BACKGROUND
Systematic investigations assessing the clinical impact of human parechovirus (HPeV) disease are sparse. Noninvasive stool samples may be useful for targeted hospital-based surveillance.
METHODS
In the context of a quality management program, all hospitalized children fulfilling predefined case criteria for central nervous system (CNS) infection/inflammation underwent standardized neurologic examinations. Stool samples were collected for HPeV and enterovirus (EV) polymerase chain reaction and molecular typing at the National Reference Center.
RESULTS
From October 2010 to December 2012, stool samples of 284 patients with suspected CNS infection/inflammation were tested yielding 12 (4.2%) HPeV+ samples and 43 (15.1%) EV+ samples. HPeV-positive samples included HPeV-1, HPeV-3 and HPeV-6. No additional pathogens were identified in routine care. HPeV-positive patients were significantly younger (P < 0.001) and more likely to present with seizures (P = 0.001) and rash (P < 0.0001) when compared with HPeV-negative patients.
CONCLUSIONS
In hospitalized children younger than 4 years presenting with suspected CNS infection/inflammation, seizures and/or rash, HPeV should be considered in the differential diagnosis. Large-scale public health surveillance may be indicated.
