Some people are going to fairly great lengths to avoid infection with H1N1 influenza. But a review of scientific evidence published Tuesday shows the best way to curb respiratory illnesses is to keep little hands clean. Very little hands. And very clean.

Frequent hand washing; using gloves, gowns and masks with filtration; and isolating sick people were all found to be effective. But children's hygiene had the biggest effect.
