Which parasite is the most common parasitic infection in the United States?
Studies have shown that toxocariasis may be among the most common human parasitic infections in the United States. It is estimated that millions of Americans have been exposed to the Toxocara parasite, although how many persons have become ill from the infection is unknown.
Is Toxocara canis zoonotic?
Toxocariasis is an infection transmitted from animals to humans (zoonosis) caused by the parasitic roundworms commonly found in the intestine of dogs (Toxocara canis) and cats (T. cati).
Are all tapeworms zoonotic?
Tapeworms. Tapeworms are another zoonotic parasite that can be transmitted to humans. Tapeworms have an intermediary host, which means the tapeworm eggs must be eaten by something else, like a flea, where the egg hatches and creates a cyst that, when eaten, forms a tapeworm.
What is emerging zoonotic disease?
Many viral pathogens causing emerging zoonotic infections in humans originated from animals (specifically wildlife) or from products of animal origin. Knowledge of extra-human reservoirs of these pathogens remains essential for understanding the epidemiology and potential control measures of these zoonotic diseases.
Can humans get Toxocara canis?
Anyone can become infected with Toxocara. Young children and owners of dogs or cats have a higher chance of becoming infected. Approximately 5\% of the U.S. population has antibodies to Toxocara. This suggests that tens of millions of Americans may have been exposed to the Toxocara parasite.
Where is Toxocara canis found?
Toxocariasis is a rare infection caused by roundworm parasites. Humans can catch it from handling soil or sand contaminated with infected animal faeces. Roundworm parasites are most commonly found in cats, dogs and foxes, and usually affect young children.
What are some examples of zoonotic diseases?

What diseases are caused by parasites?
Toxoplasmosis (tok-so-plaz-MOE-sis) is a disease that results from infection with the Toxoplasma gondii parasite, one of the world’s most common parasites. Infection usually occurs by eating undercooked contaminated meat, exposure from infected cat feces, or mother-to-child transmission during pregnancy.
How many zoonotic diseases are there?
There are more than 150 known zoonotic diseases. Some of the newer zoonotic diseases including bird flu and swine flu, SARS, HIV, Ebola and Nipah infections have received considerable media coverage.
What are zoonotic viruses?
Zoonosis is a disease that can be transmitted to humans from animals. Transmission occurs when an animal infected with bacteria, viruses, parasites, and fungi comes into contact with humans. Over 200 diseases are currently classified as zoonoses. Common examples include tick-born illnesses such as Lyme disease,…
