Hello.. Welcome to HCM.. I am Dr Jigar( infectious disease specialist). I understand your concern but you have not provided many important information like description of your symptoms. When did your fever started, what was the titre of widal test, did it increased on repeat testing? I also want to inform you that single widal is not much informative. Also blood culture is very useful in initial period of infection before starting the treatment. In your case blood culture is showing staph.hominis which is commonly found normally on our skin. So it tells contamination of blood sample by skin flora and should not be considered. My advice to you is repeat widal test and look for rise in titre. Meanwhile your doctor can start antibiotics(if he feels) according to your symptoms. I hope this will help you. Wish you rapid recovery. Regards.
