Summary: Week of 7/5/25
Biobot’s national wastewater network shows that COVID-19, influenza A & B, and RSV are holding steady at very low levels in week 27 (through July 5, 2025). Though, we are starting to see an uptick in COVID-19 activity in the West and South. National hospitalizations for COVID-19 and RSV continue to hold steady at low levels, currently at 0.8 and 0 per 100,000 people in week 26 (through June 28, 2025). Flu hospitalizations rates have not been updated on the CDC website since May 3rd.
The Bottom Line: All major respiratory viruses are low right now, but we are starting to see some signs that COVID-19 is beginning to increase.

Footnotes:
We continue to monitor the evolving H5N1 influenza virus situation, and can now test samples specifically for H5 (including H5N1) — see our blog here and please reach out to hello@biobot.io if interested. A quick reminder that Biobot’s influenza A assay described in this report includes the H5N1 influenza subtype, which is an influenza A virus, but does not distinguish between the different subtypes of influenza A (e.g. H5N1 vs H1N1). We will share any important updates as we have them via Bluesky and in the risk reports.
Wastewater data from Biobot Analytics for RSV, influenza, and SARS-CoV-2 are through July 5, 2025 (MMWR week 27). Clinical data for RSV, influenza, and COVID-19 are from the Centers for Disease Control and Prevention. Updates to clinical data are through June 28, 2025 (MMWR week 26).
