The optimization of algorithm of laboratory diagnostic of Western Nile fever in territory of Russia

: The article deals with results of study of antigenic chiasms between viruses of Western Nile fever and tick-borne encephalitis using binding immunoassay applied to blood serum from patients residing in various regions of Russia. It is established that to get accurate laboratory diagnostic it is reasonable to apply the proposed algorithm of analysis in which alongside with binding immunoassay such differential criterion as positivity rate is to be implemented to speed up and simplify laboratory diagnostic of infections brought on by viruses of Western Nile fever and tick-borne encephalitis.
