Rise of Norovirus Outbreaks
Recent reports indicate a significant increase in norovirus outbreaks across the United States, with the Centers for Disease Control and Prevention (CDC) documenting 91 cases in just one week. This figure marks a notable rise from previous years, where similar weeks saw no more than 41 reported outbreaks. Due to the contagious nature of norovirus, many who contract it may not seek medical attention, leading to underreported cases. Public health officials emphasize the importance of handwashing with soap and water to mitigate the spread, especially before meals and after using the restroom.
