The World Health Organisation informs us that touching the face with the hands is one method by which COVID 19 is transmitted: Their advice for preventing infection is: “Avoid touching eyes, nose and mouth. Why? Hands touch many surfaces and can pick up viruses. Once contaminated, hands can transfer the virus to your eyes, nose or mouth. From there, the virus can enter your body and can make you sick.”
It is widely recognised that face touching is habitual and largely subconscious. This device allows users to break the subconscious nature of face touching and take control of it. We can all do our bit to prevent coronavirus.
