[Clinical presentation of primary cytomegalovirus infection in a non-immunodepressed adult].

In the immunocompromised patients and during foetal life an acute infection due to the cytomegalovirus (CMV) causes great morbidity. In adults without predisposing factors the acute infection with CMV is rarely symptomatic, but can also provoke fever, fatigue, headache and anorexia for weeks. The peripheral blood smear shows big atypical lymphocytes within a relative lymphocytosis. The suspicion of the CMV infection is confirmed by the serological evidence of IgM anti-CMV antibodies. There is no etiological treatment, the evolution is spontaneously favorable most of the time. Establishing the diagnosis is reassuring for the patient and for the physician and avoids unnecessary analyses and treatments. We describe a series of 11 adults without predisposing factors who contracted an acute cytomegalovirus infection.
