Face shields and mask shields alone are ineffective against COVID-19. Here is why.
We published an earlier version of this story on April 5, 2021. It is worth repeating:
A simple study shows the limits of a plastic face shield. And that they will not protect us from the virus. But they have some benefits.
Plastic shields have limited protection. Instead, you need to wear a face mask. Masks are key to halting the virus.
A study done at the Florida Atlantic University shows that a face shield alone will not protect the person wearing the shield. Also, they will not protect others.
Recently, HMI has found an alarming number of people wearing mask shields. They are plastic that sits over the mouth area but does not make skin contact. Like face masks, they provide limited protection. And they should not be worn.
Face shields and face masks alone do not protect us. But they do provide advantages. Experts point out that a face shield will protect the eyes and discourage touching of the face.
There are several key steps to take to reduce the spread of the virus. But getting fully vaccinated is key.
In some cases, wearing a mask is still key. And this includes those working with vulnerable populations and young children.
Masks Telegraph a Key Health Message
A mask is a health message. Wearing one telegraphs an important health message.
A mask reminds the person wearing it that the virus is serious. It also reminds others of the same message, too. Please set a positive example for others. Wear a mask.
Masks Protect the Person Wearing the Mask
Masks help protect us from the virus. This is key.
Masks Protect Others, too
Masks also protect others if we have the virus. It can be days before symptoms appear. Yet, you could still spread it. Also, some people carry the virus but never experience symptoms themselves.
Thus, face shields and mask shields alone are ineffective against COVID-19. And vaccinations is key.
