Typhoid Fever, Carrier

The chronic typhoid carrier state can occur following symptomatic or subclinical infections of Salmonella typhi. Among untreated cases, 10% will shed bacteria for three months after initial onset of symptoms and 2-5% will become chronic carriers. The chronic carrier state occurs most commonly among middle-aged women.
