A joint study by Baylor College of Medicine and the University of Texas has detected an increase in oncogenic viruses in wastewater after 2024. The resumption of travel and the end of social distancing would have reactivated the circulation of pathogens such as HPV-16 and HPV-18, responsible for more than 70% of cervical cancers. Wastewater analysis allows tracking asymptomatic infections for years, offering a window for early prevention.
Epidemiological surveillance: sewer technology against cancer 🧬
The wastewater analysis technique was already used during the pandemic to track SARS-CoV-2, but it is now applied to oncogenic viruses. Researchers can detect viral genetic material in community samples, identifying high-risk variants like HPV-16 and HPV-18 before clinical symptoms appear. This method allows monitoring population health without invasive tests, and facilitates preventive interventions such as targeted vaccination campaigns. The study published by the Texas scientists highlights the potential of this tool to reduce the incidence of cancers associated with infections.
The return of HPV: from the sewer to the doctor's office 🦠
It seems that while we were leaving the mask at home, oncogenic viruses were taking advantage to do post-pandemic tourism. Now it turns out that what we flush down the toilet can tell us more about our health than many medical check-ups. If HPV-16 and HPV-18 are already lining up in the pipes, at least scientists now have the map of their route. Who would have thought that the sewage system would become the new early warning service against cancer.
