How does epstein-virus interact with body to produce symptoms?

Epstein-Barr virus (EBV) primarily infects B cells of the immune system, leading to their activation and proliferation. This infection often triggers an immune response, which includes the release of cytokines that can result in inflammation and various symptoms such as fever, sore throat, and fatigue. In some cases, EBV can lead to more severe conditions like infectious mononucleosis or contribute to the development of certain cancers. The symptoms arise from both the viral replication and the body's immune response to the infection.
