Baylor Study Detects All Known Cancer-Causing Viruses in 16 Texas Cities' Wastewater

Samples from more than 40 sites in 16 Texas cities collected between May 2022 and May 2025 detected all known oncogenic viruses, including HPV, hepatitis B and C, Epstein-Barr virus and cancer-linked polyomaviruses.
The Baylor-led team used hybrid-capture genetic sequencing through Texas's TexWEB network, a method that can identify more than 3,000 human viruses from sewage without testing individuals.
Roughly one-quarter of Texas's population was covered, and researchers found several oncogenic viruses increased over the three years, with HPV, EBV and some polyomaviruses rising sharply after 2024.
HPV tracking showed low-risk types were more abundant overall, but high-risk strains also climbed from late 2024 into early 2025; HPV-16 remained more common than HPV-18, and all 9 Gardasil-targeted types were detected.
Researchers said the findings could support earlier public-health action and help gauge whether vaccination programs are reaching communities before virus-linked cancers emerge years later.
Beyond early warnings, could mapping viral hotspots in wastewater data help predict future cancer clusters?

Texas Wastewater Study Uncovers Rising Levels of Oncogenic Viruses: Implications for Cancer Prevention and Public Health Strategy
Overview
In May 2026, a pioneering study by Baylor College of Medicine and the University of Texas Health Science Center at Houston made a major breakthrough by using wastewater surveillance to detect and track all major cancer-causing viruses in Texas communities. This innovative approach provided, for the first time, a comprehensive view of the prevalence of viruses like HPV, HBV, HCV, EBV, KSHV, and polyomaviruses at the community level. By analyzing wastewater, researchers could identify which viruses were present and monitor how their levels changed over time, offering a powerful, non-invasive tool for public health surveillance and early intervention.
