---

What causes warts?

Warts in animals are caused by viruses similar to those that cause warts in people.

Papillomas are spread between animals by direct contact.

Where do warts occur?

One type of warts occurs in caribou, moose, wapiti (elk) and deer.

Another type of warts occurs in wolves and dogs.

They are most common in animals younger than 2 years old.

In the NWT and Nunavut, both types occur periodically.

What are the signs of papillomas?

Affected animals are usually in good body condition.

Warts are often found on the head but can occur on other parts of the body.

In caribou and moose, the warts are dark lumps that vary in size from 1 to 15 cm. There may be only one or many and the surface may be rough or smooth.

In wolves and dogs, warts are usually dry, hard, whitish, cauliflower-like lumps on the lips and around the teeth.

How can I protect myself?

You cannot get warts from infected animals.

Can I eat the meat?

Meat from infected animals is suitable for human consumption.
