Distribution Peculiarities of Certain Arboviruses in the Brazilian Part of the Amazon Basin,
Abstract
This report provides an analysis of findings from the study of certain arboviruses in the Brazilian part of the Amazon Basin with consideration given to physico-geographic regioning and the quantitative characteristic of a number of abiotic factors. The distribution of arboviruses transmitted by mosquitoes in a moderate climate depends basically on temperature factors. In equatorial and subequatorial climates, with constant high temperatures, the determining significance must belong to other abiotic factors. If, in the first case, the basic role is played by conditions determining virus development in carriers, then the leading role in the second case must belong to factors on which the existence of the carriers depend. An analogy may be drawn here with moderate climate viruses transmitted by ticks, such as the tick encephalitis virus. The areal virus in this case is essentially caused by factors determining the carrier areal. (Author)
