Hello, My name is XXXXXXX and I am an 18-year-old senior who just graduated from high school. My twin brother and I are going to be moving to college in less than a month, but I am afraid that we may have contracted mononucleosis from our friend. Yesterday, we all played a few brass instruments together and swapped around; only until later did we remember that he had mono last year. I don t know when he had mono exactly, but he tells me that it was over a year-and-a-half ago and assures me that we will not be infected. Still, I can t help feeling that we will contract the disease, ruining our first crucial weeks at college. Any answer to my query will be appreciated. Thank you again.
