In the last few weeks my roommate became sick. We smoke together, but once he started getting sick I started lighting the end of the pipe with a lighter. The last time we smoked together was 8/20 and the next day he developed sores on the inside of the mouth. He took a culture test and confirmed that it was Oral Herpes. It has been five days and his symptoms have cleared. I have developed no symptoms at all (fever, swollen gums, sores on the inside of the mouth and the outside of the mouth). I will be getting tested on Monday but I am really scared that I contracted it. What are the odds that I could have contracted it this way despite the "sanitizing" pf the pipe? Thank you.
