Mathematical modeling of the effectiveness of facemasks in reducing the spread of novel influenza A (H1N1).

On June 11, 2009, the World Health Organization declared the outbreak of novel influenza A (H1N1) a pandemic. With limited supplies of antivirals and vaccines, countries and individuals are looking at other ways to reduce the spread of pandemic (H1N1) 2009, particularly options that are cost effecti...
