The creation of modern sewer systems solved critical sanitation issues in growing cities. Today, wastewater can even help researchers to detect and prevent disease outbreaks. This week on Health Wanted, host Laurel Bristow and guest Marlene Wolfe, PhD discuss the evolution of sewers and the role of wastewater surveillance in public health.  Bristow also answers your questions about timing your COVID and Flu vaccines, if alkaline water has any benefits, the proper way to brush your teeth, if Coca-Cola can prevent e. Coli, and of course - the Sick of the Week. For a full rundown on all the information shared in today's episode, take a look at the Show Notes. Have a question for Laurel?
