The only time I got the flu (about 17 yrs ago at this point), was the year my old workplace was offering the flu vaccine free. My wife and I lost all smell as well. My son brought it home from college. He and my daughter were the first to get sick. They brushed it off like it was a minor cold. Then my wife & I got it. We discussed going to the hospital. Thankfully my wife was a rock there and was determined to not go that route. My friend's brother caught it as well. He convinced his brother to go to the hospital. He described it as a bad cold. They immediately put him on a respirator and pumped him full of drugs. He developed all kinds of clots. They had to amputate a leg. Then as things took a turn for the better and was about to be released, he had a severe brain aneurism and died. It just reinforced all the shit we had been reading about.
