Norovirus remains a persistent public health issue in the United States, causing 20 million cases of infection each year and driving thousands of outbreaks in settings like schools, nursing homes, and hospitals. The virus spreads easily through contaminated food, surfaces, and close contact, making enclosed, high-density environments especially vulnerable. While norovirus circulates year-round, winter consistently exacerbates its spread, contributing to seasonal surges that lead to over 100,000 hospitalizations annually and disproportionately affect older adults, young children, and immunocompromised individuals.
