Evaluation of the incidence of identified types of respiratory viruses in a selected population of inhabitants of the kuyavian-pomeranian voivodeship

Abstract

Introduction: Respiratory tract infections are caused by various factors including respiratory viruses, for example influenza virus and respiratory syncytial virus (RSV). Surveillance of influenza and other respiratory viruses is carried out as part of the SENTINEL and NON SENTINEL programs in Poland.<br>Aim of study: Determination of the frequency of selected types of influenza and RSV viruses using real-time reverse transcription polymerase chain reaction method (real-time RT-PCR) in a selected population of inhabitants of the kuyavian-pomeranian voivodeship in the epidemic season 2017/2018, i.e. from 1 October 2017 to 30 April 2018.<br>Material and methods: 201 throat and nasal swabs were tested using real-time RT-PCR method for the detection of the presence of genetic material RNA of influenza virus and RSV. The study population was divided into 7 groups depending on age.<br>Results. Positive samples accounted for 48.26% of the swabs tested. The genetic material RNA of influenza virus was found in 95 (47.26) samples and RSV in 2 (1,00%) samples. Influenza B virus was most frequently isolated. The most prevalence of infections was observed in people under 25 years of age.<br>Conclusions: Surveillance of influenza in the SENTINEL and NON SENTINEL programs constitute an important role in assessing the virological and epidemiological situation prevailing in a given area. The results cover part of the population, hence the data may be underestimated. It is necessary to continue studies and observe the virological and epidemiological situation in the polish population.
