My daughter is 5.11 yrs old. She has had fever from last week Thursday. The temp was almost 102 to 103 for the first 2 days. Comes to normal after meftal. The last 4 days temp has been fluctuating. It comes to normal abd then after 7 hrs hours back up, highest being 100.7 to 101. Tom is the 7th day. She has infected tonsils and viral conjunctivitis on one eye as well. I have been hearing most kids in chennai are going through this viral bout now. She's relatively active, eating lesser than usual. The meds she's on are refzil_0 3rd day today, montair lc, brozedex, seroflow and allegra nasal spray. Once in 7 hrs paracetamol and meftal p only in the night.  Should I take blood tests for dengue or others or can I wait. Please advise. I'm very anxious. Her weight is 22.3. She has no vomiting rash diarrhoea or anything else. Thank you.
