The Bird Mask
Today, doctors know a lot about how to stop germs (病菌) from spreading. They suggest people cover their mouths when they cough. Washing your hands often also helps.
However, people haven’t always known about germs. For many years, even doctors didn’t really understand how illnesses spread.
In 1619, the French doctor, Charles de Lorme, invented a special uniform. He hoped it could protect doctors who were treating plague (瘟疫) patients. The uniform had a long coat, gloves, boots (靴子) and a hat.
The doctors also carried sticks so they wouldn’t have to touch the patients. The most special part of the uniform was the mask (面具).
At that time, doctors believed the plague was spread by bad air. Any air that had a bad smell was dangerous.
Did it work? Well, not really. Certainly the germs sometimes traveled through the air, and the flowers weren’t able to stop them.
Some forms of plague only spread through certain animals such as mice. The doctors’ uniform helped to protect them from this danger. However, largely the coat, gloves, boots and hat did the job, not the bird mask.
