RESUMEN
A retrospective analysis of imported malaria due to military operations revealed the main regularities in the behaviour of Plasmodium vivax population and the relationships between the imported parasite and the native Anopheles species. High percentage of cases with protracted incubation was noted in soldiers after their home-coming; the clinical symptoms were often registered 7-12 months after return. No epidemic consequence of imported and introduced cases of tertian malaria in malariogenic areas was shown. The effect of mass drug administration in military contingents was proved to be low due to irregular use of drugs or their discontinuance. The import of carriers to malariogenic areas was found to cause a minimal risk of restoration and implantation of tertian malaria. The current epidemiological monitoring system was shown to be rather effective for maintaining the epidemiological prosperity in the country.
