how does rabies spread

Rabies spreads when saliva or certain nervous system tissues from an infected animal get into broken skin or mucous membranes (eyes, mouth, nose), most often through a bite.

Core ways rabies spreads

• Bites from infected animals : This is by far the most common route; the virus in the animal’s saliva is injected through the skin by the teeth.

• Scratches that break the skin: If the animal’s claws are contaminated with saliva and they break the skin, that can also be a route, though it is less common than bites.

• Saliva into existing wounds or mucous membranes: Saliva that gets into an open cut, or directly into the eyes, nose, or mouth, can transmit rabies even without a bite, because the virus only needs access to broken skin or mucosa.

• Tissue or organ transplants: Very rare cases have occurred through transplants from a donor who had rabies, which is why stringent screening is used.

Intact skin blocks the virus; it cannot pass through unbroken skin.

What does not spread rabies

• Casual contact such as touching an animal, petting fur, or being near it, without bites or saliva entering a wound, does not transmit rabies.

• Blood, urine, or feces are not considered routes of rabies transmission; the virus is primarily in saliva and certain nervous system tissues.

• Human-to-human spread through everyday contact, coughing, or sexual contact has not been documented, other than via transplanted organs or tissues.

Animals that usually carry rabies

• In many countries, especially in Asia and Africa, dogs are the main source of human rabies infections.

• In the United States, rabies is most often found in wild animals such as bats, raccoons, skunks, and foxes; dog-to-human transmission is now rare because of vaccination programs.

Why rabies keeps circulating

• Rabies persists because it circulates in wild animal populations, where vaccination and control are difficult and contacts are frequent (bites during fights, mating, or predation).

• The virus usually incubates for weeks to months before causing severe illness, giving infected animals time to move around and bite other animals, which keeps the virus in circulation.

What to do after a possible exposure

• Immediately wash the wound thoroughly with soap and water for at least 15 minutes, then seek urgent medical care for possible post-exposure vaccination and, if needed, rabies immunoglobulin.

• Health professionals assess the type of exposure (bite, scratch, saliva contact), the species and behavior of the animal, and local rabies risk to decide on vaccination and follow-up.
