What wastewater surveillance measures
Public programs sample municipal wastewater to estimate how much viral RNA from certain pathogens is present over time. Trends can rise before hospital admissions peak, which is why officials describe it as an early signal rather than a case count.
Strengths and limits
Wastewater data reflects community-level mixing; it does not tell you who is sick or where they live at street level. Laboratory testing, syndromic surveillance, and clinical care data remain essential.
RSV, influenza, and COVID-19
Agencies may run combined dashboards or separate tracks. Naming and units differ by jurisdiction; always read the methodology PDF or FAQ on the publisher site.
