Hello , I understand your concern. I am Dr. Arun Tank, infectious disease specialist, answering your concern. I advice you to test your self for the typhidot test. It is more sensitive and specific test than widal test. If this tests also shows you as positive than you can say you are carrier for Salmonella typhi. There is treatment option available like cholecystectomy for those patients who dont respond to the antibiotic therapy and remains as a carrier even after many treatment. Glad to answer your further concern. We wish you a best health at healthcare magic. Thank you, Dr. Arun Tank If you are satisfied with my answer rate me as five star and close the answer
