Mononucleosis is a contagious viral infection mainly caused by the Epstein-Barr virus (EBV). It commonly affects teenagers and young adults, spreading through saliva and close contact. Although often self-limited, proper medical guidance ensures effective management.
Epstein-Barr virus (EBV) is the main cause. Once infected, individuals can carry the virus lifelong, with occasional reactivations.
Transmission occurs via saliva, sharing drinks or utensils, and close personal contact. Less commonly, blood transfusions and organ transplants can transmit the virus.
Diagnosis involves blood tests such as the monospot test and CBC, which detect atypical lymphocytes or EBV antibodies. Clinical evaluation and symptom history are also critical.
Rest, hydration, and over-the-counter pain relievers (acetaminophen or ibuprofen) alleviate symptoms. Avoid contact sports if spleen is enlarged to prevent injury.
In severe cases, corticosteroids may be prescribed to reduce swelling. Antibiotics are ineffective unless bacterial superinfection occurs.
If symptoms worsen, or if there is severe abdominal pain, difficulty breathing, or signs of spleen rupture, consult a healthcare professional immediately.
Most people recover fully within 2–4 weeks. Some may experience prolonged fatigue. EBV remains dormant in the body, with rare reactivation. Proper medical care supports a swift recovery.
