Overview
Signs and symptoms
Tick paralysis results from injection of a toxin from tick salivary glands during a blood meal. The toxin causes symptoms within 2–7 days, beginning with weakness in both legs that progresses to paralysis. The paralysis ascends to the trunk, arms, and head within hours and may lead to respiratory failure and death. The disease can present as acute ataxia without muscle weakness.
Patients may report minor sensory symptoms, such as local numbness, but constitutional signs …
Pathogenesis
