Dengue outbreaks are increasing in frequency over space and time, affecting people’s health and burdening resource-constrained health systems. The ability to detect early emerging outbreaks is key to mounting an effective response.
The early warning and response system (EWARS) is a toolkit that provides countries with early-warning systems for efficient and cost-effective local responses.
EWARS uses outbreak and alarm indicators to derive prediction models that can be used prospectively to predict a forthcoming dengue outbreak at district level.
EWARS is a pragmatic and useful tool for detecting imminent dengue outbreaks to trigger early response activities.
