Mononucleosis, commonly known as glandular fever or mono, is a viral infection caused by the Epstein-Barr virus (EBV). While children often experience mild symptoms, teenagers and adults can become more severely ill. Once infected, a person develops immunity and cannot contract mononucleosis again.
Causes
Mononucleosis is primarily caused by the Epstein-Barr virus (EBV), which is highly contagious and spreads through saliva. Transmission typically occurs through close contact, such as kissing, sharing drinks, or other activities involving saliva exchange.
Symptoms
Symptoms of mononucleosis can vary depending on age. Children often have mild, cold-like symptoms, while teenagers and adults may experience more pronounced symptoms, including:
- Sore Throat: Often severe, making swallowing difficult.
- Fatigue: Persistent and overwhelming tiredness.
- Fever: Elevated body temperature.
- Headache: Pain in the head.
- Loss of Appetite: Reduced desire to eat.
- Body Aches: Muscle and joint pain.
- Swollen Lymph Nodes: Enlarged and tender lymph nodes in the neck, armpits, and groin.
- Enlarged Tonsils: Tonsils may be swollen and covered with a grayish-white coating.
Less common symptoms include:
- Swelling around the Eyes:
- Skin Rash:
- Nausea:
- Enlarged Liver and Spleen: The liver and spleen may become temporarily enlarged, sometimes causing jaundice (yellowing of the skin and eyes).
Symptoms typically last for two to three weeks, but fatigue can persist for several months.
When to Seek Medical Attention
Consult a healthcare provider if you experience:
- Sore throat and fever lasting more than two days without other cold symptoms.
- Difficulty swallowing.
- Fever that returns after being fever-free for at least one day.
- Underlying medical conditions or medications that affect the immune system.
Seek immediate medical attention if you experience severe abdominal pain, which could indicate a ruptured spleen.
Diagnosis
Diagnosis typically involves:
- Physical Examination: Evaluation of symptoms and examination of the throat, lymph nodes, and abdomen.
- Blood Tests:
- Complete Blood Count (CBC): To check for elevated white blood cell count.
- Monospot Test: A rapid test to detect antibodies specific to EBV.
- EBV Antibody Tests: More specific tests to confirm EBV infection.
- Throat Swab: To rule out strep throat, as symptoms can be similar.
Treatment
Mononucleosis is a viral infection, so antibiotics are ineffective. Treatment focuses on relieving symptoms:
- Rest: Get plenty of rest to allow the body to recover.
- Hydration: Drink plenty of fluids to prevent dehydration.
- Pain and Fever Relief: Over-the-counter pain relievers like acetaminophen (paracetamol) or ibuprofen can help alleviate pain and fever.
- Gargling with Salt Water: Can soothe a sore throat.
- Avoid Strenuous Activity: Refrain from strenuous activities, especially contact sports, for at least one month to prevent spleen rupture.
- Avoid Alcohol: Alcohol should be avoided until full recovery, as the liver may be affected.
Prevention
- Avoid Sharing Personal Items: Do not share drinks, utensils, or toothbrushes with others.
- Practice Good Hygiene: Wash hands frequently to prevent the spread of infection.
Complications
Complications from mononucleosis are rare but can include:
- Spleen Rupture: Enlarged spleen is susceptible to rupture, especially with trauma.
- Liver Inflammation (Hepatitis):
- Anemia:
- Thrombocytopenia: Low platelet count.
- Neurological Complications: Such as meningitis or encephalitis (rare).
Takeaway
Mononucleosis is a common viral infection that can cause significant fatigue and discomfort. While there is no specific cure, rest, hydration, and symptom management can help individuals recover fully. Avoiding strenuous activity is crucial to prevent spleen rupture.
