Public Health Chain of Infection
811
Infectious Agent
Rabies is a viral infection that causes inflammation of both the brain and the spinal cord (Siebert).
Reservoir
Suseptible Host
Rabies is a zoonotic disease, meaning that it is a disease that is transmitted to humans via domestic or wild animal reservoirs (Siebert).
Any person/animal around an infected animal is a suseptible host to Rabies. However, children are more likely to get bitten by an animal than adults (CDC).
Some of the more common animals are bats, raccoons, skunks, foxes, and coyotes. However domestic mammals can also get rabies. Cats, cattle, and dogs are the most frequent (CDC).
Breaking the chain
In animals: keep vaccinations up-tp-date, supervise pets, keep indoors, call animal control for stray animals near your pets (CDC).
In humans: 100% curable with vaccines and medical care. However, vaccinating your pet, maintain your exposure to wildlife, call animal control for stray animals, and educate yourself on Rabies
(CDC).
Portal of Entry
Portal of Exit
The rabies virus cannot pass through intact skin, but can only enter skin that is punctured or open (CDC).
The most common way Rabies is spread is through saliva. Not only can rabies be transmitted through bites, but also through licking. If an infected animal licks another animal or human, then it can transmit the disease (Siebert).
Mode of Transmission
