Hi, dear I have gone through your question. I can understand your concern. Your son has high grade fever. His malaria test is negative. His total count is very high with high neutrophil count so it suggest some bacterial infection. He should take broad spectrum antibiotics like cephalosporins. Wait for culture report and start antibiotics according to culture reports. Chances of typhoid is low because in typhoid total count is low. High total count suggest other bacterial infection. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
