The performed studies showed, that morbidity of the population with echinococcosis substantially varies even within the boundaries of any administrative region and depends on a number of factors. According to climato-geographic conditions it is possible to single out three zones: arid zone (deserts, semi-deserts, salt-marshes) with minimal level of invasion of the population with echinococcosis; zone of semi-deserts and alpines with medium level of invasion; and zone of oases, valleys, middle-mountains and tugays--with high level of invasion. Among the risk group--cattle-breeders--2 subgroups could be singled out: steppe and mountains cattle-breeders, the risk of invasion in the laffer subgroup is substantially higher. It is necessary to include into the risk group also country housewives who are in constant contact with domestic animals, and schoolchildren who an in constant contact with dogs. The significance of aerogenic route of invasion is especially pronounced in children, and frequency of pulmonary form of echinococcosis has reached 50% and more. Besides studying the structure of morbidity and echinococcosis disease in relation to age, sex, occupational activities, for evaluation of epidemiologic conditions on territories it is advisable also to perform mapping of regions according to mass prophylactic examinations data with the use of serological reactions and US examinations, as well as to analyse epidemiologic conditions with the use of such criteria as indices of invasion, morbidity and detectability.
