A mild winter coupled with warming weather in the Pacific Northwest has
brought a renewed threat of tick paralysis in animals and people.
Tick paralysis is a somewhat uncommon but potentially fatal disease. It can
affect virtually all warm-blooded land animals including humans - usually
children. Paralysis occurs when certain species of ticks inject potent
toxins from their salivary glands into the host.
"All medical professionals, human and animal, know tick paralysis is a
serious, potentially fatal illness," explained Professor Steve Parish, a
veterinarian and former head of the Washington State University Veterinary
College’s Agricultural Animal Service.
"Llamas and alpacas, the New World camelids, seem to be particularly
susceptible to the effects of the toxin and we don't know why," said Parish,
who has consulted on one case of tick paralysis and treated another already
this spring.
Each spring and summer, WSU's veterinary teaching hospital sees or provides
consultation on several cases of tick paralysis in llamas and alpacas in
particular. The cases come from throughout the Northwest.
Untreated, death rates for tick paralysis have been reported as high as 10
percent or more in humans and around seven percent in domestic animals.
Interestingly, medical literature shows that, in most human cases of the
disease, only a single tick was found on the patient.
Tick repellants will help prevent ticks from attaching to animals and people.
WSU veterinarians recommend that ticks are best removed with curved tweezers
, forceps or gloved fingers. The tick should be grasped close to the skin
and pulled with steady but gentle traction to ensure all the mouth parts
come off with the entire tick.
Folklore removal methods such as applying a lighted match or petroleum jelly
to the tick are not effective.
As with any other potentially infectious source, people should always wash
their hands thoroughly with soap and water.
