My daughter is 5, she eats little meat, but otherwise had a diet of fruits, vegetables and carbs. She has become unwell in the last 24 hours, she had very dark circles under her eyes, yellowish complexion, running a temp between 37-39 over the last 24 hours. I have given paracetamol to control the temp. Her only other symptom is complaining of a sore bottom and occasional abdomen pain. Please can you advise, many thanks
