A veterinarians' group has put out guidance on handling pets that may have been infected by Ebola. It says that if an animal tests positive, it should be euthanized.

The American Veterinary Medical Association released the guidelines Wednesday. Work on them started a month ago, after a dog in Spain was euthanized because its owner contracted Ebola and a dog belonging to an infected nurse in Dallas was quarantined and then released.

The guidelines say a pet that may have been infected should be quarantined for 21 days. The animal's handlers should wear protective equipment similar to what's recommended for hospital workers who treat Ebola patients.

Federal health officials must authorize Ebola testing for animals. If an animal does test positive, it should be killed and the body incinerated.
