Epstein Barr virus
The Epstein Barr virus has an envelope and double-stranded DNA. It is named after Michael Epstein and Yvonne Barr, 1964. Most humans are infected with it, but don`t show any symptoms. The virus is transmitted via droplet or contact infection (especially saliva), but also transplantations or blood transfusions. It can cause the so-called kissing disease, the Pfeiffer`s disease, also glandular fever, mononucleosis infectiosa.
