There is much talk these days with COVID-19 about the wearing of masks to cover your nose and mouth when out in public and at the workplace. Some states have mandated the wearing of such masks by employees in retail, construction and manufacturing industries who typically have not utilized such personal protective equipment (PPE). So what's the story and why should you wear a mask?

One diagram that has famously made it around through social media indicates that if everyone wore a mask it would effectively reduce the transmission rate to just 1.5%. That's a great thing but it fails to identify what type of mask nor reference the study for the basis of the data. Searching the archives of studies shows little data on the effectiveness of dust masks or fabric face coverings in the reduction of transmission of diseases.

Masks come in all sorts of varieties from the N95 filter masks used by health professionals, homemade fabric masks, all the way to a bandana around your nose and mouth. If you look at the studies and the various government sites, the evidence shows that masks such as the professionally manufactured N95 mask clearly can help prevent the spread of diseases such as COVID-19. However, there is really no data on the effectiveness of homemade or many other types of masks mainly because there are such huge variables in the material and design. Different types of materials have different types of filtering capabilities and design along with fit of any one particular mask on an individual can certainly change the odds.

So why wear a mask when you're at work or even out in public? Let's look at four solid reasons:

When wearing a mask it is important to keep several things in mind:
