Enteric viruses, such as poliovirus, are a leading cause of gastroenteritis, which causes 2-3 million deaths annually. Environmental surveillance of wastewater supplements clinical surveillance for monitoring enteric virus circulation. However, while many environmental surveillance methods require liquid samples, some at-risk locations utilize pit latrines with waste characterized by high solids content.

Numerous studies of UV-induced inactivation focused on nonenveloped viruses. Little is known about UVC action on enveloped viruses across UVC wavelengths.

- - Environmental surveillance of poliovirus (PV) is crucial for global eradication efforts, with the bag-mediated filtration system (BMFS) enhancing effectiveness compared to the WHO's two-phase grab method.
- - The study improved the BMFS for use in wastewater and surface waters in Nairobi by modifying aspects such as bag size and filter design to increase efficiency.
- - The enhanced BMFS can concentrate larger volumes of water (3-10 L down to 10 mL), resulting in a 6-20 times greater effective volume assayed than the WHO method, potentially reducing false-negative results and simplifying logistics for virus detection.
