In brief: MONONUCLEOSIS
Primary infection last about 2 weeks but ebv remains for life with intermittent shedding from the nasopharynx.
Infection can occur from kissing asymptomatic person who is shedding the virus.

In brief: At least a few weeks
Mononucleosis is caused by the epstein barr virus(ebv).
Most contract the virus in early childhood in an illness similar to a common cold. When the first exposure to ebv occurs in adolescence and beyond, the person gets mononucleosis. A person is most infectious in the first few weeks after the illness. Ebv remains in the body for life and can be transmitted to others through exchanging saliva.

In brief: Weeks
Individuals may shed epstein barr virus and cytomegalovirus (the two most common viral causes of mononucleosis), for weeks after their symptoms have resolved.
