    Acute respiratory viral infections remain the most common diseases in the world, accounting for about 90% of all infectious diseases. The possibilities of etiological decoding of ARVI using modern examination methods made it possible to establish an increase in the proportion of rhinovirus infection in the structure of ARVI.The aim of the study in this regard was to study the features of the clinical course of rhinovirus infection in children of different ages in modern conditions. The study included 50 patients with rhinovirus infection of children, among whom 1 2 children (24%) were under 1 year old; 34 children (68%) β€” 1β€”3 years old, 4 children (8%) β€” 3β€”7 years old. To confirm rhinovirus infection, a study of mucus from the nasopharynx by PCR was carried out.A thorough analysis of the symptom complex of the infection showed that in 1 3 (26%) patients the infectious process was limited to lesions of the upper respiratory tract, in 14 (28%) there were symptoms of acute stenosinglaryngotracheitis, in 1 1 (22%) children developed pneumonia, in 1 2 (24%) β€” bronchitis, with obstructive syndrome in 1 0 (83.3%) patients in this group.ΠžΡΡ‚Ρ€Ρ‹Π΅ рСспираторныС вирусныС ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΈ ΠΎΡΡ‚Π°ΡŽΡ‚ΡΡ Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ распространСнными заболСваниями Π² ΠΌΠΈΡ€Π΅, составляя ΠΎΠΊΠΎΠ»ΠΎ 90% всСй ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΎΠ½Π½ΠΎΠΉ ΠΏΠ°Ρ‚ΠΎΠ»ΠΎΠ³ΠΈΠΈ.

    Objective. To identify the drift variability of influenza viruses during the period of epidemic rise in the incidence of acute respiratory viral infections in the period 2018-2019. The biological and molecular-genetic properties of epidemic strains isolated in certain territories of the Russian Federation were studied and compared with data from the countries of the Northern Hemisphere. Materials and methods. A range of laboratory diagnostic methods has been applied, including immune fluorescence, RT-PCR, sequencing, methods for determining sensitivity to influenza drugs and receptor specificity. Results and discussion. The proportion of influenza viruses was as follows: A (H1N1) pdm09 - 53 %, A (H3N2) - 46 %, B - about 1 %. Cases of severe acute respiratory infections have most often been associated with influenza A(H1N1) pdm09 virus. According to antigenic properties, isolated strains corresponded to the properties of vaccine viruses (A/Michigan/45/2015 - by 99.6 % and A/Singapore INFIMH-16-0019/2016 - by 86 %). The heterogeneity of influenza A virus strains population was revealed as regards individual mutations in hemaglutinin. The influenza B virus population was equally represented by both evolutionary lines (B/Victoria and B/Yamagata-like). Receptor specificity was favorable for the course and outcome of the disease. Among 70 studied epidemic strains, no strains resistant to anti-neuraminidase drugs, oseltamivir and zanamivir, were detected. The article presents WHO recommendations on the composition of influenza vaccines for the countries of the Northern Hemisphere for 2019-2020, provides data on cases of human infection with avian influenza viruses A(H5N1), A(H5N6), A(H7N9) and A(H9N2)

