-mononucleosis caused by the Epstein-Barr virus -DNA virus
-herpes virus
-latent cycle
-consists of a capsid and envelope
-very common virus
-can lead to many other diseases, e.g- multiple sclerosis, type 1 diabetes,cancer
-EBV infected usually gain adaptive immunity
The Epstein-Barr virus
Symptoms and progression of the disease:
Incubation Period:
-10 days after exposure in children and 30-50 days after exposure in adults.
-takes 3-5 days for more intense symptoms to start showing Symptoms include:
-sore throat,swollen glands in neck armpits groin,nausea,vomiting,enlarged spleen liver,
swollen eyelids,rash,weight loss, and drowsiness.
-less frequent symptoms- mild jaundice(yellowish skin,eyes),neck stiffness,cough,shortness of breath,rapid heart rate.
-may develop hepatitis(inflammation of liver) and pericarditis (inflammation surrounding heart sac)
-6 months to wait for total recovery
-tired feeling is last to go(depression may result)
-mono may come back within a few months but in a lesser case.
-never appears full-blown after a year.
swollen glands in neck
Viral Specificity:
-Infectious
-named for large number of white blood cells in blood stream(mononuclear cells)
-Epstein-Barr virus stays in WBCs for life(latent)
-Sheds virus through saliva
-may develop cancer(Burkitt's lymphoma+cancer in nose and throat)
-viral genes alter growth of infected cells and cause them to possibly become cancerous
-swollen/effects the lymph nodes
-infecting two major cells- outer (epithelial)cells(salirary gland) white blood cells(B-cells) -first develops in salivary glands
-if correct immune response doesn't develop-there is a risk of forming cancer.
Common Methods of Transmission:
-Known as the kissing disease
-Is transmitted through mucus and saliva e.g-sharing food or drinks, utensils, toothbrushes or anything else that has
been near the mouth of an infected person.
Treatment and Prevention:
-No vaccine
-lots of rest, Drink water
-syrups for sore throats
-Acetaminphen(tylenol) for fever/pain
-worse cases-ruptured spleen must be removed in emergency sugery
-Blood tests are done to see if virus is present
-Little to prevent
-Not to kiss or come in close contact anyone who has been diagnosed with disease
Miscellaneous:
-Named after Michael Anthony Epstein and Yvone Barr
- Discoverd in 1961
-90% have been exposed to thie virus but remains latent in your body
