[|Human|] Hi, I wish to employ a cook but his pre employment screen showed a positive widal count for typhoid and negative stool culture. He has had antibiotics for 10days and his repeat widal test is now normal. Can I be assured that he is clear and employ him as a cook or does he need further tests?
[|AI|]  Hello, Thank you for your contact to Chat Doctor. I understand your concern. If I am your doctor I suggest you that tidal test is not a confirmatory test there are chances of false positive and negative result. Ty phi dot is very reliable test than tidal you can think for it. Salmonella type bacteria can remain hidden in the gall bladder and can cause relapse. If possible you should do a gall bladder culture. Once a gallbladder culture is negative you can recruit cook as confirm negative person. I will be happy to answer your further concerned can contact me. Chat Doctor. Infectious disease specialist. Thank you.
