Atypical lymphocytosis of at least 20 percent or atypical lymphocytosis of at least 10 percent and lymphocytosis of at least 50 percent may signal infectious mononucleosis. These cells are readily identified by their increased size and the presence of active DNA synthesis. The infection is most common in populations with many young adults, such as active-duty military personnel and college students, in whom the annual incidence for infectious mononucleosis ranges from 11 to 48 cases per 1,000 persons.4,5, Infectious mononucleosis is relatively uncommon in adults, accounting for less than 2 percent of all adults presenting with sore throat.6 Family physicians should expect to diagnose one to four patients with infectious mononucleosis per year, depending on the number of adolescents in their practice.3,5 The incidence of infectious mononucleosis shows no consistent seasonal peak.2, EBV is a herpes virus that replicates primarily in -lymphocytes but also may replicate in the epithelial cells of the pharynx and parotid duct.7 The infection is spread primarily by saliva, and the incubation period is four to eight weeks.
