Concerning the Allocation of Emerging Natural Foci of the Currently Important Infectious Diseases in the West of Kazakhstan

Within the period of 2000-2011, in the West of Kazakhstan, identified have been five, previously unknown in the territory, natural foci of dangerous infectious diseases such as hemorrhagic fever with renal syndrome, Astrakhan spotty fever, Crimean hemorrhagic fever, West Nile fever, and tick-borne viral encephalitis. The reason is that key ecological factors for the persistence of the infections in the local biocoenoses occurred. It is characteristic that circulation of the agents of new infectious diseases is registered in the territory of the long-established natural plague and tularemia foci. Since 2000 and on, hemorrhagic fever with renal syndrome morbidity is registered in the Western-Kazakhstan Region on a regular basis. There is some evidence to identification of West Nile fever patients in the territory of Russia in 2012, which came from Kazakhstan. Based on the spatial distribution of the natural foci of various infections, Western-Kazakhstan Region has been subdivided into four areas. In order to provide for the effective prophylaxis of emerging diseases, it is essential that healthcare facilities and services dealing with infectious diseases are consolidated and reinforced, and epidemiological surveillance is improved with the current conditions in mind

Phylogenetic Characteristics of West Nile Virus Isolated From Culex modestus Mosquitoes in West Kazakhstan

West Nile virus is widespread in southern Russia, where the fever appears annually. Since Western Kazakhstan borders on southern Russia, we examined mosquitoes in this region for the presence of West Nile virus. Virus was detected in a small proportion of Culex modestus mosquitoes (3/239 pools) and isolates are related to strains from Volgograd, Russia. A screen for West Nile virus IgG was conducted and ~5% of the local human population tested positive.</jats:p
