Mononucleosis
Mononucleosis, also known as glandular fever, is a viral infection that commonly affects young adults. The disease is caused by the Epstein-Barr virus (EBV), which is a member of the herpesvirus family. Symptoms of mononucleosis include fever, fatigue, sore throat, swollen lymph nodes, and muscle aches. The illness is usually self-limiting, and most people recover within a few weeks with rest, fluids, and over-the-counter pain relief medication. However, in some cases, complications such as an enlarged spleen or liver can occur, and medical attention may be required. Mononucleosis is predominantly transmitted through kissing, sharing utensils or cups, or other close contact with an infected person. There is no specific treatment for mononucleosis, but avoiding contact with infected individuals and practicing good hygiene can help reduce the risk of contracting the virus.
Symptoms of Mononucleosis
What are the common symptoms of mononucleosis?
Common symptoms of mononucleosis, also known as mono or the "kissing disease," include fatigue, sore throat, fever, swollen lymph nodes, swollen tonsils, headache, skin rash, and muscle aches. Symptoms may not appear immediately after infection, and can take between 4 to 6 weeks to develop.
What causes mononucleosis in the body?
Mononucleosis is caused by the Epstein-Barr Virus (EBV), which is a member of the Herpesvirus family. EBV is highly contagious and can be transmitted through contact with an infected person`s saliva, such as through kissing, sharing utensils or cups, or coughing and sneezing.
How is mononucleosis spread among people?
Mononucleosis is spread among people through contact with saliva or mucus from an infected person. The virus can be present in the saliva for up to 18 months after an initial infection and can also be spread through blood transfusions or organ transplants.
Is fever a common symptom of mononucleosis?
Fever is a common symptom of mononucleosis, usually in the range of 101 to 104°F, along with other symptoms such as sore throat, fatigue, and swollen lymph nodes. However, not everyone infected with EBV will have a fever.
Can mononucleosis lead to enlargement of the liver and spleen?
Yes, mononucleosis can lead to enlargement of the liver and spleen, which can cause discomfort or pain in the upper abdomen. In rare cases, this enlargement can be severe enough to cause rupture of the spleen, which can be life-threatening. It is important to avoid physical activity or contact sports if you have mononucleosis, to reduce the risk of spleen rupture.
Diagnosis of Mononucleosis
What are the common diagnostic tests for mononucleosis?
The common diagnostic tests for mononucleosis include a physical exam, blood tests, and a mono spot test. The physical examination would check for common symptoms such as swollen lymph nodes, tonsils, and spleen. Blood tests would look for an increase in white blood cells, commonly seen in infectious mononucleosis caused by the Epstein-Barr virus (EBV), as well as the presence of antibodies against the virus. The mono spot test is a simple blood test that looks for heterophile antibodies which are commonly produced by the body in response to a viral infection.
How is mononucleosis diagnosed in a laboratory?
Mononucleosis can be diagnosed in a laboratory through a variety of blood tests. These tests measure the levels of white blood cells and check for the presence of antibodies associated with the Epstein-Barr virus. The most common tests used to diagnose mononucleosis include the monospot test which looks for heterophile antibodies, and the EBV-specific antibodies test which looks for specific antibodies associated with the Epstein-Barr virus.
Can mononucleosis be diagnosed with a physical examination alone?
A physical examination alone cannot completely diagnose mononucleosis. While a physical exam can help identify common symptoms such as swollen lymph nodes, tonsils, and spleen, it cannot provide a definitive diagnosis. Further testing, such as blood tests, would be necessary to confirm the diagnosis.
Is a blood test conclusive for the diagnosis of mononucleosis?
A blood test can be helpful in the diagnosis of mononucleosis, but it is not always conclusive. While an increase in white blood cells is commonly seen in individuals with infectious mononucleosis caused by EBV, it can also be seen in other viral infections. The presence of heterophile antibodies and specific antibodies associated with the Epstein-Barr virus can also increase the likelihood of a mononucleosis diagnosis, but it is not always definitive.
What other tests are used to confirm a diagnosis of mononucleosis?
Other tests that may be used to confirm a diagnosis of mononucleosis include a throat culture to rule out a bacterial infection, a liver test to check for liver inflammation, and a spleen ultrasound to check for spleen enlargement. In rare cases, a lymph node biopsy may be necessary to confirm the presence of EBV-infected cells.
Treatments of Mononucleosis
What are the common medications used to manage Mononucleosis?
The common medications used to manage Mononucleosis include nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, acetaminophen or aspirin to reduce fever and pain. For severe sore throat, corticosteroids like prednisone may be prescribed. Antivirals like acyclovir are also used in some cases to target the Epstein-Barr virus that causes Mononucleosis.

Is bed rest considered a part of Mononucleosis treatment?
Bed rest is considered a part of Mononucleosis treatment as it helps the body to recover by conserving energy and reducing stress on the immune system. It is also recommended to avoid strenuous activities that can trigger symptoms and take plenty of fluids to stay hydrated.

At what stage of Mononucleosis is an antibiotic prescribed?
Antibiotics are not prescribed for Mononucleosis as it is a viral infection that cannot be treated with antibiotics. However, if a bacterial infection occurs as a complication of Mononucleosis, such as strep throat, antibiotics may be prescribed to treat the bacterial infection.

How can symptoms like fever and sore throat be managed during Mononucleosis?
Symptoms like fever and sore throat can be managed during Mononucleosis by taking over-the-counter pain relievers like acetaminophen or ibuprofen, resting and avoiding strenuous activities, drinking plenty of fluids, gargling with salt water to relieve sore throat, and using throat lozenges or sprays for temporary relief. It is important to avoid sharing utensils or drinks to prevent the spread of the virus to others.

Can Mononucleosis be cured with medication alone or does it require other forms of treatment?
Mononucleosis cannot be cured with medication alone as it is a viral infection that needs time for the body to fight off the virus. Treatment mainly involves managing symptoms and allowing the body to recover naturally. It is important to get plenty of rest, take pain relievers for fever and sore throat, drink enough fluids, and avoid strenuous activities until symptoms subside. It is also important to follow good hygiene practices to prevent the spread of the virus to others. Source: Medical News Today (https://www.medicalnewstoday.com/articles/324726)
