Hi, sorry about your problem. I agree with the last post. You probably mean pinworm which is a white small worm. Yes it gets everywhere. So, once you are treated you will have to ask the doctor how to properly clean the linen, and anything else in the area, your clothes. The eggs get everywhere and are very very easily transmitted. I don't think the medicine has had time to get rid of the infection yet either.
Yes, they are HIGHLY contagious. They can be spread by linens, bedding, towels, toilet seats, etc.
