Face Masks are one tool utilized for preventing the spread of disease. They may also be called dental, isolation, laser, medical, procedure, or surgical masks.

The Centers for Disease Control and Prevention is recommending that health care workers treat it like an airborne pathogen - germs that can travel in particles or droplets in the air. That means health care workers interacting with a coronavirus patient should wear a heavy-duty mask called an N95 respirator. These respirators are designed to fit tightly around the nose and mouth, and, when worn correctly, block out at least 95% of small airborne particles, according to the CDC.
