Tick Paralysis

Overview:

Paralysis resulting from a tick byte.

Hard- and soft- bodied female ticks are thought to produce a neurotoxin capable of causing paralysis in children. Ticks attach to the skin to feed on blood. It is during this feeding process that the toxin enters the bloodstream. The resulting paralysis is ascending (starting in the lower body and moving up). Affected children develop an unsteady gait (ataxia) followed several days later by lower extremity weakness that gradually moves up to involve the upper limbs. Paralysis may cause loss of respiratory ability and ventilatory assistance may become necessary.
