Can infectious diseases be spread by animals?
Scientists estimate that more than 6 out of every 10 known infectious diseases in people can be spread from animals, and 3 out of every 4 new or emerging infectious diseases in people come from animals. Because of this, CDC works 24/7 to protect people from zoonotic diseases in the United States and around the world.
What is the difference between contagious and infectious?
Infectious diseases are caused by microscopic germs (such as bacteria or viruses) that get into the body and cause problems. Some — but not all — infectious diseases spread directly from one person to another. Infectious diseases that spread from person to person are said to be contagious.
How are diseases transmitted from one animal to another?
Animal diseases can be spread by 5 main routes of transmission: direct contact; inhalation of aerosols; ingestion; indirect transfer by fomites, such as equipment, footwear or vehicles; or vector transmission. Direct contact is one of the main methods of disease spread between animals.
Can a disease be transmitted from an animal to a person?
Some infectious diseases can be transmitted from an animal to a person. This can happen when an infected animal bites or scratches you or when you handle animal waste. The Toxoplasma gondii parasite can be found in cat feces.
How are zoonotic diseases spread from animals to humans?
Zoonotic diseases can spread in many ways, such as: 1 working closely with livestock. 2 contact with pets, exhibited animals or wildlife. 3 contact with soil or water contaminated by animals. 4 consumption of unpasteurised dairy products.
How is a disease transmitted from one host to another?
These include mosquitos, fleas, and ticks. The insects become infected when they feed on infected hosts, such as birds, animals, and humans. The disease is then transmitted when the insect bites a new host.
What are the most common sources of animal transmitted diseases?
The bacteria are commonly found in the feces of infected animals and in food products contaminated with the bacteria during processing or preparation. Raw or undercooked chicken is one of the most common sources of human infection. Cat scratch disease is a mild to severe bacterial disease caused by Bartonella henselae.

How is a vector-borne disease transmitted from person to person?
Insect bites (vector-borne disease) Some zoonotic infectious agents are transmitted by insects, especially those that suck blood. These include mosquitos, fleas, and ticks. The insects become infected when they feed on infected hosts, such as birds, animals, and humans. The disease is then transmitted when the insect bites a new host.
