Characteristics of Norovirus are as follows:
- Sudden onset of vomiting
- Watery diarrhea
- Stomach cramps
Some other less common symptoms include headaches, fever and muscle ache. If the muscle and body aches and pains are persistent and severe, this could be a sign that the condition is worsening.
In general, the symptom of extreme nausea and vomiting does not exceed 24 hours, while other symptoms last from 24 – 60 hours.
Acute diarrhea without vomiting may also occur. Not every case of Norovirus is the same, symptoms may present one way with one child, and a different way with another. It is important to keep a close eye on your child. If they seem to exhibit classic symptoms, it is likely that they have contracted the virus.
