[Strongyloidiasis prevalence in the subtropics of the Azerbaijan SSR].

The Berman technique was used in the authors' modification for strongyloidiasis survey of 18212 persons in various areas of Azerbaijan. It was stated that with the height increasing up to 500 m over the sea surface the infestation with strongyloidiasis increased and varied between 5.7 and 9.3 +/- 0.1%. At the height of 500-1500 meters the value decreased up to 3.5 +/- 0.1% and at the height of 2000-2400 meters was the lowest one (2.2 +/- 0.1%). The investigation revealed that the disease foci could appear not only in the plains or foothills but in mountainous and high-mountain areas of the Azerbaijan subtropics.
