Understanding Other Infectious Mononucleosis

Infectious mononucleosis, commonly known as "mono," is a viral infection caused by the Epstein-Barr virus (EBV). However, there are other types of infectious mononucleosis that are caused by different viruses.

Here are some of the other types of infectious mononucleosis:

  1. Cytomegalovirus (CMV) mononucleosis: This type of mononucleosis is caused by the CMV virus. It is similar to EBV mononucleosis in terms of symptoms, but it is more common in people with weakened immune systems.
  2. Toxoplasmosis: This is a parasitic infection that can cause mononucleosis-like symptoms, including fatigue, fever, and swollen lymph nodes. It is usually spread through contact with cat feces or contaminated food.
  3. HIV: HIV can also cause mononucleosis-like symptoms, as it weakens the immune system and makes the body more susceptible to infections.
  4. Hepatitis A, B, and C: These types of viral hepatitis can cause symptoms similar to those of mononucleosis, including fatigue, fever, and abdominal pain.

It is important to understand that while these infections may cause similar symptoms, they are caused by different viruses and require different treatments. If you are experiencing symptoms of mononucleosis, it is important to see a healthcare provider for an accurate diagnosis.

Some general tips for preventing infectious mononucleosis include:

  • Washing your hands frequently with soap and water
  • Avoiding sharing drinks, utensils, and other personal items with others
  • Getting enough rest and maintaining a healthy lifestyle to boost your immune system

If you have been diagnosed with mononucleosis, it is important to rest and take care of yourself. While there is no specific cure for mononucleosis, plenty of rest, fluids, and over-the-counter pain relievers can help manage symptoms.


While EBV mononucleosis is the most common type of infectious mononucleosis, there are other types of infections that can cause similar symptoms. By understanding the different types of mononucleosis and taking steps to prevent infection, you can help protect yourself and those around you.
