Epstein Barr virus is believed to be responsible for all of the following conditions, EXCEPT:
G.B syndrome
Transverse myelitis
Thrombocytosis
Lymphocytosis
Ebstein Barr Virus usually causes atypical lymphocytosis with thrombocytopenia and neutropenic. The clinical diagnosis can be made from the characteristic triad of fever, pharyngitis, and lymphadenopathy lasting for 1 to 4 weeks. In a very few carriers of this virus causes the emergence of Burkitt's lymphoma and nasopharyngeal carcinoma. The incubation period ranges from 4 to 6 weeks. An increased total number of lymphocytes, greater than 10% atypical lymphocytes, and a positive reaction to a "mono spot" test are seen. In patients with symptoms compatible with infectious mononucleosis, a positive Paul-Bunnell heterophile antibody test result is diagnostic. This virus is associated with a higher risk of ceain autoimmune diseases, especially dermatomyositis, systemic lupus erythematosus, rheumatoid ahritis, Sjogren's syndrome, GBS, transverse myelitis, and multiple sclerosis.
