[Changes in the manifestations of tertian malaria on the territory of the CIS Nations].
The investigations made in the areas of residual endemics and the retrospective analysis of the prevalence of vivax-malaria revealed changes in its manifestations and in the functioning of parasitic systems in the past decades: selection of P. vivax strains with long-term incubation in the southern areas of the CIS and in the north of Afghanistan, which constitute a northern world areal boundary, increases in the periods of late manifestations up to 30-38 months, the minimal risk of renewal and implanting of malaria transmission in malarious territories where it was eradicated in the 1950s. The change in the habitance stimulates self-regulation for effective adaptation and species preservation. The pronounced adaptative properties of P. vivax which manifested themselves in altered changes of signs of vivax-malaria with short- and long-term incubations in the CIS should be borne in mind while planning and launching antimalarial measures in the endemic areas. These data may be useful in the comparative characterization of malarial parasitic systems in its various areas of spread.
