[|AI|]  Hello have gone through your question and understand your concern.  It appears to be symptoms arising from complication of typhoid fever involving gastrointestinal tract or a relapse due to antibiotic failure or resistance. To confirm relapse blood culture test negative is not sufficient as in 30-40% sensitivity to blood culture is low. Another method to test the relapse is testing antibodies in blood known as Tidal test or IGM antibodies against specific typhoid antigens. If all the above-mentioned test confirms no ongoing infection the symptoms of gastritis must be considered to be complication of typhoid fever which is not uncommon. Thank you.
