A recent case of bubonic plague has many wondering about the rare illness that was once known as the "black death."

CNN Health is reporting that a human contracted plague in Oregon likely from their cat. The individual has received treatment and "poses 'little risk' to the community" according to the story.

But it may come as a surprise that the plague has been recorded anywhere, or that there have been almost 500 cases in the United States in the last 50+ years, according to data from the CDC. If the last time you thought about the plague was your high school history class, here's some basic information to get you up to speed as well as some information about how many cases Montana has had in recent history.

What is the Bubonic Plague?

Bubonic plague is one of three types of plague according to the Mayo Clinic, the others being septicemic plague and pneumonic plague. The CDC says that "80% of United States plague cases have been the bubonic form."

What are the Symptoms?

You might confuse the symptoms of plague with other illnesses but for bubonic plague specifically, it comes with swollen lymph nodes. The Mayo Clinic lists other bubonic plague symptoms as:

  • Sudden high fever and chills.
  • Headache.
  • Tiredness.
  • Not feeling well in general.
  • Weakness.
  • Muscle aches.
  • Rarely skin sores.

How Do You Catch the Plague?

The Mayo Clinic explains that plague is common in rural areas because it's transferred to humans in a germ called Yersinia pestis which is often found on rats or other animals, like the cat in the recent case in Oregon.
