What can cause prolonged fever?
Patient: i am 30 years having fever since 4 days  i consult to  a doctor and having one antiboitic and cetamol... but the fever is still there and today i went for blood test ,,, the test was WBC count which was low than normal... is it typhoid as malaria test was negative Doctor: Hi thanks for asking question.Here your CBC count reveal low WBC count , so yes it might be typhoid if present with abdominal pain.For confirming it blood culture or widal test can be done.But if typhoid comes negative then search for other causes has to be done according to complete history and physical examination.If in severe infection bone marrow is involved then it get suppressed and present with low wbc cpunt.Certain drug can also lead to low WBC count.TB, HIV, Aplastic anemia, radio or chemotherapy also lead to low wbc .So detailed work up necessary.I hope you can understand my concern.
