Texas Study Detects All Major Cancer-Linked Viruses in Wastewater Across 16 Cities
1 articles · Updated · IndexBox, Inc. · May 20
Samples from more than 40 sites in 16 Texas cities collected between May 2022 and May 2025 detected every major known cancer-linked virus in wastewater, marking a first for community-level monitoring.
Researchers used a hybrid-capture sequencing assay that can screen for more than 3,000 human viruses, identifying HPV, hepatitis B and C, Epstein-Barr, cancer-related polyomaviruses and Kaposi's sarcoma-associated herpesvirus.
The three-year study found several oncogenic viruses rising after 2024, with HPV, Epstein-Barr and some polyomaviruses showing notable increases; the authors said the cause is unclear but may reflect more travel and post-pandemic social mixing.
HPV drew special attention: low-risk types were more common, but high-risk variants climbed sharply from late 2024 to early 2025, and HPV-16 appeared more often than HPV-18.
All nine strains targeted by Gardasil 9 were also found in wastewater, suggesting sewage surveillance could help gauge vaccine impact as oncogenic viruses are estimated to contribute to about 1 in 5 cancers worldwide.
If wastewater reveals a community's cancer virus secrets, what new public health strategies can be deployed for protection?
A post-pandemic surge in cancer viruses was found in Texas wastewater. Is the rest of the nation facing this invisible threat?
Cancer-Linked Viruses Detected in Texas Wastewater: New Study Tracks HPV, Hepatitis, and EBV Trends Post-2024
Overview
In May 2026, a landmark study led by Baylor College of Medicine and the University of Texas Health Science Center at Houston revealed groundbreaking findings about cancer-linked viruses in Texas wastewater. Researchers collected samples from over 40 sites across 16 cities between May 2022 and May 2025, covering a large portion of the state. Using an advanced hybrid-capture genetic sequencing technique, they detected all major oncogenic viruses, including HPV, hepatitis B and C, polyomaviruses, and Epstein-Barr virus. This innovative approach demonstrates how wastewater surveillance can effectively track cancer-causing viruses at the community level, opening new possibilities for public health monitoring and prevention.
