PORTLAND — A cat in Prineville has been diagnosed with bubonic plague, the fourth case reported in Oregon among people and animals since January of last year.

Christine Stone of the Oregon Health Authority says the cat has been treated with antibiotics and is recovering.

Stone says two people were diagnosed with the bubonic plague last year, and one dog. All survived.

The bacteria that cause the disease are spread to humans from flea bites.

Stone says untreated cases can be fatal, but early treatment with antibiotics cures the infection.
