Association of Respiratory Viral Infection and Asthma

The association between lower RTIs, acute exacerbations of asthma, and the initial onset of asthma in infants has been documented in numerous epidemiologic studies.[2,3,4,5,6,7] This association has been noted particularly with occurrences of RSV infections. Whether symptomatic infections in early life induce or identify asthma in genetically susceptible individuals has not yet been documented. The current prevailing view is that infections in early life do not induce atopic asthma. Specifically, RSV infection is not generally viewed as a key event in the induction of asthma.[8]