    The aim of this study was to monitor in-hospital influenza virus infection during 2015 – 2016 epidemic flu season. Methods. Influenza virus was searched in patients hospitalized to a clinical infectious diseases hospital with acute respiratory viral infection during 2015 – 2016 influenza seasonal growth period using real-time RT-PCR method. Influenza virus was isolated from nasal swabs and autopsy material using canine kidney cell line. Other laboratory methods used included complete blood count, blood chemistry, blood gas analysis, urinalysis, and chest X-ray examination. Results. We examined 1,491 patients (375 adults, 546 children, 570 pregnant women with early gestational age). The proportion of hospitalized patients with confirmed A / H1N1pdm09 influenza in January – February, 2016, was 91.3%. A / H3N2 influenza virus was diagnosed in 5.7%, influenza B virus was isolated in 1.2% of patients. Totally, influenza virus was detected in 35.2% of samples, of which 30.1% of samples were obtained from adults, 33.7% of samples were obtained from children, and 39.8% of samples were obtained from pregnant women. The prevalent patient’s age was 15 to 60 years (76.1%) in adults and 3 to 6 years in children. Moderate course of influenza with a high rate of hospital admission was seen more often and was similar to that of 2009 – 2010 epidemic season. Proportion of patients with flu complicated by pneumonia was higher than that in 2014 – 2015 epidemic season. Bilateral lung injury was diagnosed in 48.4% of patients. High mortality in ICU (46.4%) was due to delayed start of antiviral treatment and late admission to a hospital. Conclusion. In 2015 – 2016 epidemic flu season, higher morbidity, complications and poor outcomes were related to predominant infection of A – H1N1pdm09 influenza virus. Risk factors of complications and death were delayed care seeking, lack of modern antiviral medications and comorbidity.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ.

    The World Health Organization (WHO) searches influenza virus circulation in community and in natural biocenosis, studies virus strains and their properties, develops diagnostic methods and preventive measures since 1940th worldwide because of epidemic actuality and high pandemic potential of the influenza virus. The Federal Influenza Center (including Federal Research Institute of Influenza, Saint-Petersburg, and the Center of Virus Ecology, D.I.Ivanovskiy Virology Institute, Honorary Academician N.F.GamaleyaFederal Research Center of Epidemiology and Microbiology, Federal Research Center for Epidemiology and Microbiology, Moscow) performs similar work in Russia in close cooperation with WHO within the framework of the International Programme of Influenza Monitoring. A(H1N1)pdm09 influenza virus dominated in the Northern Hemisphere in the 2015 – 2016 epidemic season. Morbidity growth was noted from the end of January, 2016, to the beginning of March, 2016. The peak morbidity at the 5th week of the year exceeded the epidemic threshold (132 cases per 10,000 of population) and morbidity in the 2014 – 2015 season significantly and approached to the peak morbidity of the 2009 – 2010 epidemic season. The epidemic growth in Russian Federation was provided by three influenza viruses: A(H1N1)pdm09, Π’ and A (H3N2). A(H1N1)pdm09 virus caused 18% of all acute respiratory diseases and accounted for 84% of circulating influenza viruses.Flu was diagnosed in patients of different age with maximal frequency in 3- to 6-year old children. Peak admission number was registered at 5 and 6 weeks (3,538 and 4,109 cases, respectively); this number exceeded the similar parameter of the 2009 – 2010 season. Patients of 15 to 64 years old were admitted more often including those with acute respiratory infection. Two hundred and thirty nine deaths were registered to the 5th of April, 2016, according to data from the Federal Influenza Center and the Center of Virus Ecology. The diagnosis of A(H1N1)pdm09 flu was confirmed in 97.9% of deaths. Molecular analysis of isolated strains of A(H1N1)pdm09 influenza virus revealed amino acid substitutions in receptor binding site and SA site of hemagglutinin and in genes coding intrinsic proteins PA, NP, M1, and NS1. Influenza virus strains resistive to anti-neuraminidase drugs were encountered in #< 1% in the Northern Hemisphere countries. No strains studied were sensitive to adamantine derivates.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ. Π‘ 1947 Π³.

    Influenza Epidemiology And Influenza Vaccine Effectiveness During The 2015-2016 Season: Results From The Global Influenza Hospital Surveillance Network

