Here is an update on my Covid situation. I am on my 5th and last day of antiviral treatment. My blood oxygen is great, my breathing much easier and my "congested" cough 95% improved. I tested positive (PCR test) for Covid 4 months after my third Pfizer dose and 30 days after my VAT surgery. Symptoms after surgery just changed into symptoms from Covid. Apparently, surgery weakens immune system (and I was under for 3 hours). What is also of note is that I had no contact with family/friends, and I always wore an N95 mask when leaving home, only curbside pickup of groceries/takeout, never entered any building but my own, never lingered in common areas and only occasionally passed someone on the stairs. I use a Merv13 filter with my independent air/heating unit. Therefore, I caught Covid through groceries/takeout food packaging or aerosols in my building. I will start again spraying disinfectant on all packaging. I am looking for a spacesuit.
