title: [Dynamics of typhoid-paratyphoid infection morbidity in Chimkent Province].
abstract: The study of the time course of typhoid-paratyphoid infections in the Chimkent region for the period of 1944-1979 has revealed the periodicity of their rises (falls) repeating every 2-4 years. Since 1964 the tendency towards the decrease of morbidity has been observed. The annual rate of this decrease is 4.9%. Periodic changes in the annual level of typhoid-paratyphoid infections do not depend on the temperature of the air and the seasonal number of winged flies. There is a pronounced direct correlation between the annual morbidity level and the frequency of summer precipitations, this correlation being more pronounced during the first 2 summer months.
