Nymphal ticks primarily feed on small animals and humans during the spring and early summer, while adult ticks are most active during the winter and seek out hosts from late fall to spring. [ 5 ] In order for a human to be infected by the bacterium, the tick carrying it must be attached for approximately 36 to 48 hours.

Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates.

In ticks, Anaplasma spp. can be transmitted transstadially, and the ticks become infected by feeding off infected animals, allowing for transmission to un-infected animals. [13] Debate exists among scientists regarding the ability for transovarial transmission of Anaplasma spp. in ticks.
Lyme disease is spread to humans through the bite of infected ticks.The tick population is affected by weather and climate.Many factors determine tick population densities as well as diseased population densities of ticks so that no single factor can determine likelihood of exposure to tick-borne disease.
