[Verification of dengue fever cases imported to the territory of the south Far East.]

1. The most reliable method of rapid verification (in 100%) the primary infection DENV was the comprehensive determination of antigen and antibodies of the IgM class; 2. With antigenemia, blood should be used to isolate the virus, as well as to diagnose the disease by PCR and to establish the genotype of the DENV; 3. When using only PCR to indicate Dengue virus, a significant proportion of the disease cases will not be diagnosed.
