Mononucleosis: Symptoms, Causes, Diagnosis, and Treatment Options

Aug 13, 2024

The Human body is one of the most complicated machines and to ensure that it functions at its best, we must take good care of it.  While keeping up the pace with the rest of the world, sometimes we forget to take care of ourselves due to our busy schedules. We need to maintain hygiene and be extremely cautious against diseases that are communicable such as mononucleosis. It is a contagious infection caused by a herpes virus called Epstein-Barr which can be transmitted through body fluids.  

What is mononucleosis?

It is a contagious disease most commonly caused by Epstein-Barr virus (EBV). There are other viruses too that can cause this disease. It is also known as mono or the kissing disease because in most cases it is commonly transmitted via saliva. It is an infection that is prevalent among teens and young adults with all the signs and symptoms. However, young children have very few symptoms of mononucleosis and can go undiagnosed.

What are the Signs and Symptoms of Mononucleosis?

Symptoms of mononucleosis may vary as they can be mild or severe. It is a kind of disease that tends to grow gradually. You might be wondering, what are the symptoms of mononucleosis and how long does it last? It takes four to six weeks to get rid of this disease and the symptoms often appear 4 to 6 weeks after you get infected with EBV. These symptoms include:

  1. Extreme tiredness or fatigue.
  2. Fever.
  3. Sore throat.
  4. Headaches and body aches.
  5. Swollen lymph nodes in the neck and armpits.
  6. Swollen liver or spleen or maybe both.
  7. Skin rash.
  8. Liver problems.

In case, you are experiencing the above symptoms for two weeks or more then you must see your doctor without any further delays.

What Causes Mononucleosis?

About 90% of mononucleosis cases are caused by the Epstein-Barr virus. Other viruses and infections too can cause mononucleosis which are:

  1. Adenovirus
  2. Cytomegalovirus
  3. Hepatitis A, hepatitis B & hepatitis C.
  4. Herpes simplex virus.
  5. Human immunodeficiency virus.
  6. Rubella.
  7. Toxoplasmosis.

How is Mononucleosis Diagnosed?

To make a diagnosis, the doctor will assess your symptoms to confirm mononucleosis. Mentioned below are the types of blood tests to diagnose mononucleosis.

  1. Complete blood count – When there is a presence of certain types of white blood cells, it supports the diagnosis.
  2. Antibody tests – Identifying the EBV in one’s blood also helps in mononucleosis diagnosis.
  3. Heterophile antibody test - If the test is positive, it means you have mononucleosis.

What Complications Can Rise from Mononucleosis?

Sometimes mononucleosis can lead to serious complications, which are:

  1. Enlargement of the spleen – The spleen is a small organ that filters blood to help destroy microorganisms and get rid of damaged red blood cells. In extreme cases, there might be sharp and sudden pain in the left side of your upper abdomen. You need medical attention or maybe surgery in such conditions.
  2. Liver issues – You may face liver-related problems led by mononucleosis disease. These problems may occur with Hepatitis & Jaundice.

What are The Treatments for Mononucleosis?

The treatment depends on your age, symptoms and how severe the condition is. Since there is no antiviral medication the treatment focuses on making you feel better by relieving the symptoms. The self-care plan involves:

  1. It is a disease that makes your body weak and sleeping can help your body to fight the infection.
  2. Mononucleosis treatment suggests that keeping your body hydrated all the time also helps your body fight the infection.
  3. Anti-inflammatory drugs help to ease fever, inflammation, headaches and muscle aches.
  4. You can gargle with salt water to soothe sore throat.
  5. Since physical activities can put too much pressure on your spleen, it would be wise to avoid sports because it can increase the risk of rupturing your spleen.

In most cases, mononucleosis does not cause much serious problems. But it does not mean that attention or treatment is not required. It is a contagious disease with symptoms that can be very unpleasant if it takes time to recover. Keeping in mind the fact that there is no cure. As a part of the treatment plan, one needs lots of rest, drink plenty of liquids and take pain relievers to help you feel better.
