This might sound like the plot of a scary sci-fi thriller - but it's real.
A Colorado man caught the rarest and most fatal form of the plague and it can be spread in the air from coughing and sneezing. Health officials say it is the first confirmed case in the state since 2004. Plague was also confirmed in the family dog, after the dog died unexpectedly.

The plague – the illness that killed millions of people across Europe in the Middle Ages - is a bacterial infection spread by fleas from rodents. Pneumonic plague is caused by the same bacteria as bubonic plague but it attacks the lungs. It can be treated with antibiotics, but sometimes is still deadly. Officials are looking for people who may have had contact with the patient so they can also be treated with antibiotics.
