What is Norovirus?

Norovirus is the leading cause of acute gastroenteritis, an inflammation of the stomach and intestines. The virus spreads through contaminated food, water, surfaces, and close contact with infected individuals. While norovirus illness is typically short-lived, it can be severe– especially for young children, older adults, and those with weakened immune systems. Symptoms of norovirus typically appear within 12 to 48 hours after exposure to the virus. The early onset is often sudden, and symptoms can escalate rapidly, leaving affected individuals weak and unwell.

The Earliest Symptoms of Norovirus

Here are some of the earliest symptoms reported at the onset of a norovirus infection:

1. Nausea: A sense of queasiness or unease in the stomach is one of the first signs of norovirus. Nausea may develop suddenly and can range from mild discomfort to an overwhelming feeling that leads to vomiting.
2. Vomiting: Norovirus often triggers intense and frequent vomiting, which is one of its hallmark symptoms. Vomiting can appear early in the illness and is a key way the virus spreads, as it can contaminate surfaces and surrounding areas.
3. Diarrhea: Watery, non-bloody diarrhea is another early symptom of norovirus. Diarrhea often begins alongside or shortly after nausea and vomiting, contributing to dehydration if fluids are not replaced promptly.
4. Stomach Cramps: Cramping or discomfort in the abdominal area is a common early symptom. These cramps are caused by the virus’s effect on the gastrointestinal tract and can range from mild to severe.
5. Low-Grade Fever and Chills: In some cases, people may experience a slight fever, body aches, or chills in the early stages of a norovirus infection. While these symptoms are less common, they can accompany gastrointestinal distress.

When To Seek Medical Attention

The sudden onset of nausea, vomiting, and diarrhea within 1 to 2 days of potential exposure is a strong indicator of norovirus. If symptoms appear after attending an event, eating at a restaurant, or spending time in a crowded setting, it’s important to consider norovirus as a possibility. Some norovirus infections resolve on their own within 1 to 3 days, however there are instances when seeking medical attention promptly is essential. Consult a healthcare provider if you have symptoms that persist longer than 3 days, if you experience dehydration, or if you experience particularly intense symptoms.

Preventing The Spread of Norovirus

• Wash hands thoroughly with soap and water, especially after using the restroom or handling food
