Title: Association of specific viral infections with childhood asthma exacerbations Document date: 2018_9_27
ID: rqmjras4_27
Snippet: The rate of viral detection in asthma acute exacerbations has been greatly varied in previous studies. While viruses have been detected in up to 85% of asthma exacerbations in different studies [7, 16] , in a study performed by Liao et al. [17] later, the rate of positive viral detection using PCR in acute asthma exacerbation was 34.2%. In this study, we could identify a potential viral causative agent as the reason of acute asthma exacerbation i.....
Document: The rate of viral detection in asthma acute exacerbations has been greatly varied in previous studies. While viruses have been detected in up to 85% of asthma exacerbations in different studies [7, 16] , in a study performed by Liao et al. [17] later, the rate of positive viral detection using PCR in acute asthma exacerbation was 34.2%. In this study, we could identify a potential viral causative agent as the reason of acute asthma exacerbation in 23 (38%) of our patients. This rate is in agreement with the one reported by Liao et al. [17] . This wide variation among asthmatic individuals in different studies may denote the influence of additional factors, such as the possible effect of atmospheric pollution in association with viral infections in inducing asthma attack.
