In a child running fever
for about a month now needs a careful evaluation and medical check up.
It is important to identity the focus of infection in all children with fever.
Fever with vomiting
can occur in girls suffering from urinary tract infection
even though you may think it is sounding weird.
If it is getting worse, it means the infection has been progressive.
A complete blood count
and urine test will help in clarifying the picture.
In the meantime, ensure that the temperature is brought down with paracetamol
in right dose given every 6th hourly.
Also keep her well hydrated with plenty of clean distilled water. She must have a good urine output at all times.
Wishing your child a speedy recovery.
