Mononucleosis, more commonly known as mono, is a viral infection caused by the Epstein-Barr virus (EBV). It is most common in teens and young adults and often goes away on its own without treatment. Symptoms of mono include fever, sore throat, swollen lymph nodes, fatigue, and muscle aches or weakness. These symptoms can last for several weeks and can interfere with daily life. While mono is usually not serious, there is a risk of developing complications such as an enlarged spleen, which can lead to pain and bleeding inside the belly.

What You'll Learn
Mono is caused by the Epstein-Barr virus (EBV)
Mononucleosis, or mono, is a viral infection that causes fever, a sore throat, and swollen lymph glands, most often in the neck. Mono is caused by the Epstein-Barr virus (EBV), which is extremely common. EBV is a virus that is often seen in children, adolescents, and young adults, and it is from the herpes family. About 95% of Americans are infected by age 35, but not everyone who has the virus develops mono symptoms—some people only carry the virus.
EBV infection may cause an extended, flu-like illness commonly known as infectious mononucleosis (mono). The virus attacks different parts of the body and can leave an infected person feeling ill for weeks. Symptoms of mono include extreme fatigue, body aches, headaches, and a sore throat. In some cases, mono may also cause a measles-like rash on the face or body, tiny red spots or bruise-like areas inside the mouth, and soreness in the upper left abdomen due to an enlarged spleen.
Signs of mono usually appear four to six weeks after infection with EBV and can last for four weeks or longer. Most people feel better after two to four weeks but may experience lingering fatigue for several weeks or even months afterward. It is important to get enough rest and fluids during this time and to avoid strenuous activities to prevent a ruptured spleen.
While mono is typically caused by EBV, it is important to note that other viruses can also cause mono, such as cytomegalovirus (CMV). Additionally, not everyone infected with EBV will develop mono. EBV can remain in the body for years without causing any problems and may not pose a risk of infection to others. However, in certain situations, such as in patients with weakened immune systems, reactivation of EBV can occur.

Symptoms include body aches, fever, and fatigue
Mononucleosis, or mono, is a viral infection caused by the Epstein-Barr virus (EBV). It is sometimes referred to as the "kissing disease" because it is spread through saliva and can be transmitted through kissing. However, it can also be spread by sharing food utensils or drinks with an infected person. While mono is most common in teens and young adults, about 95% of Americans are infected with the EBV by age 35. Fortunately, mono usually goes away on its own within a few weeks of rest and proper hydration.
Mono symptoms typically appear four to six weeks after infection and can last for four weeks or longer. The early symptoms of mono are similar to those of the flu and may include:
- Extreme fatigue
- Body aches
- Fever
- Headache
- Sore throat
- Chills
- Swollen lymph nodes in the neck, armpits, or groin
- Loss of appetite
- Muscle weakness
In some cases, mono may also cause:
- A measles-like rash on the face or body
- Tiny red spots or bruise-like areas inside the mouth, especially on the roof of the mouth (palate)
- Soreness in the upper left abdomen due to an enlarged spleen
- Mild liver inflammation (hepatitis)
- Jaundice, resulting in a yellowing of the skin and eyes
It is important to note that mono can cause the spleen to swell, and physical activity or contact sports should be avoided while infected and for several weeks afterward to prevent spleen rupture.

It is nicknamed the 'kissing disease' as it spreads through saliva
Mononucleosis, or mono, is a viral infection that causes fever, a sore throat, and swollen lymph glands, most often in the neck. It is caused by the Epstein-Barr virus (EBV), which is transmitted through bodily fluids, including saliva.
Mono is nicknamed the "kissing disease" because it is spread through saliva. Kissing is a common way to transmit the virus, but it can also be spread by sharing drinks, food, or utensils with someone who has mono. The virus can live for several hours outside the body, and it may persist in an infected person's saliva for months.
In addition to kissing, mono can be spread through other means, such as blood transfusions, coughing, sneezing, or sexual contact. However, it is not as contagious as some other infections, like the common cold.
The Epstein-Barr virus is very common, and about 95% of Americans are infected by age 35. However, not everyone who has the virus develops mono symptoms—some people only carry the virus. For those who do develop symptoms, mono usually goes away on its own without treatment, although it can cause extreme fatigue, body aches, and other symptoms that can interfere with daily life.

