In Table 1 only the statistically significant risk factors associated with a higher likelihood to acquire RSV-induced LRTI, severe enough to lead to hospital admission, are reported.
A case-control study was used to evaluate the risk factors associated with higher likelihood to acquire RSV-induced LRTI, severe enough to lead to hospital admission, over four consecutive winter epidemics in Italy (2000 2004).
In the bivariate analysis we considered several risk factors that could be associated with a higher likelihood to acquire RSV-induced LRTI, severe enough to lead to hospital admission.
The aim of the present study was to identify through logistic regression analysis, risk factors associated with higher likelihood to acquire RSV-induced LRTI, in children with symptoms severe enough to lead to hospital admission.

> -wrap-foot> a Likelihood ratio test The area under the ROC curve of the model was 0.712 Evaluating data collected over four consecutive years in Italy, we found that, in addition to the severity of the RSV epidemics in a specific year, a variety of risk factors were associated with a higher likelihood to acquire RSV-induced LRTI, severe enough to lead to hospital admission.
On the one hand, abnormal airway function that is congenitally present or acquired before RSV LRTI occurs could be the cause of both RSV LRTI and subsequent recurrent wheezing.
The epidemic curve (Fig. 1) shows the seasonal distribution of acquired positive RSV results by month.
Other children at risk of acquiring severe RSV disease include those with congenital heart disease, congenital lung malformations, chronic lung disease, and neuromuscular disease.
Contrary to CD4 T cells, high percentages of CXCR3+ CD8 T cells were acquired in RSV-infected children, confirming their preferential differentiation into type-1 phenotype and importance in antiviral immune responses [ 33].
RSV is acquired during a "season".
