New Guidance Aims to Sharpen Early-Warning Signals in Epidemic Surveillance

A new study published in PLOS Digital Health provides methodological recommendations for analyzing leading indicators in real-time epidemic surveillance. The guidance aims to improve the reliability of early-warning systems, such as wastewater monitoring and syndromic surveillance, which expanded significantly after the COVID-19 pandemic. Rigorous analysis of these signals could provide crucial time to manage outbreaks effectively.
