African Trypanosomiasis Both of these parasites are transmitted to human hosts by bites of infected tsetse flies (Glossina palpalis for T brucei gambiense and Glossina morsitans for T brucei rhodesiense), which are found only in Africa. In West African trypanosomiasis, the reservoirs of infection for these vectors are exclusively human. East African trypanosomiasis, however, is a zoonotic infection with animal vectors.

Is Chagas disease a concern for the United States? Chagas disease is caused by a parasite that is most likely found in Central or South America. This parasite, called Trypanosoma cruzi, is related to the African trypanosome that is known to cause sleeping sickness. This parasite is spread by reduvid bugs. It is a major health issue in South America. The United States may be affected by this disease because of international travel and immigration. Since 2007, many blood banks in the United States have been screening for Chagas disease.

Taeniasis/cysticercosis 1 Taeniasis is acquired by humans through the ingestion of tapeworm larval cysts (cysticerci) in undercooked pork.  Human tapeworm carriers excrete tapeworm eggs in their faeces and contaminate the environment when they defecate in open areas.

West Nile virus West Nile Virus (WNV) can cause neurological disease and death in people. WNV is commonly found in Africa, Europe, the Middle East, North America and West Asia. WNV is maintained in nature in a cycle involving transmission between birds and mosquitoes. However, approximately 80% of people who are infected will not show any symptoms. 2  West Nile virus is mainly transmitted to people through the bites of infected mosquitoes. 3  The virus can cause severe disease and death in horses. 4  Vaccines are available for use in horses but not yet available for people.

Toxocariasis Toxocariasis is an illness of humans caused by larvae (immature worms) of either the dog roundworm (Toxocara canis), the cat roundworm (Toxocara cati) or the fox (Toxocara canis).oxocara canis and Toxocara cati are perhaps the most ubiquitous gastrointestinal worms (helminths) of domestic dogs and cats and foxes. There are many 'accidental' or paratenic hosts including humans, birds, pigs, rodents, goats, monkeys, and rabbits.

4 Infective Fungi, 3 Nematodes, 2 Burrowing Bugs, and a Host of Other Tropical (Dermatological) Diseases Two burrowing bugs. On rare occasions, a lovely stroll down the beach in Central or South America can lead to tungiasis, an infection with a female sand flea Tunga penetrans. This burrower enlarges with eggs and has lots of little babies—and unfortunately, this happens under the skin, Craft said.

African Trypanosomiasis East African trypanosomiasis is found in parts of Eastern and Central Africa, including Uganda, Kenya, Tanzania, Malawi, Ethiopia, Zaire, Zimbabwe, and Botswana. Areas where infection is spread are largely determined by the location of the infected tsetse fly and wild animal population.

Dracunculiasis Dracunculiasis, also known as Guinea worm disease (GWD), is an infection caused by the parasite Dracunculus medinensis. A parasite is an organism that feeds off of another to survive. GWD is spread by drinking water containing Guinea worm larvae.Larvae are immature forms of the worm.t also causes the Guinea worm to come out of the wound and release a milky white liquid into the water that contains millions of immature larvae. This contaminates the water supply and starts the cycle over again. For several days, the female worm can release more larvae whenever it comes in contact with water.

- Trypanosomiasis, also known as African sleeping sickness, is an infection endemic to sub-Saharan Africa. It is caused by protozoan parasites called trypanosomes, which are spread by the bite of the tsetse fly.There are two subspecies of trypanosomes that infect humans, each causing a different form of the disease.rypanosomiasis (trəpăn´əsōmī´əsis) , infectious disease caused by a protozoan organism, the trypanosome, which exists as a parasite in the blood of a number of vertebrate hosts. The three variations of the disease that predominate in humans are transmitted by an insect vector.

- In addition, contact with infected animals, most commonly rabbits, wild rodents, and cats, is another common route of transmission to humans (1, 6). Tularemia occurs in various animal species. Lagomorphs, rodents, and sheep are most susceptible; infected animals are frequently found dead or moribund.n addition, contact with infected animals, most commonly rabbits, wild rodents, and cats, is another common route of transmission to humans (1, 6).

- Transmission. Y. pestis has the ability to cause disease in rodents, insects and humans. The primary carriers of the pathogen are the Oriental rat flea, Xenopsylla cheopis, and infected rodents. The path of transmission to humans usually involves a flea feeding on an infected rodent and becoming a carrier of infection.ransmission.

- LifeStraw® Guinea Worm is a plastic pipe with a stainless steel mesh that filters out Guinea worm larvae from contaminated water. It has been a vital tool in global efforts, led by The Carter Center, to eradicate Guinea worm disease. There is no vaccination or treatment for Guinea worm, yet much work has been done to prevent it by providing access to safe drinking water and education. The Carter Center has been the leading organization in the fight against Guinea worm. In 1996, Vestergaard began working with The Carter Center when the company created LifeStraw® Guinea Worm. The filter was the first LifeStraw® product and it provided inspiration for the award-winning LifeStraw® point-of-use water filters that followed.

Defeating the little dragon Is the species of Guinea worm that affects humans the same as the one that has been found in dogs? Primarily scientists want to find out if the species of Guinea worm that affects humans is the same as the one that has been found in dogs. Like other parasites that affect both humans and animals, the species is often specific to its host.

- Some countries in Africa, the Pacific Islands, and Asia have reported Zika in the past and may continue to occasionally report new cases. The risk to travelers in these endemic countries is likely much lower than it is in countries with Zika epidemics (see Q&A: Zika Risk in Countries with Endemic Zika).

Dracunculiasis (Guinea Worm Disease) Guinea worm disease is an infection by the Dracunculus mediensis nematode. The disease is known as dracunculiasis.

Humans ingest infested copepods incidentally when drinking contaminated water.racunculiasis is a nematode (parasitic worm) infection caused by the guinea worm, Dracunculus medinensis. It is also known as guinea worm disease (GWD).

Detailed FAQs Chagas disease is caused by the parasite Trypanosoma cruzi, which is transmitted to animals and people by insect vectors that are found only in the Americas (mainly, in rural areas of Latin America where poverty is widespread). Chagas disease (T. cruzi infection) is also referred to as American trypanosomiasis.It is estimated that as many as 8 million people in Mexico, Central America, and South America have Chagas disease, most of whom do not know they are infected.If untreated, infection is lifelong and can be life threatening.hagas disease (T. cruzi infection) is also referred to as American trypanosomiasis.

Deadly Diseases Spread by Raccoons About 6% of Americans have been exposed to the roundworms that cause this disease, with highest rates of infection in the southeastern United States and Puerto Rico. Up to 20% of Dutch people, up to 39% of Czechs, 40% of Brazilians, and 90% of Nepalese carry antibodies formed after exposure to the parasites.
