Sewage Surveillance: Watching Wastewater for SARS-CoV-2
Detection methods for the SARS-CoV-2 virus often involves reactive measures - such as testing individuals based on suspected exposure and/or symptomology. Time from initial individual exposures to testing results can be days or even weeks. Monitoring viral RNA particles in sewage may lessen the time from exposure to detection. Wastewater sewage surveillance is one method being explored as a way to examine a population directly, as well as trend prediction, and potentially estimate numbers of infected individuals in a population.
