What Is Mononucleosis? Causes, Symptoms & Treatment Options

Understanding Mononucleosis: An Overview

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.

Causes and Transmission of Mononucleosis

Primary Cause

Epstein-Barr virus (EBV) is the main cause. Once infected, individuals can carry the virus lifelong, with occasional reactivations.

How It Spreads

Transmission occurs via saliva, sharing drinks or utensils, and close personal contact. Less commonly, blood transfusions and organ transplants can transmit the virus.

Diagnosis: How Healthcare Providers Confirm Mono

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.

Effective Treatment and Management Strategies

Supportive Care

Rest, hydration, and over-the-counter pain relievers (acetaminophen or ibuprofen) alleviate symptoms. Avoid contact sports if spleen is enlarged to prevent injury.

Medical Interventions

In severe cases, corticosteroids may be prescribed to reduce swelling. Antibiotics are ineffective unless bacterial superinfection occurs.

When to Seek Medical Attention

If symptoms worsen, or if there is severe abdominal pain, difficulty breathing, or signs of spleen rupture, consult a healthcare professional immediately.

Prevention and Risk Reduction Tips

Prognosis and Long-term Outlook

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.
