Will Widal Test after positive resul treatment in Typhoid?

Yes, a Widal test may still show positive results after successful treatment of typhoid fever. The Widal test detects the presence of antibodies against Salmonella Typhi, the bacterium that causes typhoid fever. These antibodies can remain in the blood for several weeks or even months after the infection has been cleared, even after successful treatment.

A positive Widal test result after treatment does not necessarily mean that the person is still infected with typhoid fever. It is important to interpret the test results in the context of the person's clinical symptoms and other laboratory findings. A negative Widal test result, however, strongly suggests that the person has successfully overcome the infection.

In some cases, a person may experience a relapse of typhoid fever after initial successful treatment. In such cases, the Widal test may again become positive. Therefore, it is important for individuals who have been treated for typhoid fever to continue to monitor their health and seek medical attention if they experience any symptoms suggestive of a relapse.
