Use of Cloth Face Coverings to Help Slow the Spread of COVID-19

How to Wear a Cloth Face Covering
Applying a face mask - step 1

Cloth face coverings should—
  • fit snugly but comfortably against the side of the face
  • be secured with ties or ear loops
  • include multiple layers of fabric
  • allow for breathing without restriction
  • be able to be laundered and machine dried without damage or change to shape
CDC on Homemade Cloth Face Coverings
CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies), especially in areas of significant community-based transmission.
CDC also advises the use of simple cloth face coverings to slow the spread of the virus and help people who may have the virus and do not know it from transmitting it to others. Cloth face coverings fashioned from household items or made at home from common materials at low cost can be used as an additional, voluntary public health measure.
Cloth face coverings should not be placed on young children under age 2, anyone who has trouble breathing, or is unconscious, incapacitated or otherwise unable to remove the mask without assistance.
The cloth face coverings recommended are not surgical masks or N-95 respirators. Those are critical supplies that must continue to be reserved for healthcare workers and other medical first responders, as recommended by current CDC guidance.
Applying a face mask - step 2

Should cloth face coverings be washed or otherwise cleaned regularly? How regularly?
Yes. They should be routinely washed depending on the frequency of use.
How does one safely sterilize/clean a cloth face covering?
A washing machine should suffice in properly washing a face covering.
How does one safely remove a used cloth face covering?
Individuals should be careful not to touch their eyes, nose, and mouth when removing their face covering and wash hands immediately after removing.

Sewing a facemask - materials needed

Materials
  • Two 10”x6” rectangles of cotton fabric
  • Two 6” pieces of elastic (or rubber bands, string, cloth strips, or hair ties)
  • Needle and thread (or bobby pin)
  • Scissors
  • Sewing machine
Tutorial
1. Cut out two 10-by-6-inch rectangles of cotton fabric. Use tightly woven cotton, such as quilting fabric or cotton sheets. T-shirt fabric will work in a pinch. Stack the two rectangles; you will sew the mask as if it was a single piece of fabric.

2. Fold over the long sides ¼ inch and hem. Then fold the double layer of fabric over ½ inch along the short sides and stitch down.

3. Run a 6-inch length of 1/8-inch wide elastic through the wider hem on each side of the mask. These will be the ear loops. Use a large needle or a bobby pin to thread it through. Tie the ends tight.
Don’t have elastic? Use hair ties or elastic head bands. If you only have string, you can make the ties longer and tie the mask behind your head.

4. Gently pull on the elastic so that the knots are tucked inside the hem. Gather the sides of the mask on the elastic and adjust so the mask fits your face. Then securely stitch the elastic in place to keep it from slipping.

CDC releases instructions for making cloth face masks
From CNN’s Nick Valencia and Wes Bruer

The US Centers for Disease Control and Prevention has released instructions and visual tutorials on how to make cloth face coverings from common household materials.

The CDC recently released guidance recommending the use of cloth face coverings "in public settings where other social distancing measures are difficult to maintain, especially in areas of significant community based transmission."

Cloth face coverings, according to the CDC, can be homemade out of pieces of fabric, T-shirts, bandannas and coffee filters to slow down the spread of the virus, especially those that may be asymptomatic and capable of transmitting it to others despite experiencing no symptoms.

The CDC recommended any homemade cloth face coverings include multiple layers of fabric, be secured to the ears, and allow for breathing without restriction. The guidance recommends routinely cleaning coverings in a washing machine and that no child under the age of 2 should wear them.
 
加拿大的卫生部跟进吗?也得鼓励在家做口罩啊。
 
鼓励,终于有人开始干正事了。希望有效吧。
 
胸罩那个最简单最快。然后,就可能是棉破背心了。

看懂这个口罩,我想起上甘岭来。
 
这个挺厚,还漏很多气吧
要是有人在你身边咳嗽,这个应该能防止那些肉眼可见的飞沫直接落入鼻孔
 
加拿大还没决定是否戴口罩,但建议公众捐献自己的医用口罩。
 
跟那些工业防尘的比呢?homedepot 应该能买的到
我买了一盒防尘口罩,还是高价买的。那个小伙子买了好多压在手里。
后来儿子告诉我,好多建筑工人油漆工买不到防尘口罩不能上班。没办法啦,省着用。
艰难时刻每个人都不容易。
