[ 8 ] [ 9 ] Tick populations are also affected by changes in the populations of their hosts (e.g. deer, cattle, mice, lizards) and those hosts' predators (e.g. foxes).
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.

Lyme disease, also known as Lyme borreliosis, is a tick-borne disease caused by species of Borrelia bacteria, transmitted by blood-feeding ticks in the genus Ixodes. [4] [9] [10] The most common sign of infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week afterwards. [1]
But, as it has spread into new areas and infected more people, the CDC has struggled to capture the full impact. In 2022, the agency redoubled its disease surveillance efforts, with a special ...
