High grade ever running or 3 days in succession requires a careful search of the focus of infection. In a girl child with such high spiking fever, always rule out a urinary tract infection
as it can present with vomiting
episodes. Malaria and typhoid are other possibilities.
Thinking only on lines of viral infection can delay the diagnosis. Get her complete blood count
along with urine test.
Bring down the fever with syrup paracetamol
to be given 6th hourly in the right dose and also tepid sponging if fever does not subside. Children of this age are susceptible to febrile convulsions
and thats why fever should always be taken care.
Wishing your child a speedy recovery.
