Epidemic myalgia associated with human parechovirus type 3 infection among adults occurs during an outbreak among children: Findings from Yamagata, Japan, in 2011

These findings suggest that HPeV3, circulating among children in the community, infects their household, including parents, a portion of whom may subsequently show symptoms of myalgia. Our observations in 2008 and 2011 strongly suggest that clinical consideration should be given to HPeV3 in children as well as in adults during summer seasons in which an HPeV3 outbreak occurs among the children in the community.
