Dumb question but since the average person is indoors 90% of the time, does the outdoor condition make much difference?
Humidity gets into the house. I have humidity gauges, and when it rains, it gets much more humid in the house. The humidity makes the air more dense, causing the virus to fall to the floor quicker, and stay on the floor. Dry air, it floats around, into the lungs. I suppose heat and sunlight help to destroy its structure.
