Early warning systems can mitigate the severity of measles outbreaks by reducing response times. However, existing systems are often too sensitive to be practical when it comes to identifying areas requiring reactive interventions. To address this issue, Catherine Eisenhauer presents a simple alternative system that combines a weekly and tri-weekly threshold for suspected cases. Initially evaluated in the DRC in 2022, the evaluation of this system is extended to to the context of Niger.

The video is in French. Find out more about the research in Niger on the Elrha study page.

Les systèmes d'alerte peuvent atténuer la gravité des épidémies de rougeole en réduisant les délais d'intervention. Cependant, les systèmes existants sont souvent trop sensibles pour être pratiques lorsqu'il s'agit d'identifier les zones nécessitant des interventions réactives. Pour remédier à ce problème, Catherine Eisenhauer présente un système alternatif simple qui combine un seuil de cas suspects hebdomadaire et trihebdomadaire. D'abord évalué en RDC en 2022, ici l'évaluation de ce système est étendue au contexte du Niger.
