HI, thanks for using healthcare magic
Gastroenteritis causes symptoms such as
abdominal pain, fever, nausea, vomiting and diarrhoea. Some or all of these symptoms are present.
If she is still having loose stools then the infection can still be transmitted.
The risk of transmission is significantly reduced by careful handwashing since the infection can be passed in this way.
At her age, you have to be very careful with her fluid management because children are at risk of
dehydration. Her fluid losses need be replayed, oral rehydration fluid is the best option.
Dehydration is associated with decreased urination,
drowsiness,
increased heart rate, dry skin/mouth, lack of tears.
If any of these are seen then it would be best visit a doctor.
I hope this helps
