B27.0:
- A common, acute infection usually caused by the epstein-barr virus (herpesvirus 4, human). There is an increase in mononuclear white blood cells and other atypical lymphocytes, generalized lymphadenopathy, splenomegaly, and occasionally hepatomegaly with hepatitis.
- Acute disease characterized by fever and swollen lymph nodes and an abnormal increase of mononuclear leucocytes or monocytes in the bloodstream; not highly contagious; some believe it can be transmitted by kissing.
- 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
- fever
- sore throat
- swollen lymph glands
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.
