II. Epidemiology
- Worldwide: Responsible for 59,000 deaths worldwide per year
- Children under age 15 years account for 40% of cases
- U.S.
- Eight human cases of Rabies per year
- Up to 8000/year in U.S. of documented cases of Rabies in animals
III. Pathophysiology
- Transmitted by bite of infected mammals
- Saliva, brain and other nerve tissue are infectious
- Blood, urine, and stool are not infectious
- Highest risk animals
- Bats
- See Bat Bite
- Responsible for most U.S. cases of Rabies (87% of cases 1980-2015)
- Dogs
- See Dog Bite
- Worldwide, these are main vector for infection
- Responsible for 11 of 31 U.S. human Rabies cases 2003-2016
- Rabies is less common in dogs (70 cases/year in U.S.)
- Cats
- See Cat Bite
- Most common domesticated animal with Rabies in U.S. (257 cases of cats with Rabies in 2012)
- Raccoons
- Skunks
- Foxes
- Coyotes
- Bobcats
- Woodchucks
- Ferrets
- Bats
IV. Symptoms
- Early
- Local radiating Paresthesia from bite site
- Malaise
- Nausea
- Pharyngitis
- Late
- Restlessness
- Hallucinations
- Aerophobia and hydrophobia are pathognomonic
V. Signs
- Early
- Wound Inflammation
- Hyperesthesia at wound site
- Late
- Dysarthria
- Hoarseness
- Aphonia
- Dysphagia for fluids
- Shallow or irregular breathing
- Seizure
- Delirium
- Opisthotonos stimulated by lights or noises
- Hyperactive Deep Tendon Reflexes
- Nuchal Rigidity
- Abnormal Babinski reflex (Up-going toes)
- Terminal signs
- Flaccid Paralysis
- Hospitalization <1 week after symptom onset
- Coma within one week of encephalopathy signs
- Death
VI. Labs
-
Saliva
- Contains virus
- Microscopic exam
- Brain and spinal cord of suspected infected animal
- Live Observation of suspected infected mammal
VII. Management
- See Rabies Prophylaxis
- See Dog Bite
VIII. Prevention
- Rabies Vaccine
- Avoid bat exposure
- Remove bat roosts from home
- Bats trapped within a home living space are more likely to be sick (disabled navigation)
- Pets should be vaccinated against Rabies
- In U.S., of pets causing a bite evaluated in ER, only 45% of dogs and 8% of cats were vaccinated against Rabies
- Test for Rabies in pets who succumb to illness quickly
