[The current situation with strongyloidiasis in the USSR].

The literary data available and our own observations served the basis for characterization on strongyloidiasis distribution areas in the USSR. They embrace the Caucasus, Middle Asia, the European part of the country up to latitude 55-56 degrees north in the Maritime Territory and the southern part of the Khabarovsk Territory. Intensive invasion foci in specialized hostel-type institutions, invasion importation from the tropics to moderate climatic zones and their role in the epidemic process are discussed.
