I'm not confused. The sars cov2 causes flu symptoms because it is a flu. I know because I've had it already and I'm now immune. I was with my friend who had it recently and I never got any symptoms because of my natural immunity.
Living in fear? That's incredibly hypocritical coming from someone who was so scared of a harmless flu that they took an experimental mRNA poison, not once but 3 times. Let that sink in for a second, and rethink your trajectory in life.
