It is a Vector (epidemiology), vector for several diseases of animals, including humans (Lyme disease, babesiosis, Human granulocytic anaplasmosis, anaplasmosis, Powassan virus, Powassan virus disease, etc.). It is also known to parasitize mice, lizards, migratory birds, etc. especially while the tick is in the larval or nymphal stage.
