The disease has been reported in natural disasters and catastrophes; 2004 Indian Ocean tsunami and the 2011 Missouri tornado. The first international congress on mucormycosis was held in Chicago in 2010, set up by the Hank Schueuler 41 &amp; 9 Foundation, which was established in 2008 for the research of children with leukaemia and fungal infections. A cluster of infections occurred in the wake of the 2011 Joplin tornado. By July 19, 2011 a total of 18 suspected cases of mucormycosis of the skin had been identified, of which 13 were confirmed. A confirmed case was defined as 1) necrotizing soft-tissue infection requiring antifungal treatment or surgical debridement in a person injured in the tornado, 2) with illness onset on or after May 22 and 3) positive fungal culture or histopathology and genetic sequencing consistent with a mucormycete. No additional cases related to that outbreak were reported after June 17. Ten people required admission to an intensive-care unit, and five died.
