Norovirus (Vomiting Bug)

Key Points

Overview

Norovirus, often called the winter vomiting bug, is a very common stomach infection. It causes sudden and unpleasant symptoms like vomiting and diarrhea. While it can occur any time of year, it's known for spreading quickly, especially in crowded environments.
