-
The child meets other exclusion criteria (see Conditions Requiring Temporary Exclusion in Chapter 4 of
Managing Infectious Diseases in Child Care and Schools: A Quick Reference Guide, 7th Edition ).
Readmit to educational setting?

-
When exclusion criteria are resolved, the child is able to participate, and staff members determine they can care for the child without compromising their ability to care for the health and safety of the other children in the group.
-
School-aged children and adolescents should avoid strenuous activity and contact sports for at least 4 to 6 weeks after symptoms start as the spleen may temporarily enlarge and is at risk of rupture with physical impact. Clearance for contact sports will depend on a health practitioner’s assessment of ongoing symptoms and size of the spleen. It may take 3 to 6 months or longer for a child to regain their full stamina, strength, and fitness.
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. Some individuals might experience ongoing symptoms, such as significant fatigue or malaise, fever, muscle aches, or cognitive fog. These individuals may benefit from class modifications such as adjusted assignments, extended deadlines, or remote learning, depending on the severity of their symptoms.
-
General exclusion of those with mononucleosis is not practical.
