Before 2020, it was typical for masks to be used in various forms- such as preventing the intake of toxins like pollution and also used in the medical field to perform surgical procedures, as well as to prevent spreading a cold or a flu to someone else while out in public. In 1897, a head of a surgical department at a university in Poland, Johann Mikulicz began wearing face masks when experimenting and discovering with partner Carl Flugge, that bodily fluids can contribute to the transferring of bacteria while performing procedures on patients. This eventually lead to other surgeons wearing masks as well.

 

Now in 2020, masks are being used the most since they have been invented-used by all of Earth due to a recent virus named Covid-19 now turned pandemic. Today there are many forms of masks such as reusable ones and cloth ones. Wearing a mask helps prevent the spread of this deadly virus.​
