Looking for benefits of climate change on human health?: first signs of reductions in a shorter season for the RSV virus in the UK
Analysis of hospital admissions (1990-2004) and hospital lab reports (1981-2004) across England and Wales suggest that the season for the RSV virus (which is a prime cause of bronchiolitis and pneumonia amongst small children, but can affect all age groups) has been ending about 2 to 3 weeks earlier for each degree of rise in regional annual air temperatures. In contrast, rising temperatures have not affected the onset of the season.
