Hi I did review your concern. WIdal test is done for typhoid infection. THe ideal treatment is cefexime or cefepime tablets for 7-14 days or ciprofloxacin BD for 10-14 days. There are few resistant strains that require higher antibiotics. but that requires stool or blood culture and antibiotic sensitivity testing which can be done after a failed course of this antibiotics. Also remember that the serum antibody counts go slowly over 1st week so the patient might be treated but the antibody might remain and hence it can cause a false positive in such a way. I Hope this helps. Wish you all the best Thank you for choosing healthcaremagic
