- 3. saliva
- 4. 2-5 days
- 5. -Sore throat, swollen lymph nodes, difficult swallowing, fever
- -Enlarged parotid glands
- -Pain when chewing and/or swallowing
- -Lasts 1-2 weeks

8. Prevention
- 1. Poliomyelitis
- 2. Picornavirus

- 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

Rabies
1. Causes
2. Caused by
3. Transmission
4. Incubation period
5. Symptoms/Duration
6. Complications
7. Treatment
8. Prevention
- 1. Rabies
- 2. Rhabdovirus; "bullet" shaped virus, Will cross species
- 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
- 7. antirabies ABY must be given before symptoms appear
- 8. vaccine for high risk individuals

8. Prevention
- 1. Hepatitis - inflammation of the liver, Many
- causes of hepatitis (viral, bacterial, chemicals, trauma)
- 2. Hepatitis A Virus (HAV)
- 3. Saliva, Food (shellfish) or water contaminated with human waste infected with HAV
- 4. 15-50 days
- 5. Nausea, vomiting, diarrhea (NVD), Hepatomegaly (enlarged liver), abdominal
- pain, fatigue, muscle ache, jaundice, Lasts for 3-6 weeks
- 6. Scarring of liver, fatty liver, Cirrhosis (late stage liver disease)
