二手烟暴露是一个重要的可预防的疾病和死亡原因。二手烟会导致不吸烟的成年人患肺癌和心脏病，婴儿和幼儿患支气管炎和肺炎等严重疾病，不吸烟妇女的婴儿出生体重不足和婴儿猝死综合症。虽然美国在减少二手烟暴露方面取得了巨大进展，但许多成年人和儿童仍处于危险之中。

Secondhand smoke exposure is an important preventable cause of illness and death. Secondhand smoke causes lung cancer and heart disease in adult nonsmokers, serious illnesses such as bronchitis and pneumonia in infants and young children, and low birth weight and sudden infant death syndrome (SIDS) in infants of nonsmoking women. While the nation has made tremendous progress in reducing secondhand smoke exposure, many adults and children remain at risk.
