The parents of 7-year-old Sierra Jane Downing thought she had the flu when she felt sick days after camping in southwest Colorado.
It wasn’t until she had a seizure that her father knew something was seriously wrong and rushed her to a hospital in their town of Pagosa Springs. She had a 107-degree fever, and doctors were baffled by the cause.
“I didn’t know what was going on. I just reacted,” Sean Downing said. “I thought she died.”
The Downings eventually learned their daughter was ill with one of the last things they would’ve thought: bubonic plague, a disease that wiped out one-third of Europe in the 14th century but is now exceedingly rare — it hasn’t been confirmed in Colorado since 2006 — and treatable if caught early.
Federal health officials say they are aware of two other confirmed and one probable case of plague in the U.S. so far this year — an average year. The other confirmed cases were in New Mexico and Oregon, and the probable case also was in Oregon. None were fatal.
Plague is generally transmitted to humans through the bites of infected fleas but also can be transmitted by direct contact with infected animals, including rodents, rabbits and pets.
Officials with the Centers for Disease Control and Prevention acknowledged that a series of frightening illnesses linked to insects and pests have been surfacing lately across the country, including mosquito-borne West Nile virus outbreaks in Texas and other states, deadly hantavirus cases linked to Yosemite National Park, and some scattered plague cases.
