evidence acquisition this article aims at offering clinicians a brief update on the recent epidemiology of respiratory infections in pediatrics. it also underlines the fact that any evidence-based recommendation needs more research in different areas. context respiratory tract infections are the main cause of children’s morbidity and mortality both in the developing and the developed countries....

Background and Aims: The role of BK and JC polyomaviruses (BKV and JCV) in the causation of respiratory disease and the natural route of transmission has not well been established. The aim of study was to determine the prevalence of BK and JC viruses in 280 respiratory samples and evaluate their contribution to respiratory disease. Materials and Methods: PCR was used to screen specimens for BK...

Experts of the Union Pediatricians Russia have developed modern guidelines on management children with acute respiratory viral infection. The term “acute infection” (ARVI) combines following nosological forms: nasopharyngitis, pharyngitis, laryngitis, tracheitis, laryngopharyngitis, upper respiration tract infection (unspecified). issues epidemiology, diagnosis, treatment, and prevention been c...

results among the 158 children evaluated in this study, 49 individuals (31.1%) had rsv infection while nine individuals (5.7%) had hmpv infection. five (55.5%) of the hmpv-infected children were male while four (44.5%) were female and 27 (55.2%) of the rsv-infected patients were females and 22 (44.8%) were males. the rsv infections were detected in mainly < one year old children and hmpv infect...

Viral respiratory tract infections are the most common illnesses affecting children. The reported incidence of upper respiratory infection is 24% for all children less than 5 years of age. Several studies have attempted to standardize upper respiratory infection symptoms in an effort to distinguish patients with upper respiratory tract infections. In general, most clinical studies require the p...

avian infectious bronchitis (ib) is a major cause of economic losses in poultry industry. the ib virus primarily affects respiratory tract, but various strains differ in their tropism for other target organs such as kidney and alimentary tract. the objective of this study was to estimate the pathogenicity of iranian ibv variant (ir-1), which is limited exclusively to iran. specific pathogen fre...

The role of viral respiratory tract infections in acute exacerbations of asthma was studied prospectively in 31 patients with atopic asthma aged 15-56 years. Patients recorded symptom scores for asthma and peak expiratory flow rate daily for 11 months. In addition, they reported for detailed clinical, functional, and virological study every four weeks and as soon as possible after the onset of ...

conclusions although several studies have investigated viral respiratory co-infection, no study has evaluated the rate of respiratory co-infections in adenovirus-positive samples from children younger than 5 years. however, this study has filled this gap, the the number of co-infections were too small to draw any definite conclusions. therefore, large-scale studies using bigger samples are requ...

Influenza is a viral infection of the respiratory tract. Infection is normally confined to the upper respiratory tract but certain viral strains have evolved the ability to infect the lower respiratory tract, including the alveoli, leading to inflammation and a disease pattern of diffuse alveolar damage. Factors leading to this sequence of events are novel influenza strains, or strains that hav...

Background: Human parvovirus B19 was known as one of the possible cause of mild respiratory tract diseases in previous studies. However, there are some reports of acute obstructive respiratory disease and severe pneumonia. The purpose of current study was to assess the prevalence and clinical features of parvovirus B19 in respiratory infection. &nbsp;&nbsp; Methods: This study was conducted on...
