If a person who was infected by Salmonella typhi begins to feel okay, does this mean he or she has stopped shedding the bacteria?

Not necessarily. Even if symptoms seem to go away, a person may still be carrying Salmonella typhi. If so, the illness could return and he or she could pass the disease to other people. In fact, if the person works at a job where he or she handles food or cares for small children, that person may be barred legally from going back to work until a doctor has determined that the person no longer carries any typhoid bacteria. Therefore, it's important for the person to consult a doctor to ensure that the bacteria no longer remain in his or her body.
