Mouth shield is a transparent plastic made to cover the mouth part of a person\u2019s face. Like a face shield, it serves as a barrier of Covid-19 transmission, but it only covers the lower part of the face. It is also similar to a chef wearing a mouth shield to prevent the transfer of germs and diseases to food; its purpose is to avoid saliva transmission among people. <\/p>\n\n\n\n
The CBC News network entertained questions from citizens, and asked experts from concerned fields regarding their opinion on these matters during The National, and on CBC News Network. It helps people find answers to their Covid-19 questions. <\/p>\n\n\n\n
One of the questions is, \u201dcan mouth shields replace cloth masks?\u201d People may be seeking for cheaper alternatives as the crisis continuously reduces personal income. More than a monetary concern, this alternative is primarily an issue of effectiveness.<\/p>\n\n\n\n
Experts firmly responded no.<\/p>\n\n\n\n
\u201cI don’t think they’re a really good alternative at all… These are developed for the food-service industry, and they’re not studied or designed for this purpose at all.\u201d <\/p>Dr. Susy Hota, medical director for infection prevention and control at the University Health Network in Toronto<\/cite><\/blockquote>\n\n\n\n
Based on ROC\u2019s report cited in a blog, \u201c63 percent of workers reported cooking or serving food while sick at some point.\u201d Considering this, germs and diseases that come from a sick cook\u2019s mouth transfer to the food. Mouth shields serve the purpose of blocking this transmission.<\/p>\n\n\n\n
With the blocking of disease transmission to food, people may consider mouth shields to be effective in preventing Covid-19 spread among people. For public health officials, the purpose of wearing these non-medical masks is \u201cto protect others from the droplets spewing from your mouth and nose.\u201d<\/p>\n\n\n\n
There is existing evidence that proves non-medicals masks offer protection for the wearers. In contrast, there \u201clots of opportunities for droplets to get in,\u201d according to Hota, because it only covers the mouth part. <\/p>\n\n\n\n
Mouth shields are the same as face shields. Both have questionable effectiveness compared to face masks. Colin Furness, an infection control epidemiologist and assistant professor at the University of Toronto, said, \u201cfull face shields have the same problem.\u201d<\/p>\n\n\n\n
A study about Covid-19 transmission conducted in Switzerland found out that \u201cnone of the people wearing masks tested positive for the virus. Several of the people wearing only face shields, however, did test positive.\u201d<\/p>\n\n\n\n
In conclusion, mouth shields or face shields are useful supplements to face masks, but should not be used as an alternative.<\/p>\n","protected":false},"excerpt":{"rendered":"
