Will i get mono from my boyfriend if he has mono?

Maybe: The majority of adults have mono in childhood and are immune. For those that are not, the illness is harsh. The contagious period begins days before the first symptoms and lasts 3 weeks in most, longer in some.You can be supportive,but less intimate, and might avoid it.Yet you are likely incubating it already if susceptible. I'd probably take my chances unless I wanted an excuse to take off.
