A common stomach bug, norovirus, is on the rise in the US, with 91 outbreaks reported in the week ending December 5, according to the US Centers for Disease Control and Prevention (CDC). This surge in cases highlights the importance of understanding how norovirus is spread, what symptoms to expect, and how long they can last.
Dr. Leana Wen, an emergency physician and clinical associate professor at George Washington University, shares her expertise on preventing the spread of norovirus. “Norovirus is the leading cause of foodborne illness in the US,” she explains. “It results in over 2.2 million outpatient medical visits each year.”
So, how is norovirus spread? Wen notes that it can be transmitted through direct contact with an infected person or contaminated surfaces. This means sharing food or drink with someone who has norovirus, touching a surface that an infected person touched and then touching your mouth, or contracting the virus through tiny drops of vomit or fecal material.
Symptoms of norovirus include nausea, vomiting, diarrhea, stomach cramps, fatigue, low-grade fever, chills, headaches, and muscle aches. While most people recover within one to two days, some may become severely ill due to dehydration.
To prevent the spread of norovirus, Wen advises people to wash their hands well with soap and water before eating and after using the bathroom, especially if someone in the household has been infected. She also recommends regularly washing surfaces that may be contaminated with the virus. Additionally, she suggests not preparing food or serving meals while experiencing gastrointestinal symptoms.
In terms of food safety tips, Wen emphasizes the importance of:
* Avoiding raw milk and undercooked meat
* Using internal thermometers to ensure cooked foods reach a safe temperature
* Washing vegetables and fruits well before consumption
* Keeping perishable food at a safe temperature
By following these guidelines, individuals can reduce their risk of contracting norovirus and other gastrointestinal illnesses.
For those who suspect they may have norovirus or are experiencing severe symptoms, Dr. Wen advises seeking medical attention if:
* Blood in the stool is present
* High fevers or shortness of breath
* Symptoms persist longer than two days
By understanding how norovirus is spread and taking preventative measures, individuals can help reduce the risk of transmission and alleviate the impact of this common stomach bug.
