Abstract:
Infectious mononucleosis is an extremely common problem in the athletic population. "Mono" occurs in 3% of college students. Diagnosing infectious mononucleosis requires an understanding of the clinical features such as fever, lymphadenopathy, pharyngitis, and splenomegaly, as well as laboratory findings. The time at which these clinical features and laboratory abnormalities develop is also important to understand. Splenomegaly is common, but splenic rupture is very rare. Whether an athlete may return to activity usually relates to the presence of splenomegaly and the duration of the illness. Splenic rupture has not been reported after an individual has been ill for more than 3 weeks. This article provides an overview of infectious mononucleosis. The most common complications are reviewed and the management of these problems discussed. A practical approach to determining when an athlete may return to activity is presented.
Insights
Infectious mononucleosis, or "mono," is common in athletes. This overview helps manage the illness and guides safe return to play, focusing on symptoms and recovery time.
Area of Science:
- Sports Medicine
- Infectious Diseases
- Public Health
Background:
- Infectious mononucleosis (mono) is a prevalent condition affecting athletes.
- Diagnosis relies on recognizing clinical signs like fever, swollen lymph nodes, sore throat, and enlarged spleen, alongside lab results.
- Understanding the timeline of symptom and lab abnormality development is crucial.
Purpose of the Study:
- To provide a comprehensive overview of infectious mononucleosis in athletes.
- To review common complications and their management.
- To present a practical strategy for determining athlete return-to-activity timelines.
Main Methods:
- Literature review of infectious mononucleosis in the athletic population.
- Analysis of clinical features, laboratory findings, and temporal disease progression.
- Examination of factors influencing return to play, including splenomegaly and illness duration.
Main Results:
- Splenomegaly is a frequent finding, though splenic rupture is rare.
- No splenic ruptures have been reported after three weeks of illness.
- Return to activity is typically guided by the absence of splenomegaly and illness duration.
Conclusions:
- Effective management of infectious mononucleosis in athletes requires understanding its clinical presentation and diagnostic criteria.
- Complications should be recognized and managed promptly.
- A structured approach to return-to-play decisions is essential for athlete safety.
