    • 4. 7-14 days
    • 5. Flu-like symptoms - fever, cough, muscle ache, Diarrhea, Lasts 1-2 weeks
    • 6. -Can spread to blood
    • -Can spread to central nervous system; Damage to myelin protein around nerve cell, Result in paralysis (paralytic polio occurs in 1:1000 polio cases), Paralysis of legs, respiratory muscles, intestines, bladder (Atrophy of muscles, crippling, Breathing difficulty, respiratory failure)
    • 7. physical therapy, iron lung

    • 3. saliva from animal bite
    • 4. 10-180 days
    • 5. -Virus infects wound, spreads into blood, then to central nervous system (brain, spinal cord)
    • -Causes de-myelination of nerve cells
    • -Dumb form (associated with humans); Results in paralysis; respiratory failure, death, Symptoms within 48-96 hours after incubation period
    • -Furious form (associated with animals); Damage to myelin exposes nerves to environmental factors (sound, light, heat, cold, etc.), Increased pain sensation, Aggressive behavior, Eventually becomes dumb form
    • 6. n/a
