Norovirus Outbreak Reaches Alarming Levels
The United States is currently grappling with a significant surge in norovirus cases, commonly known as the stomach flu. This highly contagious virus has reached its highest levels in over a decade, prompting health officials to raise awareness about prevention and treatment. The Centers for Disease Control and Prevention (CDC) reported 91 outbreaks in the week of December 5, a stark increase from the average of 65 during the same period from 2012 to 2020.
Norovirus is the leading cause of foodborne illness in the U.S., responsible for nearly 58% of foodborne infections each year. It causes approximately 900 deaths, 109,000 hospitalizations, and a staggering 19-21 million cases annually. The virus spreads rapidly in group settings such as cruise ships, nursing homes, schools, and jails, earning it the nickname “cruise ship virus.”

Symptoms and Transmission
Norovirus symptoms typically include sudden onset of vomiting, diarrhea, nausea, stomach pain, body ache, headache, and fever. These symptoms usually resolve within one to three days, but the illness can be particularly severe for young children, older adults, and those with weakened immune systems.
“The illness is brief, but fierce.” – Dr. William Schaffner
The virus is highly contagious, requiring only 10 viral particles to cause illness. It spreads through direct contact with infected individuals, contaminated food or water, and touching contaminated surfaces. Common sources of outbreaks include leafy vegetables, fresh fruits, and shellfish.
Prevention and Treatment
Prevention is crucial in controlling norovirus outbreaks. Health experts emphasize the importance of good hand hygiene, particularly washing hands with soap and water. It’s important to note that hand sanitizers are not effective against norovirus.
“Good, repeated hand hygiene is the best preventive along with staying away from those who are ill.” – Dr. William Schaffner
Other preventive measures include thorough cleaning and disinfecting of surfaces, proper food handling, and avoiding close contact with infected individuals. There is currently no specific vaccine for norovirus, although Moderna is conducting trials for a potential vaccine.
Treatment for norovirus primarily focuses on managing symptoms and preventing dehydration. There is no specific medication for the virus, and antibiotics are ineffective as it is not a bacterial infection. Rehydration is crucial, and individuals should avoid coffee, tea, and alcohol.
As the norovirus outbreak continues to spread, it’s essential for individuals to stay informed, practice good hygiene, and take necessary precautions to protect themselves and their communities. By following these guidelines, we can work together to slow the spread of this highly contagious virus and minimize its impact on public health.
