description •Children with cCMV exhibited persistent long-term CMV urinary excretion.•CMV urinary excretion was significantly longer in children with asymptomatic cCMV.•CMV urinary excretion in children with postnatally acquired CMV began at mean age 1.8 years. Cytomegalovirus (CMV) infection in children is associated with prolonged viral excretion in urine and saliva. This study characterizes CMV urinary excretion in children with congenital (cCMV) and postnatally acquired CMV infection. Children with virologically confirmed cCMV (75 symptomatic and 105 asymptomatic at birth) and 51 children without cCMV were followed through median 11, 18 and 17 years of age, respectively. In children with cCMV, duration of CMV excretion was defined as uninterrupted positive results from initial to last positive culture, and recurrent CMV excretion as ≥1 positive following >1 negative result. CMV urinary excretion in children without cCMV was defined as resulting from postnatally acquired CMV infection. Mean duration of persistent CMV urinary excretion in children with cCMV was 1.9 (maximum 8.7) years for symptomatic and 2.8 (maximum 9.8) years for asymptomatic children (P = 0.011). Mean duration of CMV excretion was not statistically different for 17 symptomatic children treated with ganciclovir (2.4 years) compared with 58 untreated (1.8 years); P = 0.356. Recurrent excretion occurred in 19 (25 %) symptomatic and 21 (20 %) asymptomatic children, at mean age 4.0 and 6.2 years, respectively (P = 0.084). In 16 (31 %) children with postnatally acquired CMV infection, CMV urinary excretion began at mean age 1.8 (range 0.3–7.3) years. Both symptomatic and asymptomatic cCMV were associated with persistent long-term CMV excretion in urine, which was significantly longer in asymptomatic cCMV and not influenced by ganciclovir treatment in symptomatic cCMV. CMV urinary excretion was common in young children without cCMV, suggesting rapid CMV acquisition in childhood.
