Background: Influenza virus and other respiratory viruses have been identified as an essential cause of acute respiratory infections (ARIs) in children worldwide. However, there are few data on its frequency and clinical presentation in Jordan. Objectives: We aimed to identify the viral etiology of acute respiratory infections and the various clinical presentations in hospitalized children, especially those with influenza viruses compared to other respiratory viruses. Methods: A retrospective study that was conducted at the Jordan university hospital. All the positive nasopharyngeal aspirates that were collected from hospitalized children aged 0-19 years from January 2017 to January 2019 were reviewed. Results: A total of 338 nasopharyngeal aspirates (NPAs) with positive viral serology results were reviewed. Among the patients younger than four years, the RSV virus was the most frequently detected. However, the Influenza B virus was the most commonly seen in patients older than 5 years, H1N1 was more frequent in autumn (29.5%), and RSV was the most frequent virus in winter. Bronchopneumonia was the most frequent diagnosis among all hospitalized patients, followed by bronchiolitis. Out of 338 patients, 50.3 % had tachypnea, 70.7% of patients were admitted to the pediatric floor, while 18.6% presented with a severe illness and required admission to the pediatric intensive care unit (PICU). Infants under the age of one were more likely to have higher co-infection rates with other viruses compared to children over five years that had influenza. Conclusion: Presentations of influenza and other respiratory viruses vary between different age groups, such as sepsis in children younger than one year.

Background and Objectives: Severe acute respiratory infections (SARI) remain an important cause for childhood morbid- ity worldwide. We designed a research with the objective of finding the frequency of respiratory viruses, particularly WU and KI polyomaviruses (WUPyV & KIPyV), human coronaviruses (HCoVs), human respiratory syncytial virus (HRSV) and human parechovirus (HPeV) in hospitalized children who were influenza negative. Materials and Methods: Throat swabs were collected from children younger than 5 years who have been hospitalized for SARI and screened for WUPyV, KIPyV, HCoVs, HRSV and HPeV using Real time PCR. Results: A viral pathogen was identified in 23 (11.16%) of 206 hospitalized children with SARI. The rate of virus detection was considerably greater in infants <12 months (78.2%) than in older children (21.8%). The most frequently detected vi- ruses were HCoVs with 7.76% of positive cases followed by KIPyV (2%) and WUPyV (1.5%). No HPeV and HRSV were detected in this study. Conclusion: This research shown respiratory viruses as causes of childhood acute respiratory infections, while as most of mentioned viruses usually causes mild respiratory diseases, their frequency might be higher in outpatient children. Mean- while as HRSV is really sensitive to inactivation due to environmental situations and its genome maybe degraded, then for future studies, we need to use fresh samples for HRSV detection. These findings addressed a need for more studies on viral respiratory tract infections to help public health.

Abstract A cross-sectional viral surveillance study of hospitalized children less than 2 years of old in Amman, Jordan, noted that respiratory syncytial virus and human metapneumovirus, but not human rhinovirus, were associated with higher odds of acute wheezing. Future longitudinal studies are needed to evaluate the association between early childhood viral acute respiratory infections and recurrent wheezing later in childhood.

The aim: to study the etiological structure of acute respiratory infections in children aged 3 to 12 hospitalized in the early stages of the disease in the department of respiratory infections of the children’s hospital, and to reveal the features of their clinical course and the timing of DNA / RNA elimination of respiratory viruses from nasal secretions, depending on the method of therapy. Materials and methods: 100 children with acute respiratory infections aged 3 to 12 years were monitored. The nasal secrets on the DNA / RNA of respiratory viruses were studied by PCR. Depending on the method of therapy, patients were divided into 2 groups: patients of group 1 (comparison) received basic treatment (without the use of antiviral drugs), in patients of the 2nd group (main), along with basal therapy, the drug was used umifenovir in a 5-day course at the ageappropriate dosage. Results: In the etiologic structure of ARVI in children from 3 to 12 years, the leading place was taken by rhinovirus, influenza and metapneumovirus infections (isolated – 18%, 19% and 20% respectively, in the form of a mixed infection – 11%). The main syndromic diagnosis at the height of the disease was rhinopharyngitis. Complications were observed in 42% of cases, as often as possible with flu – 53% of cases. Features of metapneumovirus infection in children of this age group were: predominance of non-severe forms of the disease in the form of acute fever with symptoms of rhinopharyngitis, as well as a small incidence of lower respiratory tract infections. The use of the drug umiphenovir in children with acute respiratory viral infections of various etiologies contributed to significantly faster elimination of viral DNA / RNA from the nasal secretion, which was accompanied by a ecrease in the duration of the main clinical and hematological symptoms of the disease, a decrease in the incidence of complications, and reduced the duration of stay in hospital. Conclusion: application of modern molecular genetic methods of diagnostics made it possible to identify the leading role of influenza, metapneumovirus and rhinovirus infections in the etiology of acute respiratory viral infection in patients aged 3 to 12 years, and to determine a number of clinical features characteristic of this age group. The results of the study testify to the effectiveness of umiphenovir in the treatment of children with acute respiratory viral infections of various etiologies and allow us to recommend this drug as an effective and safe etiotropic agent.

Background. The current study aims to describe the demographical and clinical characteristics of elderly nursing home (NH) residents with acute respiratory infections (ARIs) during four winter seasons (2013/2014–2016/2017), as well as the microbiological etiology of these infections. Methods. Seventeen NHs with at least one ARI resident in Corsica, France, were included. An ARI resident was defined as a resident developing a sudden onset of any constitutional symptoms in addition to any respiratory signs. Nasopharyngeal swabs from ARI residents were screened for the presence of 21 respiratory agents, including seasonal influenza viruses. Results. Of the 107 ARI residents enrolled from NHs, 61 (57%) were positive for at least one of the 21 respiratory pathogens. Forty-one (38.3%) of the 107 ARI residents had influenza: 38 (92%) were positive for influenza A (100% A(H3N2)) and three (8%) for influenza B/Victoria. Axillary fever (≥38°C) was significantly more common among patients infected with influenza A(H3N2). Conclusion. The circulation of seasonal respiratory viruses other than influenza A(H3N2) seems to be sporadic among elderly NH residents. Investigating the circulation of respiratory viruses in nonwinter seasons seems to be important in order to understand better the dynamic of their year-round circulation in NHs.
