[The division of the territory of Azerbaijan into districts by hydatid echinococcosis]

The epizootiological and epidemiological stratification of the territory of Azerbaijan on hydatid disease was made. Four zones were identified as low, moderately, highly and extremely endemic. These zones are differentiated from their climatic and social conditions for echinococcosis distribution, human incidence and prevalence, canine and ovine number and prevalence, and the time of survival of echinococcus eggs in the soil. The most intensive disease control measures are recommended in mountainous regions of the Small Caucasus.
