Role of Maternal Antibodies in Infants with Severe Diseases Related to Human Parechovirus Type 31

Human parechovirus type 3 (HPeV3) is an emerging pathogen that causes sepsis and meningoencephalitis in young infants. To test the hypothesis that maternal antibodies can protect this population, we measured neutralizing antibody titers (NATs) to HPeV3 and other genotypes (HPeV1 and HPeV6) in 175 cord blood samples in Japan. The seropositivity rate (≥1:32) for HPeV3 was 61%, similar to that for...

Can We Distinguish between Human Parechovirus Type 3 and Enteroviruses Infection in Neonates and Young Infants Based on their Clinical and Laboratory Findings?

[Human parechovirus-3 infection in a neonate with fever and suspected sepsis].

The human parechovirus (HPeV) are viruses of the recently described Picornaviridae family and are causing several infections in young children. The pathology associated with these viruses is beginning to emerge. The HPeV type 3, has been described particularly in association with sepsis-like febrile syndromes, meningitis and encephalitis in very young infants and neonates. We report the case of...

Human parechovirus type 3 and 4 associated with severe infections in young children.

BACKGROUND The symptoms observed in children with human parechovirus (HPeV) infection vary widely from asymptomatic or mild gastrointestinal infections to more severe central nervous system infections and sepsis-like disease. Many of the disease associations are, however, only suggestive. In this study, we examined the connection between HPeV and acute otitis media, lower respiratory infections...

Human Parechovirus Infection, Denmark

Human parechoviruses (HPeVs) often cause severe illness among young children. National surveillance with routine testing of all cerebrospinal fluid, fecal, and tissue samples was conducted during January 2009-December 2012 in all counties in Denmark (6,817 samples from 4,804 children were screened for HPeV). We detected HPeV RNA in 202 (3.0%) specimens from 149 persons. Young infants were at hi...
