Is wearing reusable clothing mask outside safe in covid?

Depends: If you make an effort to sanitize these on a regular basis (soap/water warm water) or bake in an oven @130 F for 30 min you have essentially started over with a new mask. Masks used along with social distancing/sanitizing hands & other such measures are all fractionally helpful in providing protection. If you just hang it up & reuse it constantly in public you to little to protect you or others.

COVID 19 concerns: Cloth masks should be cleaned regularly. This is safe in most environments. However, surgical masks (or respirators) should be worn if one is coming into contact with patients in a medical setting.

Agree with Dr. F: Wearing mask, practicing social distance and frequent hand hygiene. Take the Covid vaccine at the first opportunity. Wish you good health!
