In most cases, primary CMV infection is asymptomatic or produces mild flulike symptoms. Symptoms, when apparent, develop 9-60 days after primary infection. The lymph nodes and spleen may be enlarged, so CMV infection should be included in the differential diagnoses of infections that produce lymphadenopathy. Extreme fatigue may persist after normalization of laboratory values.
