A point of care device, comprises a chamber configured to contain a swab. Once a swab is loaded, the device introduces a buffer into the chamber, then lyses cells collected by the swab. Probes such as padlock probes target a specified content such as a virus (e.g., SARS-CoV-2 RNA) and will bind, splint ligate, and rapidly isothermally amplify (e.g., using rolling circle amplification). Also described is a wastewater pathogen tracking dashboard and schema for detecting and tracking pathogen spread within communities by monitoring microbial and viral RNA.
