(CDC) The Mucor fungus was responsible for infections that sickened 13 patients, including five who died, after a 2011 tornado in Joplin, Mo. Health officials are urging Oklahoma doctors to be on the alert for similar infections after Monday’s twister.
Doctors treating victims hurt badly in Monday’s devastating Moore, Okla., tornado should be alert for a rare but deadly complication of wind-whipped debris: fungal infections like those that killed five people after the Joplin, Mo., twister in 2011.
That’s the word from government experts in fungal infections, who documented 13 serious cases of necrotizing cutaneous mucormycosis — terrible soft tissue infections — after the Joplin tornado, including instances when visible mold started growing from the patients’ wounds.
It’s not yet clear whether any fungal infections are suspected in the victims of this week’s disaster. In Joplin, it took five days for the first infections to show up; within 10 days, 10 patients had been identified.
“In the chaos of everything, it’s very hard,” said Dr. Gary Wells, medical director for the Norman Regional Health System emergency department, who was at the initial triage site during Monday’s storm. “It is something you keep in the back of your mind.”
Early detection and diagnosis are key to treating the infections, which occur when molds usually found in dirt, decaying wood and other matter become airborne during a heavy storm.
“When they are picked up out of their natural environment and injected into the skin, we’re always concerned about infection,” Park said.
The molds can contaminate the wounds that occur after the blunt trauma, fractures and penetrating injuries common in tornadoes. The resulting infections can lead to serious illness and death. “The case fatality rate can be very high — 50 percent,” Park noted.
The Joplin tornado struck at 5:34 p.m. on May 22, 2011, a monster of a storm rated EF-5, with winds exceeding 200 miles per hour on the Enhanced Fujita Scale used to measure tornadoes. More than 1,000 people were hurt and 162 died.
The Moore tornado was upgraded to an EF-5 late Tuesday. At least 24 deaths and 237 injuries have been reported. The injuries are typical of tornadoes: crush injuries, impalements and major cuts, according to NBC’s Dr. Nancy Snyderman, who spoke to trauma officials in Oklahoma.
Doctors and other health workers have been swamped caring for the victims, so it’s not clear what steps they’re taking to detect or treat potential fungal infections.
“I’m not sure that they’ve gotten that far yet,” said Pamela Williams, spokeswoman for the Oklahoma Department of Health.
The need for vigilance is clear, according to a 2012 review of the Joplin infections published in the New England Journal of Medicine. Skin-related Mucormycosis infections have been reported after other natural disasters, including a 1985 volcanic eruption in Colombia and after the 2004 Indian Ocean tsunami.
“The risk of complex wounds with foreign-body contamination during natural disasters is high, and wound management can pose considerable clinical challenge in post-disaster settings, especially when the local health care infrastructure has been damaged,” wrote authors from the CDC.
