Vector
Vector (Epidemiology)
A vector in epidemiology is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another. Species of mosquito, for example, serve as vectors for the deadly disease malaria.
Types of Vectors[edit | edit source]
Vectors may be mechanical or biological.
Mechanical vectors carry the pathogen on their body from one host to another, not as an infection. For example, a fly can carry pathogens on its hairs to human food.
Biological vectors harbor the pathogen in their body and deliver it to new hosts in an active manner, usually a bite. For example, mosquitoes are vectors for many diseases, including malaria, dengue fever, and Zika virus.
Vector Control[edit | edit source]
Vector control is a significant element of public health pest control programs worldwide. It involves measures taken to interrupt or reduce the spread of disease by managing the vectors that transmit infection.
