The Evaluation of Impact of Some Epidemiologic Factors on the Bronchiolitis Caused by Respiratory Syncytial Virus (RSV) in Infants and Young Children Under 5 Years Old in Al- Diwaniyah Province
Bronchiolitis Caused by Respiratory Syncytial Virus (RSV)
Abstract
Background:. The biggest viral cause of bronchiolitis and one of the major agents behind respiratory-tract infections globally is the Human Respiratory Syncytial Virus (HRSV). RSV is transmitted through airborne droplets or close contact with contaminated objects
Objective: This purpose of this research for detecting Major risk factors associated with susceptibility and Severity of Bronchiolitis in infants and young children under the age of five is caused by respiratory syncytial virus (RSV). study design to detection antibodies Immunoglobulin M( IgM) for human RSV in serum samples by using specific An enzyme-linked immunosorbent assay (ELISA) kits as adiagnostic test

Statistical analysis was conducted to identify significant risk factors.
Results: This cross sectional study was conducted in Iraq Diwaniyah city. The current study showed that 24 (48.0%) positive samples out of 50 samples were have RSV infection. Risk factors for severity of infection were identified in terms of Age , Sex, exposure to smoking , type of feeding, Prematurity. the frequency distribution of Respiratory Syncytial Virus according to age showed the children less then 1 years male sex, expose to tobacco smoke and artificial feeding they are more susceptible to infected with RSV.
Conclusion: Several risk factors have been associated with susceptibility and Severity of bronchiolitis caused by RSV in infants and young children under 5 years old.
