Children and Secondhand Smoke

19-month old visits Grandpa's house; "as soon as we left, he began wheezing. That night he had a high fever and could barely breathe." Taken to the emergency room, he was diagnosed and admitted with pneumonia. What happened? At Grandpa's he was exposed to secondhand smoke. Unusual? Sadly, no. Each year, secondhand smoke causes up to 300,000 respiratory tract infections such as pneumonia in infants and young children.
