[The landscape-malariological characteristics of the territory and the epidemiological features of malaria in the Kabardino-Balkarian Republic].
Malaria was widely spread in the Republic of Kabardino-Balkaria in the past, but its incidence rates varied in different areas, which depended on natural and climatic and socio-economic factors. Malaria was transmitted in the whole republic, except for its high-altitude areas. Malaria was most common in the lowlands. In the season of malaria transmission, P. vivax, the causative agent of the disease, can made 4 cycles in the plain, only 3 and, occasionally, 4 cycles in the piedmont. The climatic features of the republic give rise to the emergence of as many as 5 vector generations in the lowland in the epidemiological period. The peculiarities of malaria in the republic were seasonal fluctuations of malaria manifestation among the population with a winter interval of its transmission. The monthly distribution of malaria patients was typical of the "southern" type of a morbidity curve. The curve was two-peaked: the first peak was characterised by a small elevation of morbidity in March and April with the maximum in May and June, the second peak was characterised by a more drastically significant elevation in August and September owing to the varying proportions of two types of vivax malaria: that with long- and short-term incubation (30% against 70%). The bulk (as high as 70%) patients with malaria was recorded in its transmission season (June to September), in the period of the highest activity and the maximum size of vectors. In the republic, tertian malaria was mainly detected, cases of quartan and tropical malaria being registered.
