Molecularly imprinted polymers (MIPs) are artificial receptor ligands which can recognize and specifically bind to a target molecule. They are more resistant to chemical and biological damage and inactivation than antibodies. Therefore, target specific-MIP nanoparticles are aimed to develop and implemented to biosensors for the detection of biological toxic agents such as viruses, bacteria, and fungi toxins that cause many diseases and death due to the environmental contamination. For the first time, a molecularly imprinted polymer (MIP) targeting the bacteriophage MS2 as the template was investigated using a novel solid-phase synthesis method to obtain the artificial affinity ligand for the detection and removal of waterborne viruses through optical-based sensors. A high affinity between the artificial ligand and the target was found, and a regenerative MIP-based virus detection assay was successfully developed using a new surface plasmon resonance (SPR)-biosensor which provides an alternative technology for the specific detection and removal of waterborne viruses that lead to high disease and death rates all over the world.

Objective: This study aimed to assess the causes of the swimming pool-associated viral outbreaks in China and discuss the possible preventive measures for the outbreaks.
Methods: A systematic search was performed in 4 Chinese and English databases for studies investigating the swimming pool-associated viral outbreaks in China up to June 2024.
Results: 29 outbreaks were included in the review.

Groundwater is an essential drinking water source for humans. However, improper groundwater management leads to fecal contamination and waterborne diseases caused by viral pathogens. Therefore, this study aimed to investigate norovirus (NoV) contamination by conducting nationwide monitoring over five years (2019-2023).

The heightened public health risks associated with viral contamination in water have led to a strong emphasis on effective disinfection strategies. Ozone is a potent disinfectant widely employed for the inactivation of pathogens, yet comprehensive reports detailing the virucidal efficacy of hydroxyl radical (•OH) generated during ozonation are limited. The present research meticulously deciphered the role and influencing factors of •OH during ozone disinfection processes, elucidating how •OH enhanced ozone-mediated virus inactivation from both kinetic and molecular biological perspectives.

Background: Hepatitis E virus (HEV) causes acute jaundice and poses an important public health problem in low- and middle-income countries. Limited surveillance capacity and suboptimal access to diagnostics leads to under-reporting of HEV infections in affected countries, including Nepal. Serum antibodies against HEV are indicative of past infection.
