  1. Mononucleosis "The Kissing Disease"

  2.  * Cytomegalovirus (CMV) / Epstein-barre virus (EBV).    * Contagious & transmitted by saliva  * EBV is one of the most common human viruses in the world  * Often founded in between the ages of 15 and 17  * Illness occurs in 2 out of every 1,000 adolescents What is Mono?

  3. What are the symptoms? *Develops between 4 and 6 weeks    after infection and generally last 2 to 4 weeks * A loss of apetite * A severe sore throat,  fever, and swollen lymph nodes (glands) in the neck area. * fever from 102 F-104 F

  4. Diagnosis * Mono is confirmed by blood tests.  (Mono-spot and heterophil antibody tests) Mono-spot: Clumping of horse red blood cells by mono antibodies presumed to be in a person's serum. * Heterophil: Looks for antibodies (proteins produced by the immune system to counter the virus) that possess the unique ability to cause clumping of red cells taken from sheep's blood. * Blood tests may show an increase in one type of white              blood cell (lymphocyte).  * Detectable until the second or third weeks of the illness.

  5. Complications... Can affect: * Blood - Autoimmune hemolytic anemia (destruction of red blood cells) -Thrombocytopenia (decreases the number of platelets, which assists in blood clotting.) -Granulocytoplenia (deficiency of white blood cells) *Spleen -Ruptures during the second or third week of illness * Nervous System - Cranial nerve pasies "Bell's palsy" (A temporary form of facial paralysis ) -Seizures -Meningitis

  6. Complications Can effect: *Liver -Hepatitis (inflammation of the liver) *Heart ♥ -Pericarditis (inflammation of the membrane that surrounds the heart) - Myocarditis (inflammation of the middle layer of the heart wall) * Lungs -Swollen tonsils = difficulty breathing.

  7. Mortality *Rate is aound 1 out of 100. *The illness is usually self-limited & passes common viral illnesses resolve. *Treatment is directed toward the relief of symptoms. *Antiviral drugs have no significant effect on mono and may actually prolong the course of the illness. * Occasionally, Strep Throat occurs in conjunction with mono and is best treated with penicillin, erythromycin and ampicillin.

  8. Prevalence  In this the term prevalence refers to the estimated population of people who are infected by mononucleosis each year. * In 2002, it was found that about 95 percent of adults of the age group 35-40 years had been infected by mononucleosis in the United States. * When Epstein-Barr Virus (EBV) infection occurs during teenage, in 35 to 50 percent cases it causes infectious mononucleosis. * In 2005, Epstein-Barr Virus (EBV) infects more than 98% of the world's population. * The Epstein-Barr Virus (EBV) causes infectious mononucleosis in 90% of the cases.
