Human respiratory and enteric viruses are responsible for substantial morbidity and mortality worldwide. Wastewater-based epidemiology utilizing next-generation sequencing serves as an effective tool for monitoring viral circulation dynamics at the community level. However, these complex environmental samples are often laden with other microorganisms and host genomic material, which can hinder the sensitivity of viral detection.

Article Synopsis
- The study focuses on using wastewater monitoring to detect SARS-CoV-2 in communities, particularly from October 2021 to October 2022 in Córdoba.
- Researchers collected 406 weekly wastewater samples and used real-time PCR to identify the virus and variants, enabling the creation of a viral activity flow map.
- The findings suggest that wastewater surveillance is a sensitive early warning system for COVID-19, identifying viral trends and hotspots even before clinical cases are reported, emphasizing its importance for public health responses.
Hepatitis E virus (HEV) is primarily transmitted via the fecal-oral route and is considered an anthropozoonosis. Genotypes with zoonotic potential (mainly HEV-3 and HEV-4) can be transmitted through the consumption of raw or undercooked pork, wild boar, deer meat, or processed products. This study aims to explore methodologies for processing meat samples to establish a protocol for HEV detection in meat.

This study aimed to monitor the circulation of Hepatitis E Virus (HEV) from wastewater samples collected during a six-year period and compare these results with clinical surveillance in the central region of Argentina. From 2017 to 2022, 1008 raw wastewater samples were analyzed, including four wastewater treatment plants from four cities (n=319), and 7 local neighborhood collector sewers in Córdoba city (n=689).

Segment 1 encodes the capsid protein and segment 2 encodes RNA-dependent RNA polymerase. They exhibit high genomic heterogeneity and infect a wide range of vertebrate hosts, including humans.
