A clearer indicator for trends in a community’s COVID-19 infection rate may come from its wastewater. Rock County Environmental Health Director Rick Wietersen says more and more communities are now testing wastewater for virus levels. Wietersen says a community’s level of infection can be found from just one test. He says the virus can be found with this method even before someone becomes ill. He says this is not a substitute for human testing, but it can indicate early trends for an entire community.
