More kids, more viruses at home
A study conducted during the 2009 H1N1 influenza pandemic found that families with multiple children had a respiratory viral infection in the household for more than half of the year between August 2009 and August 2010.
Families with two to four children had at least one respiratory viral infection in the household for slightly more than half the year. Families with six children had at least one viral infection in the household for 87% of the year.
