[An assessment of the helminthiasis situation in Belorussia by the dynamics of the mean multiyear indices of population morbidity].

The study of population morbidity with helminthiasis prevalence in Byelorussia has revealed 11 nosological entities and has established that in 99.9% these were cases of ascariasis, trichocephaliasis and enterobiasis. In 1981-1989 dynamics of ascariasis and trichocephaliasis morbidity was characterized by a marked tendency towards its decrease, while there was a tendency towards moderate growth in enterobiasis morbidity. The values of the (intensive) rates of helminthiasis morbidity during the examination of hundreds of thousands people does not considerably depend on the fluctuations of the number of persons examined on the presence of helminths. To elaborate systems for epidemiologic surveys of helminthiasis it is necessary to increase the volume and improve the quality of information on the morbidity rates.
