Study Notes

Mononucleosis

Caused by the Epstein-Barr Virus (EBV)
Common human virus, over 90% of people have had it by middle age but it's usually asymptomatic.
Part of the Herpesviruses family (includes HSV 1 & 2, Varicella Zoster, Cytomegalovirus)
Symptoms: high fever, swollen lymph nodes, sore throat, extreme fatigue, head & body aches, swollen liver/spleen, rash
Most commonly affects teenagers and young adults
Highly contagious spread through bodily fluids (saliva, blood, semen), especially saliva
Transmission occurs through kissing, sharing utensils/cups, coughing in close proximity

EBV and Cancer/Autoimmunity

Lymphoma is a cancer originating in the lymphatic system, caused by lymphocytes growing uncontrollably
EBV is associated with several cancers, especially in high-risk groups:
- Burkitt's lymphoma: Linked to EBV and malaria co-infection, particularly in young children in central Africa resulting in B cell cancer.
- Nasopharyngeal carcinoma: Associated with EBV in older Chinese and African men; the exact process of development is unknown.

Mononucleosis

Caused by Epstein-Barr Virus (EBV)
Affects over 90% of humans by middle age (usually asymptomatic)
Part of the Herpesviruses family (includes Herpes Simplex Viruses 1 & 2, Varicella Zoster Virus, Cytomegalovirus)
Symptoms: high fever, swollen lymph nodes, sore throat, extreme fatigue, head and body aches, swollen liver and/or spleen, rash
Most common in teenagers and young adults
Extremely contagious, spread through: saliva (kissing, sharing utensils), blood, semen
Causes a mononucleosis-like infection

EBV and Cancer

Linked to lymphoma (cancer in the lymphatic system), particularly Burkitt's lymphoma
This cancer originates in the lymphatic system due to uncontrollable lymphocyte growth.
Patients with compromised immune systems (co-infections) are at higher risk for developing Burkitt's lymphoma, especially children in central Africa with malaria and EBV.
Also associated with nasopharyngeal carcinoma (cancer in the nasopharynx) in older Chinese and African men.
