My son is having loose bowel movement with on and off fever since last night and now he is also vomiting. He feels dizzy and a bit weak. No stomach or abdominal pain. He had urinalysis and result is within normal reference interval but i noticed protein is 30 mg/dl (1+) - is this normal? He also had CBC and result is WBC 12,720 mm3 (4800-10800 normal range), LYMPHOCYTES is 11% (19-48 normal range), STABS is 13% (2-6 normal range). The rest of the CBC count is within normal range. He had fecalysis and result is PUS CELLS 4-8 hpf, RBC 0-1 hpf and no parasites seen. Based on these data, what is the sickness of my son? Thank you
