This is because it's harder to spread the infective respiratory droplets more than 6 feet.

这是因为传染性呼吸道飞沫很难传播到2米以外。

And the primary mode of transmission that we really need to focus on is the respiratory droplets.

我们真正需要关注的主要传播模式是飞沫。

That stemmed from how we thought the virus spread — through those large respiratory droplets that I mentioned earlier.

这源于我们所认为的病毒传播途径——通过我之前提到的那些大飞沫。

When someone infected with M. pneumoniae coughs or sneezes, they create small respiratory droplets that contain the bacteria.

当某人感染了肺炎支原体咳嗽或打喷嚏时，他们会产生含有细菌的小呼吸道飞沫。

When the pandemic started, public health experts thought that transmission happened through large respiratory droplets that fell out of the air within 3 to 6 feet.

当新冠疫情开始时，公共卫生专家认为传播是通过3到6英尺内从空气中掉落的大块飞沫进行的。

A simple mask blocked nearly all of the germs, and even though this experiment detected bacteria and not viruses, they both leave our airway in the same respiratory droplets.

一个简单的口罩几乎可以阻挡所有的细菌，虽然这个实验测试的是细菌不是病毒，但是它们都会在相同的呼吸道飞沫中离开我们的呼吸道。
