Which Of The Following Diseases Is Transmitted By An Insect Vector?

Insects (mosquitoes, lice, fleas, bed bugs) and ticks are able to transmit a number of diseases caused by infectious agents: viruses (chikungunya virus, yellow fever, dengue fever, etc.), bacteria (Lyme disease, plague, etc.), parasites (malaria, sleeping sickness, leishmaniasis, filariasis, etc.).

What are the diseases spread by vectors?

Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding anthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.

What are the 4 major disease vectors?

available. Malaria, lymphatic filariasis, Japanese encephalitis, some haemorrhagic fevers (yellow fever, dengue, dengue haemorrhagic fever) and viral fevers (West Nile). Sleeping sickness. Chagas disease.

What is a insect vector?

An insect that transmits a disease is known as a vector, and the disease is referred to as a vector-borne disease. Parasites transmitted by insects often circulate in the blood of the host, with the parasite residing in and damaging organs or other parts of the body.

What is vector borne diseases with example?

Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding anthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.

What kind of vector is a human body?

The body louse, Pediculus humanus humanus, is a strict human parasite, living and multiplying in clothing.

Is plague a vector borne disease?

Vector-borne infectious diseases, such as malaria, dengue fever, yellow fever, and plague, cause a significant fraction of the global infectious disease burden; indeed, nearly half of the world’s population is infected with at least one type of vector-borne pathogen (CIESIN, 2007; WHO, 2004a).

Is Ebola vector borne?

Additionally, Ebola virus is not known to be transmitted through food. However, in certain parts of the world, Ebola virus may spread through the handling and consumption of wild animal meat or hunted wild animals infected with Ebola. There is no evidence that mosquitoes or other insects can transmit Ebola virus.

Are humans disease vectors?

Vectors are living organisms that can transmit infectious diseases between humans or from animals to humans. Mosquitoes are the best known disease vector.

What is a vector in infectious disease?

In epidemiology, a disease vector is any agent which carries and transmits an infectious pathogen into another living organism; most agents regarded as vectors are organisms, such as intermediate parasites or microbes, but it could be an inanimate medium of infection such as dust particles.

What is the most common vector borne disease?

West Nile disease is the most prevalent U.S. mosquito-borne illness.

What are the most common vectors?

Common vectors include mosquitoes, ticks and various types of flies.

What is the role of insects in vector control?

Vector control is any method to limit or eradicate the mammals, birds, insects or other arthropods (here collectively called “vectors”) which transmit disease pathogens. Several of the “neglected tropical diseases” are spread by such vectors.

Is Mosquito a pest or parasite?

In biological terms, organisms that live on a host and depend on it to survive are parasites. Even though they feed on their host’s blood, mosquitoes do not live on their hosts as do head lice, for example.

What are the four major vectors?

The four major types of vectors are plasmids, viral vectors, cosmids, and artificial chromosomes. Of these, the most commonly used vectors are plasmids.