    No full text
    BackgroundThe Global Influenza Hospital Surveillance Network is an international platform whose primary objective is to study severe cases of influenza requiring hospitalization.MethodsDuring the 2015-2016 influenza season, 11 sites in the Global Influenza Hospital Surveillance Network in nine countries (Russian Federation, Czech Republic, Turkey, France, China, Spain, Mexico, India, and Brazil) participated in a prospective, active-surveillance, hospital-based epidemiological study. Influenza infection was confirmed by reverse transcription-polymerase chain reaction. Influenza vaccine effectiveness (IVE) against laboratory-confirmed influenza was estimated using a test-negative approach.Results9882 patients with laboratory results were included of which 2415 (24.4%) were positive for influenza, including 1415 (14.3%) for A(H1N1)pdm09, 235 (2.4%) for A(H3N2), 180 (1.8%) for A not subtyped, 45 (0.5%) for B/Yamagata-lineage, 532 (5.4%) for B/Victoria-lineage, and 33 (0.3%) for B not subtyped. Of included admissions, 39% were<5years of age and 67% had no underlying conditions. The odds of being admitted with influenza were higher among pregnant than non-pregnant women (odds ratio, 2.82 [95% confidence interval (CI), 1.90 to 4.19]). Adjusted IVE against influenza-related hospitalization was 16.3% (95% CI, 0.4 to 29.7). Among patients targeted for influenza vaccination, adjusted IVE against hospital admission with influenza was 16.2% (95% CI, -3.6 to 32.2) overall, 23.0% (95% CI, -3.3 to 42.6) against A(H1N1)pdm09, and-25.6% (95% CI, -86.3 to 15.4) against B/Victoria lineage.ConclusionsThe 2015-2016 influenza season was dominated by A(H1N1)pdm09 and B/Victoria-lineage. Hospitalization with influenza often occurred in healthy and young individuals, and pregnant women were at increased risk of influenza-related hospitalization. Influenza vaccines provided low to moderate protection against hospitalization with influenza and no protection against the predominant circulating B lineage, highlighting the need for more effective and broader influenza vaccines.Wo

    Influenza Epidemiology And Influenza Vaccine Effectiveness During The 2016-2017 Season In The Global Influenza Hospital Surveillance Network (Gihsn)

    BackgroundThe Global Influenza Hospital Surveillance Network (GIHSN) aims to determine the burden of severe influenza disease and Influenza Vaccine Effectiveness (IVE). This is a prospective, active surveillance and hospital-based epidemiological study to collect epidemiological data in the GIHSN. In the 2016-2017 influenza season, 15 sites in 14 countries participated in the GIHSN, although the analyses could not be performed in 2 sites. A common core protocol was used in order to make results comparable. Here we present the results of the GIHSN 2016-2017 influenza season.MethodsA RT-PCR test was performed to all patients that accomplished the requirements detailed on a common core protocol. Patients admitted were included in the study after signing the informed consent, if they were residents, not institutionalised, not discharged in the previous 30days from other hospitalisation with symptoms onset within the 7days prior to admission. Patients 5years old or more must also complied the Influenza-Like Illness definition. A test negative-design was implemented to perform IVE analysis. IVE was estimated using a logistic regression model, with the formula IVE=(1-aOR)x100, where aOR is the adjusted Odds Ratio comparing cases and controls.ResultsAmong 21,967 screened patients, 10,140 (46.16%) were included, as they accomplished the inclusion criteria, and tested, and therefore 11,827 (53.84%) patients were excluded. Around 60% of all patients included with laboratory results were recruited at 3 sites. The predominant strain was A(H3N2), detected in 63.6% of the cases (1840 patients), followed by B/Victoria, in 21.3% of the cases (618 patients). There were 2895 influenza positive patients (28.6% of the included patients). A(H1N1)pdm09 strain was mainly found in Mexico. IVE could only be performed in 6 sites separately. Overall IVE was 27.24 (95% CI 15.62-37.27. Vaccination seemed to confer better protection against influenza B and in people 2-4years, or 85years old or older. The aOR for hospitalized and testing positive for influenza was 3.02 (95% CI 1.59-5.76) comparing pregnant with non-pregnant women.ConclusionsVaccination prevented around 1 in 4 hospitalisations with influenza. Sparse numbers didn't allow estimating IVE in all sites separately. Pregnancy was found a risk factor for influenza, having 3 times more risk of being admitted with influenza for pregnant women.Wo
