What diseases are caused 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 are water related vector diseases?
Water-related insect vector diseases include malaria, filariasis, yellow fever, and river blindness. Malaria is the most infamous of these diseases. It is caused by minute parasites, which are spread by mosquitoes. The disease is a well-known killer—particularly among children.
How do vectors affect human health?
Vector-borne diseases. Vector-borne diseases are human illnesses caused by parasites, viruses and bacteria that are transmitted by vectors. The burden of these diseases is highest in tropical and subtropical areas, and they disproportionately affect the poorest populations.
What is the most common vector borne disease in the world?
Dengue is the most common vector-borne viral disease worldwide, and it has been a significant public health threat in the United States since 2009.
What kind of vector is a human body?
The body louse, Pediculus humanus humanus, is a strict human parasite, living and multiplying in clothing.
What is the role of vectors in the transmission of diseases?
Vectors. Vectors are living organisms that can transmit infectious pathogens between humans, or from animals to humans. Often, once a vector becomes infectious, they are capable of transmitting the pathogen for the rest of their life during each subsequent bite/blood meal.
How do vectors make us sick?
Vector-borne diseases are illnesses that are transmitted by vectors, which include mosquitoes, ticks, and fleas. These vectors can carry infective pathogens such as viruses, bacteria , and protozoa , which can be transferred from one host (carrier) to another.
