mono can be transmitted by "intimate" contact but not necessarily from sexual activity which can involve face-to-face contact even if you restrain from kissing. the ebv virus (the cause of mono) has a long incubation period (many weeks) so you have most likely been exposed already. exposure to any infectious disease does not automatically mean you will get it since many people already have had mono in their lives and did not know it. because of past exposure or a mild form of mono that was not diagnosed in the past your sexual partner may have protective antibodies. mono is not considered a sexually transmitted disease but the closeness of this type of intimate encounter could spread the virus to a vulnerable person. or not. victims of mono are often very tired and exhausted so they may not be overly-interested in sexual activity but if your wife is feeling better (mono may not last more than a week in some mild cases) you can make a mutual decision keeping in mind that you were most likely exposed before you knew she had mono.
my wife has mono. can it be sexually transmitted without kissing? how long before we can have unprotected sex?
