4 to 7 weeks: Lymph nodes and other symptoms usually show up 4 to 7 weeks after exposure to the epstein barr virus, which causes mononucleosis. They can occur sooner. People with mono are most infectious earlier in the disease, but can remain infectious up to 18 months. Transmission is mainly through saliva. Any infection of the mouth and throat can cause swollen lymph nodes in the neck, so see a doctor.
