5 Must Know Facts For Your Next Test

1. EBV is transmitted through saliva, often referred to as the 'kissing disease'.
2. Primary infection usually results in infectious mononucleosis, characterized by fever, sore throat, and swollen lymph nodes.
3. EBV establishes latent infection in B lymphocytes, which can lead to reactivation under certain conditions.
4. Diagnosis of EBV infection can be confirmed using serological tests for specific antibodies such as VCA-IgM and EBNA.
5. There is no specific antiviral treatment for EBV; management focuses on symptomatic relief.
