Mononucleosis

How it Spreads 

• From person-to-person contact through kissing on the mouth or sharing objects contaminated with saliva (e.g., toys, toothbrushes, cups, or bottles).
• Possibly by blood transfusion or organ transplantation. 

Signs and Symptoms 

• Usually mild or no signs or symptoms, especially in young children
• Fever, sore throat, or fatigue
• Swollen lymph nodes
• Enlarged liver and spleen
• Rash may occur with those treated with amoxicillin or other penicillin

Prevention 

• Wash hands often for at least 15 to 20 seconds
• Avoid transfer or contact with saliva through kissing or sharing respiratory secretions (coughs or sneezes) directly or through contact with objects like food utensils, cups, bottles, or drink cans).
• People with signs and symptoms of mononucleosis should not donate blood
• Clean and sanitize toys and utensils before they are shared (i.e., after each child has used them)
• Ensure all children have their own toothbrushes, cups, and eating utensils
• Prevent children form sharing food
• Avoid kissing children on the mouth

Treatment 

• Most people get better in 2 to 4 weeks. You can help relieve symptoms by drinking fluids to stay hydrated, getting plenty of rest, taking over-the-counter medications for pain and fever
• See your healthcare provider if you have any questions or concerns about treatment options.
