A teen girl in Oregon has been diagnosed with the Bubonic Plague.
She is the 16th case reported in the US this year.
Doctors believe the girl became infected when a flea bit her during a hunting trip.
The illness is treated with antibiotics and the girl is now recovering in a hospital.
The plague is very rare. There were 17 cases of plague reported in the US in 2006, a record for this country.
Wild animals like squirrels and prairie dogs mainly carry the fleas that transit plague.
Dogs and cat can become infected as well.
