Ele destaca o desafio de que as doenças infecciosas frequentemente se propagam através das fronteiras devido ao movimento de pessoas, ao comércio e à migração, enquanto os sistemas de vigilância e os mecanismos de compartilhamento de dados permanecem muitas vezes centrados no nível nacional e fragmentados.
O quadro estratégico propõe fortalecer a coordenação regional, harmonizar os sistemas de vigilância, melhorar o intercâmbio de informações entre os países e desenvolver a capacidade dos laboratórios e dos recursos humanos. Também enfatiza a importância da detecção oportuna de ameaças sanitárias transfronteiriças, de investigações conjuntas de surtos e de uma comunicação aprimorada entre os Estados-membros. De modo geral, o documento visa reforçar a preparação, os sistemas de alerta precoce e a resposta coletiva às ameaças à saúde pública no continente africano.

during conflicts, natural disasters, or humanitarian crises, so that outbreaks can be identified before they spread widely and cause many deaths. The page also describes WHO’s approaches and tools for surveillance, including standardized data collection on attacks on health care, early warning, alert and response systems, and guidance materials that help countries monitor and analyse health threats, share information, and improve their early detection and response capacities during public health emergencies.

The guidance includes practical recommendations for how long contacts should be monitored (e.g., daily for 21 days without requiring quarantine if symptom-free) and advising good hygiene and reduced exposure risk during the monitoring period. This interim guidance is intended to support public health authorities worldwide in strengthening mpox outbreak detection, response, and reporting.
