@danab- Good morning Dana. I agree that there is much confusion still afloat in the covid world. One promising thing that I read this morning is the possibility of standardized masks. But, Dr. Fauci, in this video, quotes the CDC and says that it might not happen. I disagree with him. I think that in the future we will see very good masks that won't be uncomfortable. I think that as the new administration gains more of a footing there will be more standardized protocols. But remember, Dana, doctors are notorious for disagreeing on major issues.
