Enterovirus 71 (EV-71) caused fatal brainstem encephalomyelitis in children during a 1997 outbreak. This led to sudden cardiopulmonary collapse and death, with postmortem studies revealing extensive brainstem damage.

Area of Science:

  • Neurology
  • Virology
  • Pediatrics

Background:

  • An outbreak of hand-foot-mouth disease occurred in 1997.
  • Enterovirus 71 (EV-71) was identified as the causative agent.

Observation:

  • Four children presented with sudden cardiopulmonary collapse.
  • Neurologic symptoms were minimal despite severe outcomes.
  • All children died within hours of admission despite resuscitation.

Findings:

  • Postmortem examinations revealed EV-71 infection.
  • Extensive damage to the medulla and pons was observed.
  • A direct link between EV-71 and brainstem damage was established.

Implications:

  • EV-71 can cause severe brainstem encephalomyelitis.
