question: My son (14) returned from school yesterday with ache behind the eyes, headache and feeling like he wants to vomit. He ate and drank well yesterday however today after returning from school barely ate but drank plenty of fluid and went to bed. We are African and reside in the UK. I ve heard recently about the prevalence of West Nile flu in the UK. Please advise on whether this requires urgent hospital visit. Lastly he does not have a fever but is very tired.
