A miscellaneous group of communicable diseases that may be caused by viruses (encephalitis, hemorrhagic fever), rickettsia (typhus, Rocky Mountain spotted fever, Q fever), bacteria (Lyme disease, relapsing fever), and protozoa (babesiosis). Most tick-borne diseases are zoonoses, and they are transmitted to humans by ticks that primarily infest the animal host. Control measures vary. Some respond to elimination of ticks from animal hosts; others require ecological approaches to deal with the ticks' habitat.
