[Typhoid fever imported from the tropic in Poland].

We present three cases of typhoid fever imported to Poland from India in the beginning of the year 2006 treated in our Zoonosis and Tropical Medicine Department. Two of them, with mild course of the disease, were vaccinated with Typhim Vi vaccine, the third didn't obtain any, and had very heavy, almost classical course of the disease. All of them behaved in India in improper way, probably also because were convinced they were protected by the vaccine. We emphasize that proper prophylaxis against typhoid fever for travelers should consist of vaccination with two vaccines, oral Ty 21a and parenteral Typhim Vi and it doesn't release travelers from avoiding risky behavior.
