The first pneumonic plague death in Arizona's Coconino County in almost two decades highlights the rare but deadly respiratory disease transmitted mainly by infected fleas.

The disease can be transmitted to humans from animals via flea bites or through direct human contact with an infected animal, which can include pet dogs and cats.

The bacterium can also be transmitted to humans from flea bites or bites from infected animals. This is the first recorded death from pneumonic plague in Coconino County since 2007.

Bravecto Quantum, a breakthrough, long-acting flea and tick treatment and preventative for dogs, will be available soon.
