Paddleboarding in infected waters? Answering patient questions.
In this episode, we explore a patient’s worry about paddle boarding in a pond tested positive for E. coli. The discussion extends beyond individual risks to the challenges in acquiring and communicating quantitative risk data, using the framework of Quantitative Microbial Risk Assessment (QMRA). Through examining studies and real-life examples, this episode delves into the complexities of risk assessment and the need for improved health communication standards. Join us as we navigate these murky waters and reveal why sometimes, opting for caution might be the best advice.
