Central Valley Respiratory Pathogens
This page displays HCVT wastewater data for the following infectious pathogens that primarily affect the respiratory system: SARS-CoV-2, Influenza A, Influenza B (IBV), Respiratory Syncytial Virus (RSV), Human Metapneumovirus (HMPV), Enterovirus D68 (EVD68), and Parainfluenza. Trends of the data through time indicate changes in the number of people in the community who are infected with the pathogen. Over time you will see this value rise and fall, indicating the rise and fall of the number of infections in the population served by each wastewater treatment plant. The results are reported to public health officials in Merced, Stanislaus and Yolo counties and to the public.
