Hi Thanks for posting your query Your concern is raised TLC (Leucocytosis) I will give you details but before we discuss little bit about your illness. To diagnose disease depend upon clinical features and investigations. Investigations itself vary according to tecnique. Malaria is diagnosed by y looking directly organism in blood with stain and by antigen these tests give you reliable positive test. Typhoid is diagnosed by clinical features, investigation Lecopenia(Low TLC), Wdal test, Antibodies IgG, IgM. Difficulty with these test results are reliablity especially when only one investigation is done. Only way to diagnosed Typhoid is complete background. I am not very sure about diagnosis of Typhoid of your illness. However about high TLC reflects body respose to insult in fact it is defensive mechanism and indication of infection most of the time BUT NOT always. During recovery raised TLC may be normal and rising TLC gives you clue there might be some complication of infection but not with certainity. There is no drug to lower the raised TLC in respose to infection. TLC count will come down gradually. If remain raised for weeeks or rising trends then look for complication or reinfection depeding upon your general well being. Hope this information will help you Take Care
