Several articles, recent to early 2014, warn that human activities are spreading vector-borne zoonotic diseases. [ a ] Several articles were published in the medical journal The Lancet , and discuss how rapid changes in land use , trade globalization , climate change and "social upheaval" are causing a resurgence in zoonotic disease across the ...
Human-to-human transmission (HHT) is an epidemiologic vector, [1] [2] [3] [4] [5] [6] [7] [8] especially in case the disease is borne by individuals known as ...
Vectors may be mechanical or biological. A mechanical vector picks up an infectious agent on the outside of its body and transmits it in a passive manner. An example of a mechanical vector is a housefly, which lands on cow dung, contaminating its appendages with bacteria from the feces, and then lands on food prior to consumption. The pathogen ...
The terms "intrinsic incubation period" and "extrinsic incubation period" are used in vector-borne diseases. The intrinsic incubation period is the time taken by an organism to complete its development in the definitive host. The extrinsic incubation period is the time taken by an organism to develop in the intermediate host. [citation needed]
Infectious diseases that are sensitive to climate can be grouped into: vector-borne diseases (transmitted via mosquitos, ticks etc.), waterborne diseases (transmitted via viruses or bacteria through water), and food-borne diseases.(spread through pathogens via food) [12]: 1107 Climate change affects the distribution of these diseases due to the ...
A vector is an organism which spreads disease-causing parasites or pathogens from one host to another. Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms. Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms.
Vector-borne diseases, such as malaria, have distinctive characteristics that determine pathogenicity. These include the survival and reproduction rate of the vector, the level of vector activity (i.e. the biting or feeding rate), and the development and reproduction rate of the pathogen within the vector or host.

Babesiosis is a vector-borne illness usually transmitted by Ixodes scapularis ticks. B. microti uses the same tick vector as Lyme disease, and may occur in conjunction with Lyme. [6] The organism can also be transmitted by blood transfusion.
