Hi and welcome, Let me help you with some information on Typhoid fever. It is an infection caused by an organism called Salmonella typhi. This bacteria is found only in humans and not in other animals. It is very commonly found on contaminated food, which once ingested can cause the infection. This food can be contaminated by either the food supplier or the consumer, due to bad hygiene. Some people are carriers and are a threat to the community if they deal with food handling. Next, you need to know that this organism is commonly found in the human intestine and it colonizes there, and if a timely diagnosis is made after at least a serological test (Widal) and a proper course of antibiotics is taken by the patient, typhoid should not recur. Although it does in many different cases. This depends on whether an accurate diagnosis of typhoid was made the first time, there are cases when a patient has been inaccurately diagnosed with typhoid (without a serological test) and been prescribed a dose of antibiotics to treat typhoid, but the second time when the patient actually returns with typhoid, it is mistaken as a recurrence. I hope you have been accurately diagnosed the first time, and also that you have completed the advised duration and course of medication. Normally it is prescribed for a duration of 14-15 days. As you are currently positive to widal, you do have typhoid and need to take a course of antibiotics which will best eradicate the causative agent, but obviously under supervision of your physician. I hope this helps. Do get back to me for more information if you need it. Wishing you a speedy recovery and good health.
