Infectious mononucleosis

Viral infection that causes swollen lymph nodes and a sore throat. Also called glandular fever.


A system disease caused by the Epstein-Barr virus. Symptoms include fever, fatigue, swollen lymph glands, and sore throat. Recovery may be slow, taking several weeks or months.


An infectious disease where the body has an excessive number of white blood cells.


Acute infection, caused by the Epstein-Barr herpes vims and most common among young people; it is not highly contagious. Symptoms include fever, swollen lymph glands, sore throat, enlarged spleen and liver, abnormal liver function, fatigue, and malaise. Treatment is symptomatic, including bed rest to prevent spleen rupture or other spleen or Ever complications. One attack usually confers immunity. Also called glandular fever; kissing disease.


A usually mild viral disease common among young people. Symptoms include fever, sore throat, swollen lymph glands, headache, and fatigue. More severe cases may affect the spleen and liver.


An acute viral disease characterized by fever, sore throat, and swollen glands. Infectious mononucleosis is usually caused by the Epstein-Barr virus (EBV), but may also be caused by the cytomegalovirus (CMV). Both viruses are members of the herpes family. Infectious mononucleosis can be transmitted in saliva, via airborne infectious droplets, or via blood transfusion. Because of the transmission via saliva, mononucleosis is sometimes called “the kissing disease.”


An acute infectious disease caused by the Epstein-Barr virus (EBV), a member of the herpesvirus group. It is most common in the U.S. in people between 15 and 25 years of age (i.e., in high school- and college-age adolescents and young adults); beyond that age, most people are immune to EBV. The disease is sometimes referred to colloquially as the “kissing disease” because of its mode of transmission from person to person.


A viral infection that causes the lymph nodes, tonsils, and spleen to become swollen and tender.


An abrupt viral infection, often referred to as glandular fever, recognized by elevated body temperature, a sore throat, and enlarged lymph nodes.


The Epstein–Barr virus is responsible for the infection. It spreads through saliva, often from close personal interactions like kissing, or potentially from shared items like cups or utensils.


The virus proliferates in the body’s lymphocytes, also known as mononuclear cells. While an infection during early childhood might not show any symptoms, they frequently manifest during adolescence or early adulthood. Initial symptoms include a fever and headache, which are then followed by swollen lymph nodes, especially in the neck, and a significant sore throat. In some rare instances, tonsil swelling can impede breathing. The spleen might also enlarge, and there’s a possibility of liver inflammation, which can occasionally lead to jaundice.


The diagnosis of this condition is typically based on the symptoms and a blood test, as affected lymphocytes display an unusual appearance. Recovery generally spans four to six weeks, with rest being the primary remedy. In uncommon situations, corticosteroid medications might be administered to alleviate intense tonsil inflammation, especially if it interferes with breathing. Until the spleen has reverted to its usual size, individuals should steer clear of contact sports. After recovering, it’s common for individuals to experience feelings of depression, fatigue, and daytime drowsiness for the subsequent two to three months.


A contagious illness of unidentified cause, presenting symptoms like fever, sore throat, swollen lymph nodes, particularly at the back of the neck, and an elevated count of unusual mononuclear cells in the blood. A rash resembling German measles might appear, along with an enlarged spleen. Typically, patients recover fully, and complications are uncommon. The disease, possibly viral, often appears in mild epidemic waves and mainly affects children and young adults. Its incubation period ranges from five to twelve days. If the diagnosis is uncertain, the Paul-Bunnell blood test can usually confirm it. The primary treatment is bed rest during the feverish phase. However, the disease can cause significant fatigue, leading to an extended recovery period. It’s also referred to as glandular fever.
