How do we use #wastewater to monitor infectious diseases like #influenza and #RSV?

📅 Wastewater treatment plants send samples to our lab partner weekly
🧪 Samples are tested for a dozen infectious diseases
📊 Results are posted on our #data dashboard

📊 WWSCAN Weekly Data:

Rare pathogens overview: All rare pathogens, other than Mpox clade Ib, had at least one detection in the 417 samples collected in the past 10 days.🛟😷🧪

Rare pathogens overview: Dials summarizing detections for all monitored rare pathogens. There were no detections for Mpox clade Ib, and a low number of detections for Candida auris, hepatitis A, Mpox clade II, and measles.

📊 WWSCAN Weekly Data:

EV-D68: EV-D68 is in the ‘Low’ category nationally and is not in season, but detections have increased at some plants in the Midwest and the West regions.

EV-D68: While EV-D68 levels are low nationwide, they have recently increased substantially in the Midwest, and a small amount in the West.

📊 WWSCAN Weekly Data:

Seasonal respiratory pathogens: Nationally, Flu A, Flu B, RSV, and HMPV are not in season (no “onset” of an event in wastewater). About 2%, 0%, 0%, and 0% of plants are still in onset, respectively. 🛟😷🧪

Seasonal respiratory pathogens: Line graphs showing concentrations of the four main seasonal respiratory pathogens (Influenza A, Influenza B, RSV, and HMPV) over the past year nationally and for four regions. Most currently have concentrations near 0.

📊 WWSCAN Weekly Data:

COVID-19 Variants: In sequencing data from a subset of WWSCAN sites from the week of Sep 20, 2025, we are seeing the XFG variant in orange make up approximately 85.2% of variants. Note sequencing data has a longer lag of 1-2 weeks after collection. 🛟😷🧪

COVID-19 Variants: A bar graph showing the proportions of SARS-CoV-2 variants measured in wastewater over time. Recently the XFG variant has become the most predominant variant.

📊 WWSCAN Weekly Data:

COVID-19: Nationwide, SARS-CoV-2 is in the ‘Medium’ category, with medium concentrations and a downward trend over the last 3 weeks. It appears we may have seen the peak of the summer wave in early September, but we will continue to monitor.🛟😷🧪

COVID-19 Line Graph: Line graph showing concentrations of SARS-CoV-2 in wastewater nationally and for four regions (Northeast, South, Midwest, and West) over the past year. Concentrations appear to have peaked in early September and may be decreasing.

📊 WWSCAN Weekly Data:

Respiratory weekly update: SARS-CoV-2 is in the ‘Medium’ category. All other respiratory viruses we monitor (RSV, Influenza A, Influenza B, HMPV and EV-D68) are in the ‘Low’ category nationwide. 🛟😷🧪

Respiratory weekly update: Dials showing that all seasonal pathogens (Influenza A, Influenza B, RSV, HMPV, and EV-D68) except SARS-CoV-2 are in the low category and not in seasonal onset. SARS-CoV-2 is in the medium category.

October is #RSV Awareness Month. Respiratory syncytial virus (RSV) usually causes mild, cold-like symptoms—and it can be serious for babies & older adults. It’s one of more than a dozen infectious diseases we monitor for in community #wastewater.
