CLINICAL AND LABORATORY CHARACTERISTICS OF ACUTE RESPIRATORY VIRAL INFECTIONS ACCORDING TO THE INFECTIOUS HOSPITAL THE CITY OF NALCHIK

For etiological diagnosis of acute respiratory viral infections the improvement of clinical semiotics and searchfor epidemiological consistent patterns are advantageous. Aim the establishment of consistent patterns of the clinical picture of etiologically AIRS decoded by PCR method and validities of epidemiological signs in the Primorsky Krai in the recent period. The material of the study were medical history cases on 276 patients admitted to the infectious department of Primorye Regional Clinical Hospital №2 in the city of Vladivostok in 2014 with a diagnosis of AIRS. Results. In the etiological structure of patients there was dominated influenza (48.2%). Hereafter there were: rhinovirus infection (13.0%), parainfluenza (11.2%), metapneumovirus infection (9,8,5%), adenovirus infection (8.0%). The minimum share was presented by bocavirus (HBoV)) infection (5.16%) and the respiratory syncytial virus, (HRSV) infection (4.7%). There were established the most sensitive and specific symptoms of considered infections. There were revealed features of the seasonality and the age structure of the patients, affecting on the efficiency of diagnosis.

Vaccination Period

Of the acute respiratory viral infections in the farms of the Udmurt Republic, parainfluenza-3, respiratory syncytial infection, infectious rhinotracheitis, viral diarrhea are the most common. For the prevention of these cattle diseases, the inactivated combined vaccine Kombovak and Kombovak R. is used. Despite the widespread use of this vaccine, there is an ambiguous situation in the farms of UR and the percentage of ARVI incidence is extremely variable. Along with general economic factors, this can be explained using different schemes for the use of the vaccine. The work was carried out in the conditions of an industrial livestock complex located in the Uvinsky district of the Udmurt Republic. During the period of the work, 1,383 heads of cattle vaccinated with the Kombovak-R vaccine were monitored. Laboratory tests were carried out in the BI UR "Udmurt Veterinary Diagnostic Center" in the city of Izhevsk and LLC "Independent Veterinary Laboratory "Chance-Bio" in the city of Moscow. Determination of immunity intensity and retrospective serological diagnosis of ARVI was carried out by examining paired blood serum samples. Blood serum samples were taken from clinically healthy cows at the 6th month of pregnancy, i.e. at the end of the inter-vaccination period, as well as from unvaccinated calves with a live weight of 50-55 kg at the age of 17-18 days and after 21 days, respectively. When studying the preservation of post-vaccination immunity in cows, it was found that only two out of five studied animals have a protective level of antibodies to acute respiratory viral infections by the end of the inter-vaccination period. Serological screening of calves showed that antibodies to the pathogens of IRT, VD, RSI and PI-3 were determined in all samples. nevertheless, the titers of antibodies to ARVI pathogens differed significantly.

To identify the peculiarities of manifestation of epidemic process of influenza in 2016, and causes high morbidity and mortality in St. Petersburg, a comparative analysis of the incidence of influenza and acute respiratory viral infections, hospitalization and mortality in children and adults during the epidemic of 2016 in St. Petersburg and other 58 the observed cities of the Russian Federation. The epidemic of 2016 in St. Petersburg from other cities were characterized by a greater intensity: the duration of the epidemic; the incidence of the population on the peak (at 1.9 and 1.3%), within the boundaries of the epidemic in the city (7.7 and 5.4%) and the country (11.9 and 9,6%); shares admitted to hospital with a diagnosis of «influenza» among the whole population (17.1 and 14,0%); greater mortality from influenza among the whole population (3.3 tims), persons 15 - 64 (in 3 times) and 65 years and older (2.8 times). The low level of population immunity in Saint-Petersburg in the before the epidemic period and lower frequency of hospitalization of patients with influenza and ARVI among the population as a whole (2.4% and 3.6 percent), particularly children and persons over 65 years of age (2 times), could be the cause of high morbidity and mortality from influenza in St. Petersburg.
