Climate change and the end of the respiratory syncytial virus season

The seasons associated with laboratory isolation of respiratory syncytial virus (RSV) ( for 1981-2004) and RSV-related emergency department admissions ( for 1990-2004) ended 3.1 and 2.5 weeks earlier, respectively, per 1 degrees C increase in annual central England temperature (P = .002 and .043, respectively). Climate change may be shortening the RSV season.
