What is Poliomyelitis, paralytic?

Poliomyelitis has afflicted humans for millennia, with evidence found in ancient Egyptian mummies. The disease surged in epidemics in the late 19th and early 20th centuries, causing widespread panic due to its paralytic effects. The development of effective vaccines in the 1950s by Jonas Salk and Albert Sabin revolutionized public health, leading to a dramatic decline in cases and near-eradication efforts globally.

Symptoms

  • Initial flu-like symptoms (may precede paralysis): Fever, fatigue, headache, vomiting, neck stiffness, limb pain.
  • Muscle weakness and severe pain (often preceding paralysis).
  • *Flaccid paralysis*: Sudden onset, often asymmetrical, typically affecting the legs.
  • Loss of deep tendon reflexes in affected limbs.
  • Difficulty breathing or swallowing (in severe cases involving respiratory muscles).

Transmission

Poliomyelitis primarily spreads through the fecal-oral route, meaning the virus is shed in the feces of an infected person and then ingested by another. This can occur through contaminated food or water, or direct contact with feces from an infected person. Less commonly, it can spread via the oral-oral route (e.g., through droplets from a cough or sneeze).

Contagious Period: Varies by disease

Prevention

  • *Poliovirus vaccination*: Oral Polio Vaccine (OPV) or Inactivated Polio Vaccine (IPV) are highly effective at preventing the disease.
  • Ensure full vaccination series for infants and children as per national immunization schedules.
  • Maintain good hand hygiene, especially after using the toilet and before eating.
  • Avoid contact with individuals who are sick, particularly in endemic areas.
