The main symptoms of norovirus infection are vomiting, diarrhea, and stomach cramping.
Understanding Norovirus Symptoms
Norovirus is a highly contagious virus that causes gastroenteritis, an inflammation of the stomach and intestines. It is often mistakenly referred to as the "stomach flu," though it is not related to the influenza virus. Symptoms typically develop quickly, often within 12 to 48 hours after exposure.
Based on the provided information, the symptoms of norovirus are categorized as common and less common.
Common Norovirus Symptoms
The most frequently reported symptoms of a norovirus infection include:
- Vomiting: This can be sudden and forceful.
- Diarrhea: Often watery.
- Stomach Cramping: Pain or discomfort in the abdomen.
These symptoms can lead to dehydration, especially in young children and older adults, so staying hydrated is crucial.
Less Common Norovirus Symptoms
In addition to the primary symptoms, some individuals may experience other less frequent symptoms, such as:
- Low-grade fever or chills
- Headache
- Muscle aches
These symptoms are generally less pronounced than the vomiting, diarrhea, and stomach cramping.
