Norovirus—often called the perfect pathogen—is one of the leading causes of acute gastroenteritis outbreaks worldwide. Responsible for widespread illness across all age groups, it remains a major cause of childhood and endemic infections. Originally described as winter vomiting disease due to its seasonal surges, norovirus is infamous for its rapid spread, low infectious dose, and resistance to disinfection. In this episode of Transmissible: A Public Health Podcast, host and scientist Jessica Stahl breaks down what makes norovirus so uniquely contagious, how it wreaks havoc on cruise ships, in schools, and in prisons, and why it continues to be a persistent public health challenge.Citations and additional reading:Norovirus | Norovirus | CDCNorovirus (vomiting bug) - NHShttps://academic.oup.com/jid/article-abstract/205/11/1622/844989?redirectedFrom=fulltext Norovirus Disease in the United States - PMCEID_9-13_NorovirusInTheUnitedStates.pdfNorovirus: Facts and Reflections from Past, Present, and Future - PMC
