Norovirus Symptoms: Understanding the Impact of Food Contamination
Norovirus, often referred to as the “winter vomiting bug,” is a highly contagious virus that causes gastroenteritis, an inflammation of the stomach and intestines. It is the most common cause of acute gastroenteritis in the United States. Norovirus can be contracted from an infected person, contaminated food or water, or by touching contaminated surfaces. This article aims to provide a comprehensive understanding of the symptoms of norovirus and the impact of food contamination.
What are the Symptoms of Norovirus?
Norovirus infection can cause the sudden onset of severe vomiting and diarrhea. The virus causes your stomach or intestines or both to get inflamed. This leads to stomach pain, nausea, and other symptoms. Here are the most common symptoms:
- Stomach pain
- Nausea
- Vomiting
- Diarrhea
- Fever
- Headache
- Body aches
These symptoms usually appear 12 to 48 hours after first exposure to the virus and last 1 to 3 days. Some people may also experience severe vomiting, diarrheal dehydration, and abdominal pain.
How Does Norovirus Spread Through Food?
Norovirus can easily contaminate food because it is very tiny and infective. It can spread through food that is handled by a person infected with the virus, especially if they have not washed their hands thoroughly. It can also spread by consuming food or water that is contaminated with norovirus.
What Foods are Commonly Associated with Norovirus Outbreaks?
Shellfish, such as oysters, and fresh produce are often associated with norovirus outbreaks. However, any food can be contaminated with the virus during preparation if handled by a person infected with norovirus.
How Can Norovirus Infections be Prevented?
Practicing proper hand hygiene can help prevent the spread of norovirus. It is especially important to wash hands thoroughly after using the toilet and changing diapers, and before eating, preparing, or handling food. Norovirus can be found in your vomit or stool even before you start feeling sick. The virus can stay in your stool for 2 weeks or more after you feel better.
- Wash fruits and vegetables and cook seafood thoroughly
- Clean and disinfect contaminated surfaces
- Wash laundry thoroughly
Remember, norovirus can still be on objects and surfaces and still be infectious for days or weeks. Cleaning and disinfection are important to remove the virus.
What to Do if You Suspect Norovirus Infection?
If you suspect that you or a loved one has contracted norovirus, it is important to seek medical attention immediately. Dehydration can occur rapidly and can be life-threatening, especially in the very young, the elderly, and those with other serious illnesses. There is no specific medicine to treat people with norovirus illness. Rehydration is key to recovery.
