Yes! I totally got this part, working in healthcare among Covid!
When you put a face mask on make sure you form the nose piece so that nothing is getting in, and make sure it fits you all around, and is not to big or small, because the virus can get in…. Do not touch your face! Wash your hands before you remove it, so important! Remove mask back to front.
Thank God I have a N95 mask for grocery shopping, and with possible Covid patients who have pending Covid tests. I don’t believe that cloth masks are not efficient, if you put a filter in your cloth mask and it fits your face properly you are getting protection!
