There are considered problems of epidemiology and clinical presentation of enteroviral infections in the territory of Primorsky Krai. Among the hospitalized adult patients during the period from 2006 to 2012 persons aged from 18 to 39 years (49,3%) prevailed. The main clinicalforms of enteroviral infection (EVI) are a "minor" illness (55.6 %) and serous meningitis (21.7 %). In the study of a series of cytokines the differences in patients with the "minor" illness and serous viral meningitis have been identified. From 2009 to 2012 the incidence of EVI has a sporadic seasonal character (previously there was epidemic seasonal incidence). Adults are mainly affected. The epidemic process is formed owing to corporate and school-university types, with a dominated contact-community-acquired pathway of transmission. The dramatic shift in the nature of EVI rate in recent years, likely due to the exchange of the leading modes of transmission pathway, nutritional, which determined the carrying non-typical for the Primorsky Krai pathogen variants (ECHO - 30), by the contact-community-acquired pathway of transmission.
