title: [Seasonality of toxoplasmosis].
abstract: The indices of seasonal changes in the proportion of population allergopositive to toxoplasmosis were determined by analyzing the results of intracutaneous tests made in 61,324 pregnant women in Novokuznetsk between 1964 and 1974. Indices exceeding the average monthly level were registered in March-July and in September-October. Taking into account the modal term during which allergization develops in a patient from the moment of toxoplasmic invasion, a high risk of toxoplasmosis infection is likely to be present mainly during winter and spring (December-May), as well as summer (July-August) periods. Researchers should pay attention to the nature of the seasonal prevalence of the epidemic process of toxoplasmosis.
