    A Benefit of Flu: Protection from Asthma? - Science Daily

    In a paper that suggests a new strategy to prevent asthma, scientists at Children's Hospital Boston and their colleagues report that the influenza virus infection in young mice protected the mice as adults against the development of allergic asthma.

    The findings, published online December 13 in the Journal of Clinical Investigation, provide a potential immunological mechanism in support of the "hygiene hypothesis," an idea that attributes the increasing rate of asthma and allergies to the successful reduction of childhood infections with vaccines and antibiotics. The hygiene hypothesis is also supported by epidemiological studies associating certain childhood infections, such as respiratory viral infections or gastrointestinal infection with H. pylori, with a lower risk of developing asthma.

    "Some infections appear to result in important protective effects against asthma," says Dale Umetsu, MD, PhD, of Children's Division of Immunology, a senior author of the paper, and Professor of Pediatrics at Harvard Medical School. "But we certainly don't want to give people dangerous infections to prevent asthma. So if we can understand how infections prevent asthma, we may be able to replicate the good parts and avoid the bad parts of infection and develop new treatments for children to prevent asthma."
