When cold weather arrives, more and more people are going into smaller and smaller spaces. Shorter days, means shorter time to go errands which results in more people in a given space, so increase in likelihood of increased infections. And there are so many people who will not stay home when they feel ill - they are just running a couple of errands and infecting people as they go. Look at how many will have a mask on BELOW their nose.
The infection rate doesn't have to go up, but that requires everyone to do their part, stay home if feeling ill, wear a mask whenever going out into public, wash hands frequently, disinfect, etc.
