, myalgia, fatigue, diarrhea, stomach cramps and vomiting which only lasted 1 day; about a month later I also developed aphthous ulcers. im uncircumcized which from what I have read increases the risk of transmission. what are my chances of contracting this horrible disease? what does this 1/2000 risk per exposure really mean? and how much would this decrease given the fact that I am uncircumcized.
