8m vry low neutrophils &high;

Hi. My 8 month old son had high fever of 103 degrees. Went to Pead and gave him the medicines babygesic and ibugesic. So it was going down when given medicine and peaking high at night. The fever didn't subside so doctor gave him antibiotics Macpod. With that the fever is down to normal temperature.been one day without fever. also doctor suggested cbc where it shows very low neutrophils and high lymphocytes. Doctor said it's both bacterial and viral infection. Also he is not breastfeeding properly but eating.. drooling as well. He is playing sometime and get very fussy and cry. Looks like throat pain. I'm worried if this is something serious as neutrophils count is only 6.2 % ( range 17-44). Dengue -typhoid negative CRP -3.24 ESR- 9 Attaching the CBC for the reference.
