典型的感染感冒的过程是一个已经感冒了的人在你周围打喷嚏，咳嗽或者同你握手，而表现出感冒的症状还需要几天的时间。
2·And the problem is that when someone sneezes they tend to take a mask off. I think masks give people a false sense of security.
另一个存在的问题是，很多戴口罩的人真打喷嚏的时候还是会先把口罩摘掉，所以我认为口罩给人们的是一种错误的安全感。
3·Whenever someone sneezes or coughs, those nearby try to walk away as fast as they can without being rude.
任何时候，当有人打喷嚏或咳嗽时，周围的人群就会以最快而又尽量不显无礼的速度避而远之。

当人们非常密集地生活在一起，被传染的病人咳嗽或打喷嚏的时候，麻疹、腮腺炎和风疹病毒就很容易传播开来。
5·When an infected person sneezes, coughs or talks, the virus is released into the air and can be spread to other people.
当被感染的人打喷嚏、咳嗽或说话时，病毒被释放出来并向周围的人群扩散。
