CLINICAL AND EPIDEMIOLOGICAL CHARACTERIZATION OF INFLUENZA IN THE KRASNODAR KRAI: FIVE-YEAR MONITORING

The aim is to characterize of some clinical and epidemiological indicators of influenza in the Krasnodar Territory over a fve-year follow-up period (2014–2018).
Materials and methods. The results of the monitoring of 2014-–2018 were used. for the circulation of influenza viruses in the form of selective studies of influenza viruses in biological material using the polymerase chain reaction, virological method on cell culture, as well as the state of anti-influenza immunity in serological reactions. The clinical characteristic of the flu was carried out according to the annual reports of the infectious diseases hospital.
Results. An increase in the incidence of influenza in the Krasnodar Territory in the period under review was established. Monitoring of the circulation of the pathogen shows the presence of serotypes A and B in the region of influenza viruses. Among hospitalized adult patients, young people, women, with a moderate course of the disease predominate. The highest incidence and severity of influenza was observed in 2016, when pandemic A(H1N1)pdm09 virus prevailed. There has been an increase in the complicated course of the flu since 2016, despite the diversity of the dominant species of the virus. The leading position among the complications is pneumonia.
Conclusion Epidemiological monitoring is the basis of anti-epidemic and preventive measures. In connection with the marked tendency to an increase in the incidence and an increase in the complicated course of the flu, its rapid diagnosis in the outpatient setting for early etiotropic treatment is necessary.
