Not at all. We have the data. It's called summer. Also, I probably have a weaker immune system than most, and have several risk factors.
We have simply not seen the increases and flare-ups we would expect if what you're asserting is true. What worries me is October-November. This is for Toronto, Canada.

Get outside and take care of your physical and mental health! Winter is coming.
EDIT> I'm a physics and biology student. I am not completely unaware of the science.
