MiWaGen: Twist-enriched Wastewater Virome from Finland 2020-21 and 2024-25
We conducted sequencing-based analysis on 120 composite untreated influent wastewater samples from five major cities across Finland, collected in two 12-month sampling periods, during 2020-2021 and 2024-2025. Analyses led to the detection of diverse virome, with over 600 distinct species detected. Characterization of the human virome revealed a shift towards persistent viruses during pandemic restrictions.
