Abstract
Epstein-Barr virus (EBV) DNA loads in peripheral blood mononuclear cells (PBMCs), plasma, and saliva, as well as infectivity of the virus in saliva, were evaluated in 20 patients for 6 months after the onset of infectious mononucleosis (IM). All patients displayed sustained high EBV DNA loads in the saliva, associated with a persistent infectivity of saliva at day 180. EBV DNA load in PBMCs decreased significantly from day 0 to day 180 (in spite of a viral rebound between day 30 and day 90 in 90% of the patients), and EBV DNA rapidly disappeared from plasma. These data show that patients with IM remain highly infectious during convalescence.
