Mononucleosis, commonly known as the “kissing disease”, is a viral infection that spreads through saliva and close contact with infected individuals.

While most people know some of the basics of mononucleosis, there are many interesting facts about this illness that often go unnoticed. In this article, we will explore 10 things you didn’t know about the kissing disease.

1. Mononucleosis is caused by the Epstein-Barr virus

The Epstein-Barr virus (EBV) is a member of the herpes virus family and is the primary cause of mononucleosis. The virus is highly contagious and spreads through close contact with an infected person’s saliva or other bodily fluids.

EBV can also cause other illnesses, such as some types of cancer and chronic fatigue syndrome.

2. The kissing disease is most common in young adults

While mononucleosis can affect individuals of all ages, it is most common in teenagers and young adults. In fact, up to 50% of people who get mononucleosis are between the ages of 15 and 24.

This is likely due to the fact that this age group tends to be more socially active and come into closer contact with others.

3. Mononucleosis symptoms can be mistaken for other illnesses

Mononucleosis symptoms can often be mistaken for other illnesses, such as the flu and strep throat. Common symptoms include fever, sore throat, swollen glands, fatigue, and muscle aches.

However, in some cases, individuals with mononucleosis may not experience any symptoms at all.

4. The majority of people who get mononucleosis make a full recovery

While the symptoms of mononucleosis can be quite uncomfortable, most people who get the illness make a full recovery within a few weeks to a few months.

However, some individuals may experience prolonged fatigue or other symptoms for up to six months following the initial illness.

5. Mononucleosis can cause your spleen to swell

One of the more serious complications of mononucleosis is splenomegaly, or swelling of the spleen. This can occur in up to 50% of cases and can cause abdominal pain, tenderness, and an increased risk of rupture.

Individuals with mononucleosis are often advised to avoid contact sports and heavy lifting until their spleen returns to its normal size.

6. You can still spread mononucleosis even if you have no symptoms

People with mononucleosis can spread the virus to others through saliva for up to six months after the initial infection, even if they have no symptoms.

This is why it is important for individuals with mononucleosis to take precautions to avoid spreading the virus to others.

7. There is no specific treatment for mononucleosis

There is no specific treatment for mononucleosis, as it is a viral infection that will typically resolve on its own. Treatment generally involves managing symptoms, such as with fever reducers, gargling with salt water for a sore throat, and rest.

In severe cases, hospitalization may be necessary to manage complications such as dehydration or an enlarged spleen.

8. Mono can be diagnosed with a simple blood test

Diagnosis of mononucleosis typically involves a simple blood test that checks for the presence of the Epstein-Barr virus antibodies in the blood. This test is usually done in a doctor’s office or lab.

9. Some people may be more susceptible to mononucleosis than others

While anyone can get mononucleosis, some individuals may be more susceptible to the illness than others. This may be due to certain genetic factors or a weakened immune system.

Additionally, individuals who come into close contact with others through activities such as sharing drinks or kissing may be at a higher risk of contracting the virus.

10. There are ways to lower your risk of getting mononucleosis

While there is no guaranteed way to avoid getting mononucleosis, there are some steps you can take to lower your risk.

This includes avoiding close contact with individuals who are sick, avoiding sharing drinks, and practicing good hygiene such as washing your hands frequently and avoiding touching your face. Additionally, some research suggests that getting enough sleep and maintaining a healthy diet may help boost immune function and lower the risk of getting sick.
