“During a health threat such as a coronavirus, people should wear masks in public. Wearing masks gives people some protection. At the same time, many masks hide the lips and half of the face, which makes it harder to understand speech. It is also hard to understand sign language when the person is wearing a mask. Facial expressions are an important part of sign language. It is very important to wear masks to stay safe during a pandemic, but also very important that deaf and hard of hearing people can understand what everyone is saying.
Our guidelines explain the best ways to communicate with deaf and hard of hearing people while following health recommendations. Our guidelines do not explain how much each mask or face shield protects people from any virus.”
