Mysterious Illness Strikes Boaters on Colorado River
An unusual illness has recently been affecting individuals rafting down the Colorado River in the Grand Canyon. This mystery ailment has prompted an investigation by the National Park Service due to its troubling symptoms.
The affected boaters, such as Matthew Wappett from Logan, Utah, report experiencing symptoms like fever, joint pain, and fluid accumulation in the lungs. Wappett sought medical attention immediately upon completing his river journey in June, discovering a severe knee infection that has since been treated.
“Ever since June 6, I’ve had fevers, bone joint aches,” Wappett said. “I felt like I’ve had the flu for a month, essentially.” His initial belief was that he was alone in this plight until his daughter found a Facebook post from another boater with similar symptoms.
Steven King, who also rafted the river in June, shared his experience on Facebook. By July 9, he had connected with five other groups who suffered similar illnesses. “Test results have been negative for everything and inconclusive for leptospirosis, so we’re thinking maybe lepto,” King mentioned via Facebook messenger, noting that antibiotics have been effective in recovery.
According to the U.S. Centers for Disease Control and Prevention, leptospirosis can be transmitted to humans through contact with water or soil contaminated by the urine of infected animals. However, King highlighted that not all symptoms were consistent with this diagnosis, leaving some uncertainty.
While boaters compare notes online, the National Park Service Office of Public Health has initiated an official inquiry into the situation. “At this time, the investigation is ongoing, and we are not able to comment on the extent of the illnesses, potential diagnoses, or other details while the investigation is underway,” Joëlle Baird, spokesperson for Grand Canyon National Park, communicated in an email. Updates will be shared with the public when available.
In the meantime, Wappett reflects on his precautions during the trip, questioning if more could have been done. “We were super careful around bats and keeping [a] clean camp, and you know, all the standard things, but when the wind picks up and you’re breathing dust … you can’t avoid exposure to these things,” he remarked.
The CDC advises avoiding swimming or wading in potentially contaminated water, particularly following floods or heavy rain, to prevent leptospirosis.
