Poliomyelitis in Children: Comprehensive Nursing Notes

1. Introduction to Poliomyelitis

Poliomyelitis (polio) is a highly infectious viral disease caused by the poliovirus that primarily affects children under 5 years of age. It is a communicable disease that invades the nervous system and can cause permanent paralysis within hours. The term “poliomyelitis” is derived from the Greek words “polio” (gray) and “myelon” (spinal cord), reflecting the virus’s affinity for the gray matter of the spinal cord.

Key Facts About Polio

  • Caused by poliovirus (serotypes 1, 2, and 3)
  • Transmitted primarily through the fecal-oral route
  • Mainly affects children under 5 years of age
  • Can cause irreversible paralysis in 1 of every 200 infections
  • No cure exists, but it can be prevented through vaccination
  • Polio cases have decreased by over 99% since 1988 due to global eradication efforts

2. Epidemiology

Polio once was a disease feared worldwide, but since the Global Polio Eradication Initiative was launched in 1988, polio cases have decreased by over 99%. Today, wild poliovirus continues to circulate only in a few countries, though vaccine-derived poliovirus can emerge in areas with low vaccination coverage.

Epidemiological Patterns

  • Age Distribution: Primarily affects children under 5 years old, though anyone unvaccinated can be infected
  • Geographical Distribution: Wild poliovirus is currently endemic in Afghanistan and Pakistan
  • Seasonal Variation: Historically more common in summer and fall in temperate climates
  • Risk Factors: Lack of vaccination, poor sanitation, and immunodeficiency disorders

Alert for Nurses

While polio has been eliminated in most countries, nurses should remain vigilant for cases, especially in children with travel history to endemic regions or in communities with low vaccination coverage.

3. Pathophysiology

Understanding the pathophysiology of polio is crucial for effective nursing management of affected children. Poliovirus is an enterovirus with three serotypes (1, 2, and 3) that enters the body and replicates, eventually reaching the central nervous system where it causes damage.

Pathophysiological Pathway

  1. Entry and Initial Replication: Poliovirus enters through the mouth and initially replicates in the oropharynx and gastrointestinal tract
  2. Primary Viremia: Virus spreads to regional lymph nodes and enters the bloodstream
  3. Secondary Viremia: Further replication in reticuloendothelial tissues leads to a secondary viremia
  4. CNS Invasion: The virus crosses the blood-brain barrier and invades the central nervous system
  5. Motor Neuron Destruction: Virus specifically targets and destroys motor neurons in the anterior horn of the spinal cord and brain stem
  6. Paralysis: Destruction of motor neurons leads to weakness and acute flaccid paralysis

POLIO Pathophysiology Mnemonic

Remember the pathophysiological progression with:

P – Portal entry (fecal-oral route)
O – Oropharyngeal & GI replication
L – Lymphatic spread to bloodstream
I – Invasion of CNS
O – Obliteration of motor neurons

Cellular Impact:

At the cellular level, poliovirus attaches to the CD155 receptor (PVR) on motor neurons. Once inside, the virus replicates and causes cell lysis, leading to inflammation and ultimately, loss of function in affected neurons. This selective targeting of motor neurons explains the characteristic motor symptoms without sensory involvement.

4. Clinical Manifestations

Polio infections can manifest in various ways, ranging from asymptomatic infection to severe paralytic disease. Understanding the spectrum of clinical presentations is essential for early recognition and intervention.

Clinical Form Frequency Characteristics Nursing Considerations
Asymptomatic 72% No clinical symptoms but can transmit the virus Important for epidemiological surveillance and contact tracing
Abortive Poliomyelitis 24% Mild illness with fever, sore throat, malaise, headache, and vomiting Often misdiagnosed as common viral infection; observe for progression
Non-paralytic Poliomyelitis 1-5% Aseptic meningitis with headache, neck stiffness, and back pain Monitor for signs of progression to paralytic form
Paralytic Poliomyelitis 0.1-1% Acute flaccid paralysis, often asymmetrical, affecting limbs Requires intensive nursing care and long-term rehabilitation

4.1 Stages of Polio

Stage 1: Prodromal Phase

  • Lasts 2-3 days
  • Fever, malaise, headache
  • Sore throat, vomiting
  • Similar to other viral infections

Stage 2: Meningeal Phase

  • Develops in some patients
  • Neck stiffness and pain
  • Back pain and spasms
  • Positive Kernig’s and Brudzinski’s signs

Stage 3: Paralytic Phase

  • Develops 1-10 days after prodrome
  • Asymmetric flaccid paralysis
  • Absent deep tendon reflexes
  • Preservation of sensory function

Stage 4: Recovery Phase

  • Begins 2-3 weeks after onset
  • Recovery of some muscle function
  • May continue for 6-24 months
  • Residual paralysis may remain
