There are many commercial and homemade DIY shields that protect from the spray from an infected person, as well as will act as a barrier to touching your face.
Epidemiologist's reasons why he prefers shields and some shield designs.
See also instructions below for making a homemade shield from items found in most kitchens that can be washed and sterilized for multiple uses and do not require breathing through a suffocating cloth mask.
This shield stops your hands touching your face including your chin, enabling you to remove it without your hands contacting your head.
Shields must be removed carefully to prevent chin and head touching.
Wearing gloves is of doubftful protection since the virus does not penetrate the skin, unless maybe through an open wound. For gloves to be effective they must be removed after touching any possibly contaminated object.
Anything that helps keep your hands off your face must be of benefit, and that is the best reason to wear a full face shield, especially one that stops your hands touching your face, especially when removing it. A full-face shield that has side pieces that prevent your hands also touching your hair and head would be the best.
A DIY mask, while not as effective as an N95 mask, still offers some protection from respiratory droplets from someone coughing or sneezing close to you.
Fabric that is 100% cotton is comparable to surgical masks.
If you can't make your mask, the New York City Department suggests covering your mouth and nose with a scarf or bandanna.
There is no conclusive evidence whether the tiny drops generated from breathing and even coughing containing coronavirus remain suspended for any time.
See why a face mask is both of use as protection against inhaling the virus and preventing spreading. See https://endco19.com/preventions.html for a detailed discussion on aerosols and droplet spreading.
If the drops do not remain suspended for much time, as claimed by the World Health Organisation - WHO - a mask will help stop the normal wearer from spreading, but only a shield stops the wearer touching contaminated surfaces and then touching their face.
Medical personal in close contact with CO-19 patients must wear at least the N95 mask, plus a medically approved face shield.
You can make this shield/mask quickly at home from cleaned used plastic food tray parts, glue and a few small pieces of Velcro.
The main idea of this shield is to prevent your hands touching anywhere on your head, including the sides and your chin. However, it would give good protection for both wearer and surrounding parties against sneezing, coughing and hypersalivation or spitting when talking.
Should there be any scientific testing to determine it as a protection against various germs, it will be shown here.
