objectives we assessed the prevalence of three common viruses including; respiratory syncytial virus (rsv), human rhinovirus (hrv), and human metapneumovirus (hmpv), in children with acute wheezing. patients and methods ninety six wheezy children, 48 males (50%) and 48 females (50%)under the age of 5 years, were enrolled in the study. all patients visited as outpatients or inpatients when refer...

Influenza virus and respiratory syncytial virus infection of viral respiratory disease has become a major killer of mankind, but there is no effect of vaccines and therapeuticmdrugs. Chinese herbs can inhibit the proliferation and strengthen the human immune virus, and so on to play a very good antiviral activity. Singleflavor compound in accordance with two different drugs and the object of st...

Seventy-eight unselected children under the age of 2 years suffering from acute respiratory infections were investigated by the fluorescent antibody technique and a comparison was made with conventional isolation and serological methods. Sixty-nine per cent. of children with bronchiolitis were diagnosed as suffering from respiratory syncytial virus infection on the day of admission by examinati...

BACKGROUND Although information about the incidence of viral respiratory illnesses and their associated cost can help health officials explore the value of interventions, data are limited from middle-income countries. METHODS During 2008-2010, we conducted a prospective cohort study and followed ~1,800 Argentinian children aged ≤5 years to identify those children who were hospitalized or who ...

Background and Aims: Respiratory syncytial virus (RSV) infection is common in infants and young children. In infants younger than one year old it may cause bronchiolitis and pneumonia which requires hospitalization. Accurate and rapid diagnosis of the disease will help proper treatment of the disease and prevents further complications. Methods: Specimen taken from respiratory tract of sick chil...

OBJECTIVE to analyze the circulation of respiratory viruses in people living in the metropolitan area of Belo Horizonte, Brazil, and hospitalized in Belo Horizonte from 2011 to 2013. METHODS this is a descriptive study of 5,158 patients with Severe Acute Respiratory Syndrome; a comparison was made between the characteristics of confirmed cases and those of discarded cases or cases without swa...

Hospitalized infants (4,618) were studied for lower respiratory infections from 1989 through 2000 by routine immunofluorescence assay and viral isolation. The hospitalization rate for respiratory syncytial virus (RSV) averaged 2% per year. The fatality rate was 0.1%. Monthly RSV detection varied from 14 to 88%, and epidemics lasted 3.5 to 6 months. From 1994 high-early versus low-late epidemic ...
