Children living in households put each family member at greater risk for viral infection, according to results from the Utah Better Identification of Germs-Longitudinal Viral Epidemiology study — or BIG-LoVE. Larger families have viral infections for up to 87% of the year, although only about half of those infections cause illness, researchers said.
Carrie L. Byington, MD, of the University of Utah, and colleagues conducted the prospective BIG-LoVE study from August 2009 to August 2010 — a period that included the second wave of the 2009 influenza A(H1N1) pandemic. The study included 26 households with 108 individuals. Families ranged from single-individual households to families of three to eight people.
