Earlier today I saw something large on the road and got out of my car to kick it to the ditch. This was in a rural area with farm fields on either side of the road, outside a small town in Ontario, Canada. The object turned out to be a large, dirty-looking blanket. I didn't touch it with my hands but my boots and possibly the bottom of my pants touched it, especially as I kicked it around a bit to make sure there was nothing in it. My question is this: is it at all possible that I could have gotten something contagious on my clothing? I'm not worried about myself at all, but later in the day I sat in a movie theatre and then in a restaurant, and I need to know that I can't have brought something dangerous to those places and infected anyone. I'm really worried about causing inadvertent harm this way, particularly as I wouldn't have any way of knowing afterward. I need to know if I should contact some sort of authorities or if this is just an over-reaction - I didn't see anything on my clothes afterward but I have a strong sense of social responsibility and want to be sure nobody's getting anything bad from that blanket (especially since I was in public places afterward.)
