Pandemic virus may have interfered with RSV
Writing in Eurosurveillance, French researchers report that respiratory syncytial virus (RSV) circulation in France in late 2009 was reduced and delayed compared with a year earlier, and that this might be explained in part by H1N1 flu. "The influenza pandemic wave of 2009 seems to have partially overcome the RSV epidemic," they write. Viral interference and/or increased hygiene measures in response to H1N1 might have affected RSV activity, they suggest.

Myocarditis reported in young flu patients
Although acute myocarditis as a complication of a viral infection is fairly rare, physicians from a San Diego children's hospital yesterday described four cases that occurred in a 30-day period in children who had pandemic H1N1 infections. They reported their findings in a letter in the Journal of the American College of Cardiology. Of three children who had fulminant myocarditis, one died and two required extracorporeal membrane oxygenation. The fourth had acute perimyocarditis.
