<s>[INST] My 3 1/2 yo has red swollen tonsils, high fever 103+ unmedicated (101 medicated), headache and light sensitivity. Went to pedi today, Flu A&B negative, strep rapid test negative, waiting on strep DNA test. The light sensitivity started after pedi visit, so wasn t considered at the visit. My older daughter just finished a round of abx for strep a few days ago. We thought the strep test on little sis would be positive for sure. Also, 3 1/2yo is missing some vax due to a rxn at 15months. Is there anything else on the radar that we should consider testing for? [/INST] Hi,I don't think you should consider any further testing as of now. There is a possibility of bacterial infection but a greater possibility of viral in origin. a full course of antibiotics , and paracetamol round the clock would take care in few days time. if no response then further testing would be advisable.regards. </s>
