What are the incubation and contagious periods?

Prevent children from sharing food

School-aged children should avoid contact sports if they have an enlarged spleen until the spleen is no longer enlarged.
Comments
-
Most people get the infection in early childhood when signs or symptoms are mild and the disease goes undiagnosed. However, rarely, the disease can be severe, particularly in adolescents.
-
General exclusion of those with mononucleosis is not practical.
