I had a rash for a while and put off getting it checked till today because I now have a bad cold and the rash is spreading, my doctor told me that I have Mono, which was brought on by EBV.... She told me all this without a blood test..... I had a few questions about this... 1.) Can she be positive about what she said without a blood test??? 2.) Can you get Mono without having EBV? 3.) Does everyone have EBV, but it just effects some people and some it doesn't? and 4.) I work with food and want to know if I can go back to work, whether with the mono, or with the EBV?..... Thank You
