An outbreak of influenza-like disease caused illness among 48 per cent of 173 female military recruits, 35 per cent of whom smoked cigarettes. The risk of influenza-like illness was greater in smokers (60.0 per cent) than in nonsmokers (41.6 per cent), with a risk ratio of 1.44 (95 per cent CL 1.03-2.01). Among those ill, a significantly greater proportion of smokers visited the clinic than nonsmokers. This could have been due to more severe illness among smokers, or to a greater tendency to visit the physician. The proportion of influenza-like disease attributable to smoking in this population was 13 per cent.
在173名女性新兵中，48%的人感染了类似流感的疾病，其中35%吸烟。吸烟者患类似流感疾病的风险（60.0%）高于不吸烟者（41.6%），风险比为1.44（95%可信区间1.03 - 2.01）。在患病者中，吸烟者去诊所就诊的比例明显高于不吸烟者。这可能是因为吸烟者病情更严重，或者是因为他们看医生的倾向更强。该人群中因吸烟导致的类似流感疾病比例为13%。
