Biobot Analytics is a wastewater epidemiology company that analyzes sewage to provide wastewater surveillance data in the US for Covid-19 and Mpox. The data are updated weekly and accessible on demand. The data are also visible on the website with a report for each disease containing wastewater monitoring information at national and regional level. The effective virus concentration reported by Biobot is different from the results reported on CDC's Covid Data Tracker. Biobot normalizes to a fecal strength indicator measured in wastewater samples, whereas CDC results are normalized using flow and population.
