Milwaukee Health Department tracks respiratory viruses through wastewater

Milwaukee health officials are observing a steady increase in respiratory illnesses, including RSV and COVID-19, within the community. The Milwaukee Health Department is utilizing unique testing methods at the Zeidler Municipal Building to monitor these viruses.On Dec. 19, scientists at the Milwaukee Health Department began examining small wastewater samples from Jones Island to detect the presence of viruses such as flu A, flu B, RSV, and COVID-19. The testing process involves concentrating the virus in the wastewater and breaking them open to expose the RNA, according to Dr. David Payne.The wastewater analyzed originates from residential sources, and an automatic sampler collects samples every 15 minutes as the water enters the plant. These samples are then divided between the health department and the School of Freshwater Sciences for further analysis. This initiative allows the health department to track the spread of viruses, with recent findings indicating an increase in COVID-19 and RSV cases, though flu A and flu B remain less prevalent.Payne said the current respiratory season is relatively mild but warned of a potential increase in cases as the season progresses. The data collected is made available to the public through an online dashboard, providing daily updates. Payne emphasized the importance of this testing method in maintaining community health, as it enables individuals to take preventive measures such as improved handwashing, immunization, and masking.The public wastewater dashboard currently tracks flu, RSV, and COVID-19. Health officials aim to include whooping cough in the future, though resources are currently insufficient for this addition.
