口罩的使用与低依从性相关，但依从性口罩使用者可显著预防季节性疾病。许多国家正在储备口罩，作为流感大流行期间控制病毒传播的非药物干预措施。我们进行了一项前瞻性随机分组试验，比较外科口罩、未经适合性测试的P2口罩和不戴口罩在家庭中预防流感样疾病（ILI）的效果。自我报告面罩使用依从性。在2006年和2007年冬季，招募了来自143个家庭的286名接触过临床呼吸道疾病儿童的成年人。我们发现，坚持使用口罩显著降低了ILI相关感染的风险，但<50%的参与者大部分时间都戴口罩。我们的结论是，家庭使用口罩与低依从性有关，对控制季节性呼吸道疾病无效。然而，在严重的大流行期间，口罩的使用可能会更多，家庭中的大流行传播可能会减少。许多国家正在储备口罩，作为非药物干预措施，以减少流感大流行期间的病毒传播。我们进行了一项前瞻性随机分组试验，比较外科口罩、未经适合性测试的P2口罩和不戴口罩在家庭中预防流感样疾病（ILI）的效果。在2006年和2007年冬季，招募了来自143个家庭的286名接触过临床呼吸道疾病儿童的成年人。意向治疗分析显示，与对照组相比，口罩使用组的ILI相对风险无显著差异;然而，口罩使用组中<50%的人报告大部分时间戴口罩。坚持使用口罩与ILI相关感染的风险显著降低相关。我们的结论是，家庭使用口罩与低依从性相关，在控制季节性ILI方面无效。如果更严格地遵守，口罩的使用可能会减少严重流感大流行期间的传播。
Mask use is associated with low adherence, but adherent mask users are significantly protected against seasonal disease. Many countries are stockpiling face masks for use as a nonpharmaceutical intervention to control virus transmission during an influenza pandemic. We conducted a prospective cluster-randomized trial comparing surgical masks, non–fit-tested P2 masks, and no masks in prevention of influenza-like illness (ILI) in households. Mask use adherence was self-reported. During the 2006 and 2007 winter seasons, 286 exposed adults from 143 households who had been exposed to a child with clinical respiratory illness were recruited. We found that adherence to mask use significantly reduced the risk for ILI-associated infection, but <50% of participants wore masks most of the time. We concluded that household use of face masks is associated with low adherence and is ineffective for controlling seasonal respiratory disease. However, during a severe pandemic when use of face masks might be greater, pandemic transmission in households could be reduced.

During the 2006 and 2007 winter seasons, 286 exposed adults from 143 households who had been exposed to a child with clinical respiratory illness were recruited. Intent-to-treat analysis showed no significant difference in the relative risk of ILI in the mask use groups compared with the control group; however, <50% of those in the mask use groups reported wearing masks most of the time. Adherence to mask use was associated with a significantly reduced risk of ILI-associated infection. We concluded that household use of masks is associated with low adherence and is ineffective in controlling seasonal ILI. If adherence were greater, mask use might reduce transmission during a severe influenza pandemic.
