Wastewater Monitoring Results for 2025-12-07

December 11, 2025

Monitoring wastewater is essential for detecting viruses shed by individuals, providing early insights into infection trends and aiding public health responses. Recent data indicates stable levels of Influenza A and RSV, with Influenza B absent, helping track virus presence without indicating disease severity.

Monitoring wastewater is crucial because it allows us to detect viruses that people shed through urine and feces. This method provides early insights into infection trends and can identify changes in virus prevalence even when clinical testing rates decline. Such surveillance is vital for public health preparedness and response.

The most recent data shows that Influenza A is at 452,000 gc/l, RSV at 35,440 gc/l, and Influenza B is not detected. Compared to the past 30 days, Influenza A and RSV levels are stable, while Influenza B remains absent. Year-to-date, Influenza A is elevated, RSV is medium, and Influenza B is low. These levels do not indicate disease severity but help track virus presence.

Table 1 combines the last 7 days of virus activity, reflecting current conditions, while Table 2 shows annual historical peaks for long-term context. This helps determine if current levels are unusual or expected based on past data.

RSV is a respiratory virus affecting the lungs and airways. Influenza A and B are viruses that cause seasonal flu. RNA is a molecule that carries genetic information. PCR is a technique used to amplify small segments of DNA or RNA for analysis.
