Ebstein Barr virus is associated with –
**Core Concept**
The Epstein-Barr virus (EBV) is a type of herpesvirus that primarily infects B lymphocytes, leading to various clinical manifestations, including infectious mononucleosis and its complications. EBV is also associated with several malignancies, such as Burkitt lymphoma and nasopharyngeal carcinoma.
**Why the Correct Answer is Right**
The correct answer is associated with infectious mononucleosis, also known as glandular fever. EBV infection is the primary cause of this condition, which is characterized by fever, sore throat, lymphadenopathy, and hepatosplenomegaly. The virus triggers an immune response, leading to the production of atypical lymphocytes, which are a hallmark of the disease. The EBV-encoded nuclear antigen 1 (EBNA-1) is a key protein that plays a crucial role in the pathogenesis of infectious mononucleosis.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because while EBV is associated with several malignancies, it is not primarily linked to cervical cancer, which is caused by human papillomavirus (HPV).
**Option B:** This option is incorrect because although EBV has been implicated in the development of Hodgkin lymphoma, it is not the primary association.
**Option C:** This option is incorrect because EBV is not directly linked to the development of multiple sclerosis, a chronic autoimmune disease of the central nervous system.
**Clinical Pearl / High-Yield Fact**
Infectious mononucleosis is often referred to as "mono" or "glandular fever," and it is a classic exam question. Remember that EBV is the primary cause of this condition, and it is characterized by fever, sore throat, lymphadenopathy, and hepatosplenomegaly.
**Correct Answer:** D.
