Infectious Mononucleosis

Infectious mononucleosis, or "mono", is an infection caused by the Epstein-Barr virus. The virus spreads through saliva, which is why it's sometimes called "kissing disease." Mono occurs most often in 15 to 17-year-olds. However, you can get it at any age. Symptoms of mono include

Sometimes you may also have a swollen spleen. Serious problems are rare.

A blood test can show if you have mono. Most people get better in two to four weeks. However, you may feel tired for a few months afterward. Treatment focuses on helping symptoms and includes medicines for pain and fever, warm salt water gargles and plenty of rest and fluids.

Infectious Mononucleosis on Wikipedia

'''Infectious mononucleosis''' (also known as '''mono''', '''the kissing disease''', '''Pfeiffer's disease''', and '''glandular fever''') is a disease seen most commonly in adolescents and young adults, characterized by fever, sore throat and fatigue. It is caused by the Epstein-Barr virus (EBV) or the cytomegalovirus (CMV). It is typically transmitted through saliva or blood, often through kissing, or by sharing a drinking glass, an eating utensil or a needle, but the disease isn't very contagious. The virus is also found in the mucus of the infected person, so it is also easily spread through coughing or sneeze. It is estimated that 95% of adults in the world have been infected with the Epstein-Barr virus at some point in their lives. The most common age range of people who get mono is between the ages of 15-17. The virus infects B cells (B-lymphocytes), producing a reactive lymphocytosis and the atypical T cells (T-lymphocytes) which give the disease its name.

Symptoms and physical signs

A person can be infected with the virus for weeks or months before any symptoms begin to appear. Symptoms usually begin to appear 4-7 weeks after infection and may resemble strep throat or other bacterial or viral respiratory infections. These first signs of the disease are commonly confused with cold and flu symptoms. The typical symptoms and signs of mononucleosis are: * Fever - this varies from mild to severe, but is seen in nearly all cases. * Enlarged lymph nodes - particularly the posterior cervical lymph nodes, on both sides of the neck. * Sore throat (throat infection) - nearly all patients with EBV-mononucleosis have tonsillitis, usually accompanied by thick exudate. * Fatigue (sometimes extreme fatigue) Some patients may also display: * Enlarged spleen or liver * Abdominal pain * Aching muscles * Headache * Loss of appetite * Jaundice * Sinus infection * Depression * ...   [ Read More ]