Mono can cause an enlarged spleen, which may rupture
Mononucleosis, or mono, is a viral infection caused by the Epstein-Barr virus (EBV). It is most common in teens and young adults and typically goes away on its own without treatment. However, mono can cause various symptoms, including muscle aches and soreness in the upper left abdomen due to an enlarged spleen. While mono usually resolves within a few weeks, it can sometimes lead to complications, including an enlarged spleen, which may rupture.
An enlarged spleen is a rare but possible complication of mono. The spleen is a small organ located in the upper left abdomen, and it can become enlarged due to various conditions, including mono. In the context of mono, an enlarged spleen is typically not painful but can cause discomfort and a feeling of fullness in the left upper abdomen. This enlargement is usually mild and resolves without any specific treatment. However, in rare cases, it can lead to more serious complications.
The main concern with an enlarged spleen is the risk of rupture. While this is uncommon, it can be life-threatening. A ruptured spleen can cause severe pain and bleeding in the abdomen, requiring immediate medical attention and often emergency surgery. Therefore, it is crucial for individuals with mono to be cautious and avoid activities that could increase the risk of spleen rupture. This includes contact sports, strenuous exercise, and any activity that involves direct impact to the abdomen.
To reduce the risk of spleen rupture, doctors recommend that individuals with mono avoid contact sports and strenuous activities for at least one month after their symptoms have resolved. Getting plenty of rest and staying well-hydrated are also essential for recovery. Additionally, it is important to be vigilant for any signs or symptoms that could indicate a ruptured spleen, such as severe abdominal pain, lightheadedness, or confusion. If any of these symptoms occur, immediate medical attention is necessary.
In summary, mono can cause an enlarged spleen, which, in rare cases, may rupture. While most cases of mono resolve without complications, it is crucial to be aware of this potential risk and take the necessary precautions to prevent spleen rupture. This includes avoiding strenuous activities, staying well-rested and hydrated, and seeking medical attention if any concerning symptoms develop. By following these guidelines, individuals with mono can effectively manage their condition and reduce the risk of complications.

It is most common in teens and young adults
Mononucleosis, or mono, is a viral infection caused by the Epstein-Barr virus (EBV). It is often referred to as "the kissing disease" because it can be spread through kissing, but it is also spread through shared utensils or drinks. Mono is most common in teens and young adults, and it is estimated that about 95% of Americans are infected with EBV by age 35. While mono usually goes away on its own within a few weeks of rest and fluids, it can cause various symptoms, including muscle aches and weakness, that can interfere with daily life.
The symptoms of mono typically appear 4 to 6 weeks after infection with EBV and can last for 4 weeks or longer. Most people feel better after 2 to 4 weeks but may experience fatigue for several weeks or even months afterward. In rare cases, mono can cause more severe complications, such as an enlarged spleen, which can rupture and lead to pain and bleeding inside the belly, requiring emergency surgery. Other possible but rare complications include nervous system problems such as Guillain-Barré syndrome, meningitis, seizures, and Bell palsy, which can cause damage to the nerve that controls the muscles in the face.
The early symptoms of mono are similar to those of the flu or strep throat and may include severe fatigue, a headache, a sore throat, chills, and a fever. Muscle aches are also a common symptom of mono and can be treated with nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen. While mono is usually not serious, it is important to get plenty of rest and fluids and avoid strenuous activity to prevent a ruptured spleen.
While mono is most common in teens and young adults, it is important to note that infants and young children can also be infected with EBV. However, they typically experience mild or no symptoms, and the infection often goes undiagnosed. In rare cases, mono during pregnancy can increase the risk of miscarriage and premature labor, and there is a slight chance of passing the virus to the fetus or a breastfeeding baby. Therefore, it is crucial to consult a healthcare provider if experiencing any symptoms of mono during pregnancy.
