Norovirus, a highly contagious stomach bug that causes diarrhea and vomiting, is spreading across many states in the U.S., particularly in the Northeast, the Centers for Disease Control and Prevention (CDC) said in a report.
Norovirus outbreaks are expected to occur during late fall, winter, and early spring in the United States. Every year, it causes around 19 to 21 million cases of vomiting and diarrhea, resulting in 109,000 hospitalizations and around 900 deaths.
