Pneumonic plague infects Colorado patient and pet dog

A rare case of pneumonic plague has been diagnosed in a patient who is hospitalized in Colorado. 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.

State health officials did not say whether the infected patient is a man or woman, but confirmed that the person has been hospitalized. Officials believe the patient and dog may have been exposed in eastern Adams County, northeast of Denver.

Officials are looking for people who may have had contact with the patient so they can be treated with antibiotics.

Four Cases of Life-Threatening Plague Found in Colorado

Three more plague cases were found in Colorado, a week after the first infection of the deadliest form of the disease was reported in the state in a decade.

The man initially reported with pneumonic plague on July 11 is hospitalized. Two of the new cases also had pneumonic plague, while the third had a milder form. All four cases may be linked to the original man’s dog, which died from the illness, state health officials said.

The people newly-found to be infected were treated with antibiotics, recovered, and are no longer contagious. Health officials suspect the dog that died may been exposed to plague-infected fleas from a prairie dog or rabbit, said Jennifer House, a spokeswoman for the Colorado Department of Public Health and Environment department.

“We’ve had quite a number of cases this year,” House said in a telephone interview. “We do believe the outbreak itself to be over.”

Colorado has had 60 cases of all types of plague since 1957, and nine people have died. Twelve cases of plague have occurred in the past decade in the state. The state’s investigation is ongoing, House said.

Western States

There are three main types of plague. Septicemic plague occurs when the bacteria proliferates in the bloodstream. Bubonic plague takes hold underneath the skin. Pneumonic plague, the most serious, can be spread through coughing and sneezing and occurs when the bacteria enters the lungs.

Plague in all of its forms usually infects an average of seven people yearly in the U.S., and is found mostly in the western states of Arizona, New Mexico and Colorado, according to the Centers for Disease Control and Prevention. The disease is transmitted by fleas, which pick up a bacterium called Yersinia pestis in infected animals such as chipmunks, prairie dogs, ground squirrels, mice and other mammals. “While this is not a daily, weekly, or monthly occurrence, it isn’t without precedence,” said Jim Siedlecki, director of public information of Adams County, where the original victim lives, in a telephone interview. “A case of plague where fleas and prairie dogs are involved isn’t earth shattering for Colorado.”
