Summary
Acute flaccid paralysis in a child was caused by Echovirus 7, not poliovirus. This case highlights the importance of virological confirmation for diagnosing paralysis during polio eradication efforts.
Area of Science:
- Virology
- Infectious Diseases
- Neurology
Background:
- Poliomyelitis eradication efforts are nearing completion globally.
- Non-polio enteroviruses can cause paralysis mimicking poliomyelitis.
- Accurate etiological diagnosis is crucial for disease surveillance and management.
Observation:
- A 10-year-old boy presented with acute flaccid paralysis of the lower limbs.
- Stool samples revealed isolation of Echovirus 7.
- A high titer of homologous antibodies against Echovirus 7 was detected.
Findings:
- Echovirus 7 was identified as the causative agent of acute flaccid paralysis in this case.
- The findings underscore the role of non-polio enteroviruses in paralytic illness.
- Virological confirmation is essential for differentiating causes of paralysis.
Implications:
- This case emphasizes the need for continued virological surveillance to detect non-polio enterovirus infections.
- Accurate diagnosis aids in understanding the epidemiology of acute flaccid paralysis.
- Strengthening diagnostic capacity is vital for public health during the final stages of polio eradication.
