好像口罩对健康人群预防流感作用不是那么大,主要还是有流感症状的人应该带口罩,防止细菌传播。今天公司发的一份资料上这样说的,摘录在下面。
Despite much media coverage about masks, there is little evidence that people who are well are protected by wearing a surgical mask. An important consideration when assessing the efficacy of facemasks is that of adherence to correct usage. Disposable masks need to be fitted correctly and changed every time a sneeze or cough occurs, and when removed for eating and drinking. Influenza viruses may pass through or around "paper" masks, and respirators of the N95 or P1/P2 type.
However, for persons who already have symptoms and signs of influenza, the Australian Department of Health and Ageing has recommended that wearing of simple masks may help to stop that person spreading droplet infections when they are in the infective stage of their disease.
