Bubonic Plague

Plague is caused by the bacteria Yersinia pestis which affects both humans and animals. Bubonic plague is the most common form of plague. Humans become infected with plague after handling an infected animal or being bit by an infected* flea from an animal.


How can I get sick? 

  • Through the bite of an infected* flea that was on an infected animal such as a rodent. 
  • Infected* rodents often die causing the fleas to seek a different animal to live on. Dogs and cats can also carry infected* fleas.  
  • Contact with fluid or tissue that has the plague bacteria.  

Symptoms in humans:  

  • Fever (when your body gets a little hotter than normal)  

  • Headaches 
  • Chills (feeling of being cold and shivering) 
  • Tiredness 
  • Swollen or painful lymph nodes*
  • Pains in the stomach, arms and legs  

What can I do to stay healthy? 

  • Make your home rodent free by keeping it clean. Do not leave places for them to hide or food for them to eat. 
  • If you see a dead wild animal, please report sick or dead wildlife to Nevada Department of Wildlife by clicking here.   
    • Use insect repellent* to protect you or your family from possible exposure to fleas while camping, hiking, hunting or any other outdoor activities.  


  • Keep fleas off your pets by using flea control products and seeking care from your veterinarian. Regular checkups with your veterinarian will help keep your pets free from fleas.
