Do I have an infection and if so how do I get rid of it?

Yes you have a low grade infection caused by stupid people not washing their hands and touching things they aren't supposed to. Don't touch it yourself unless you've washed or used a hand sanitizer. You can clear that up quick enough with washing, drying and applying band-aid wash or bactine. They both contain benzalkonium chloride (benz-all) which is one of the best and fastest acting anti-infection products that you can buy over the counter.
