Respiratory infection are mainly caused by viral pathogens. During the 2017–2018 epidemic season, Panther Fusion® Respiratory kits (Influenza virus A&B (FluA&B), respiratory syncytial virus (RSV), adenovirus (ADV), metapneumovirus (MPV), rhinovirus (RV), parainfluenzae virus (PIV), were compared to the Respiratory MultiWells System r-gene. Respiratory clinical specimens were tested retrospectively (n = 268) and prospectively (n = 463). Analytical performances were determined (sensitivity –Sep-, specificity –Spe- and κ) considering concordances of ≥2 molecular testing specific to each viral target (discrepant results were verified at the National Reference Centres for Enteroviruses or Respiratory viruses, Lyon, France). After retrospective (and prospective) testing, Sep, Spe, and κ were 100% (97.7%), 100% (99%) and 100% (94%) for FluA: 100% (95.5%), 100% (99.3%) and 100% (94%) for FluB, and 100% (88.5%), 100% (98.7%) and 100% (89%) for RSV; 82.1% (41.7%), 100% (99.5%) and 86% (54%) for ADV; 94.7% (73.7%), 96.1% (98.0%) and 91% (65%) for MPV; 96.1% (94.6%), 90.2% (98.5%) and 86% (91%) for HRV; and 90% (72.7%), 100% (99.3%) and 91% (72%), respectively, for PIV. Analytical performances were above 85% for all viruses except for ADV, MPV and PIV, confirming the analytical performance of the Panther Fusion system, a high throughput system with reduced turn-around-time, when compared to non-automated systems.

The research presents results of the analysis by polymerase chain reaction of clinical material obtained from 170 children hospitalized into an infectious department of the Khabarovsk children’s territorial clinical hospital named after A.K.Piotrovich with a diagnosis of acute viral infection in epidemic season of 2015-2016. The most numerous group consisted of children under 1st year of age – 74 children (43.5%). The overall number of detected respiratory viruses was equal to 179. Most prevalent viruses were human rhinoviruses (25.1%), human adenoviruses (19.6%), and human parainfluenza viruses (16.8%). Among influenza viruses (11.7%) type A(H1N1) pdm09 was predominant. In 92 children (54.1%) the disease was caused by a mono-infection, in 40 cases (23.5%) there was identified mixed-infection. Infections of lower respiratory tract were identified in 100 patients (58.8%), stenosing laryngotracheitis was diagnosed most frequently (20.6%).

Relevance. Vaccines are regarded as an effective means for control of the Covid-19 pandemic spreading and their search, analysis, and comparison of their features are important for elucidating the most safe and effective one. Aim. At the end of 2020 two types of vaccines (viral based vaccines and mRNA vaccines) have been licensed to vaccinate. The aim is to compare their features for objective substantiation of their application. Conclusions. As both vaccine types have high effectiveness in inducing antibodies to SARS-Cov-2 (in more 90% recipients) the utility of each vaccine type in blocking the Covid-19 pandemic spreading is beyond doubt. In both vaccine types eventually S protein is the antigen source, and they have limitations for vaccination. In comparison with the vector vaccines mRNA vaccines may induce serious complications, have the least potential to induce trained immunity and can be included into the recipient’s genome. The low frequency of influenza cases in the current epidemic season serves as an of interference between SARS-Cov-2 and influenza viruses. In epidemic seasons after the Covid-19 pandemic coronaviruses may dominate amongst viruses inducing acute respiratory viruses diseases. It is likely that the decline of the Covid-19 case count (in December-January) in Russia is determined by the heterologous collective immunity formed earlier.

Tract Damage

Long time the main pathogens associated with the development of community-acquired pneumonia were bacteria. However, in recent years in the Russian Federation, like all over the world, the view of the damage of lower respiratory tract changed, including a unique approach to community-acquired pneumonia as a bacterial infection, and respiratory viruses have become seen as a direct cause of lower respiratory tract damage, or as part of a viral-bacterial co-infection. These studies became possible since the widespread introduction of PCR techniques in the clinical setting, identification of respiratory viruses has increased and new microorganisms such, one as human bocavirus have been discovered. Objective: to study the features of respiratory tract damage in acute bocavirus infection in children of different ages. Materials and methods: A retrospective analysis of 97 medical hospital documentation of children with acute bocavirus infection, detected confirmed by PCR in nasopharyngeal aspirate. Results: In this work, it was shown that human bocavirus spread throughout the year with an increase in the incidence of clinically significant forms in the autumnwinter period, including during the period of an increase in the incidence of influenza. HBoV infection requiring hospitals is most significant in the first three years of life. In 74.2% of hospitalized children, bocavirus infection occurs with lower respiratory tract infections in the form of bronchitis — 77.8%, pneumonia — 28.9% and rarely bronchiolitis and is complicated by the development of respiratory failure in 28.9% of cases. Changes in the blood test are non-specific, and the level of C-reactive protein in children with various clinical manifestations of HBoV infection generally does not exceed 50 mg / l. An x-ray of the chest organs does not objectively reflect the existing volume and nature of the inflammatory process in the lungs.
