Three adult cases of intussusceptions, associated with enteroviruses occurring within a 3-week period, are reported. Virological studies include viral RNA detection in stool samples and staining for enterovirus protein by immunoperoxidase staining of the resected intestinal tissues. A new mechanism for intussusception associated with enterovirus is proposed. Tap water was implicated in the outbreak. Better monitoring of drinking-water may prevent other cases of non-polio enterovirus infection.

The trigger or triggers for reactivation of varicella-zoster virus have not been well defined in the medical literature. We investigated the role of enterovirus infections in triggering herpes zoster in five patients and correlated the reactivation with transient CD8 T lymphocyte depletion during the acute enterovirus infection.
