  1. LESSON PLANONPOLIOMYELITIS REPRESENTED BY: PUSHPA KUMARI ROLL NO:29 BASIC B.SC NURSING FOURTH YEAR BATCH (2013-2017)

  2. SPECIFIC OBJECTIVES • Introduction • Definition • Agent and ghost • Types of viruses • Sign and symptoms • Pathophysiology • Diagnosis and prevention • Treatment • Environmental factors • Control measures • Nursing management

  3. INTRODUCTION • Polio, also known as poliomyelitis, is infectious viral disease transmitted through the oral route by ingestion of contaminated water or food or contact with infected sources such as unwashed hands. • The virus is shed in the feces of infected individual for as long as 6weeks. • The disease produces a range of presentations from flu-like symptoms(abortive poliomyelitis)that resolve in 24 to 36 hours(non paralytic)to paralytic poliomyelitis that attacks the motor neurons in the anterior horn of the spinal cord and brainstem.

  4. DEFINITION • Poliomyelitis is a viral disease that can affect nerves and can lead to partial or full paralysis. • Poliomyelitis is the combination of two words ‘polio’ and ‘myelitis’, where-Polio means gray matter and ‘myelitis’ means inflammation of spinal cord. • Poliomyelitis is a disease starts with fever and end with or without flaccid paralysis.

  5. TYPES OF VIRUSES • There are three types of viruses . • TYPE-1 Includes the Brunhilde strains which are pathogenic to man and monkey. • TYPE-2 Includes the Lansing strains which are responsible for diseases in man, monkey, rodents(rats, mice, etc). • TYPE-3 includes(The Leon Strain)are pathogenic only to man and monkeys and differ immunologically from two types.

  6. RESISTANCE • The Poliomyelitis virus survives in sterile water at room temperature for more than 100days;in milk for 90days;in faeces in cold for more than 6months. • It withstands exposure to 0.5-1percent phenol solution and remains viable for several weeks at pH 3.8 – 8.5. • It is rapidly killed on boiling.

  7. AGENT • RNA virus type I, II and III. • Type I is a wild polio virus which causes paralysis. • The virus is found in stools and oropharyngeal secretions of the infected persons.

  8. HOST • The portal of entry is ingestion. • Incubation period is 7 to 14 days. • 6 months to 3years are vulnerable group. • .

  9. SIGNS AND SYMPTOMS • Non – paralytic polio infections develop flu like symptoms that consist of fever, sore throat, headache, malaise and muscle stiffness(neck, back). • Although in some case there is severe muscle aches and spasms, loss of reflexes and flaccid paralysis. • In some individuals, the paralysis may occur very quickly(within a few hours after infection occurs). • Sometimes the paralysis is only on one side of the body. • Post – polio syndrome describes symptoms that develop in patients about 30 to 40 years after an acute polio illness. The Post – polio syndrome symptoms include muscle pain, joint pain and spinal changes such as scoliosis, spondylosis and or secondary nerve root and peripheral nerve compression. • Slowly progressive muscle weakness(any muscles, including the eye muscles and sometimes termed bulbar polio) generalized fatigue and cold intolerance may occur.
