Tick paralysis is a type of paralysis caused by specific types of attached ticks. Unlike tick-borne diseases caused by infectious organisms, the illness is caused by a neurotoxin produced in the tick's salivary gland. After prolonged attachment, the engorged tick transmits the toxin to its host. The incidence of tick paralysis is unknown.
However, the tick has been associated with several other tickborne diseases in humans. Unfed female Haemaphysalis longicornis, ventral (underside) view, about 2.3 mm long. [4] An unfed female is typically 2.0–2.6 mm long and 1.5–1.8 mm wide, and grows to 9.8 mm long and 8.2 mm wide with engorgement. [5]
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.
In a September 2023 study, researchers identified a protein that appears to play a big part in how some ticks — including the deer tick and the Western blacklegged tick — get infected by the ...
Not all ticks in an infective area are infected with transmittable pathogens, and both attachment of the tick and a long feeding session are necessary for diseases to be transmitted. [73] Consequently, tick bites often do not lead to infection, especially if the ticks are removed within 36 hours. [83]
The primary distinction between soft and hard ticks is the amount of time they stay attached to their host. Soft ticks remain attached on the order of a couple hours and may take multiple blood meals from the same host. Hard ticks on the other hand tend to stay attached for several days to weeks, feeding continuously. [3]
