IMPORTED DENGUE FEVER CASES IN THE KHABAROVSK TERRITORY

Fifteen imported Dengue fever cases were registered in Khabarovsk in March 2012 to January 2013. The patients sustained its moderate uncomplicated classical form, which was indicative of the primary infection of the tourists with Dengue virus. This was confirmed by the flavivirus RNA and Dengue virus antigen being isolated in the acute period of the disease and by IgM detected in the course of the disease. The main clinical and laboratory manifestations of the disease are high fever, severe intoxication, exanthema, polylymphadenopathy, leukopenia, thrombocytopenia, and plasmocytosis in the hemogram. The emergence of a great number of cases of Dengue fever importation to the Far East in 2012 reflects the unfavorable epidemiological situation associated with this disease in the countries of Southeast Asia. If tourists coming from this region are feverish, they should be examined for Dengue fever. The timely detection and valid diagnosis of the disease and its (classical, hemorrhagic) forms allow the development of severe complications and poor outcomes to be prevented.
