A vector-borne disease is one in which the pathogenic microorganism is transmitted from an infected individual to another individual by an arthropod or other agent, sometimes with other animals serving as intermediary hosts. The transmission depends upon the attributes and requirements of at least three different living organisms: the pathologic agent, either a virus, protozoa, bacteria, or helminth (worm); the vector, which are commonly arthropods such as ticks or mosquitoes; and the human host. In addition, intermediary hosts such as domesticated and/or wild animals often serve as a reservoir for the pathogen until susceptible human populations are exposed.
Nearly half of the world's population is infected by vector-borne diseases, resulting in high morbidity and mortality. The distribution of the incidence of vector-borne diseases is grossly disproportionate, with the overwhelming impact in developing countries located in tropical and subtropical areas. The Summary of Key Vector-borne Diseases provides a brief description of the manifestation, causative agent, vector species, host, prevalence, population at risk, present geographic distribution, and possible change in distribution due to climate change of key vector-borne diseases (CIESIN 1994).
a vector is an animal that carries diseases an animal that are vectors are rats
a tick is a vector for diseases such as lyme disease, so it can trasmit diseases from animals (deer) to humans in this case.
A vector is something that carries. Some female mosquitos carry diseases.
Bacteria are not vectors that carry viral diseases.
Infectious diseases spread either by person to person contact, or indirectly by a vector or a fomite.
A vector-borne illness is an illness carried and actively transmitted by an organism, usually an insect, such as a flea or mosquito
infectious and vector diseases and natural causes.
Lyme from ticks, West Nile from mosquitoes.
They are a nuisance pest only, not a known vector.
because the can kill plants by sucking the sap and vector plant viruses and diseases
Make sure you get lots of Vitamin B and regularly check your urine for faeces.
microbes are infectious and act as a vector for spreading diseases of various types....they can spoil food also.
