The term seroconversion describes the development of antibodies in previously negative patients or in groups of a given population in a defined time frame as a result of a natural infection or by application of a vaccine. The term “rate” confers on the number of people involved when, e.g., controlling vaccination programs. In the case of  Toxoplasma gondii infections of previously noninfected pregnant women, a seroconversion may be a sign that the fetus might be endangered. In these cases chemotherapy should be discussed depending on the antibody level and the stage of gravidity.
