Insights
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.
- This condition can lead to rapid pulmonary edema and death.
- Understanding this link is crucial for managing EV-71 outbreaks.
Abstract:
During an outbreak of hand-foot-mouth disease caused by enterovirus 71 (EV-71) in 1997, 4 children presented with sudden cardiopulmonary collapse and minimal neurologic features. All children received cardiopulmonary resuscitation but died within a few hours of admission. Postmortem studies showed infection by EV-71 with extensive damage to the medulla and pons. We postulate an etiologic link between EV-71 and brainstem encephalomyelitis as the cause of pulmonary edema and death.
