Adolescents with mono face elevated risk of spleen rupture during physical activity

Adolescents and college students who contract mononucleosis must pause their physical activities to protect their internal organs. The infection causes the spleen to enlarge, creating a vulnerability that standard athletic rules do not address.

Dr. Alicia Bazzano, a physician at MedStar Health, explained that mono symptoms often include sore throat, fever, and fatigue. While these signs resemble other common illnesses, the physical changes inside the body present a specific danger for active youth.

Bazzano stated that patients should not participate in sports while infected. She warned that physical exertion can lead to spleen injuries. The spleen sits beneath the rib cage and is susceptible to rupture when it is swollen.

The risk is highest during the initial stages of the illness and the recovery period. Students who return to the field too soon face a greater chance of trauma to the organ. This can require medical intervention to stop internal bleeding.

Bazzano noted that other seasonal illnesses, such as influenza and meningitis, also require careful monitoring. She advised families to take symptoms seriously rather than assuming they are minor seasonal colds. The advice applies specifically to older children who socialize in close quarters and share drinks.

The warning comes as the new school year begins and cold and flu season ramps up. Health officials recommend that students with confirmed mono rest until medical clearance is granted. This precaution helps prevent serious complications during the peak of respiratory infections.
