The mysterious illness that has forced Korn singer Jonathan Davis to cancel a number of European tour dates has been revealed.

Through a statement on the band’s web site, Davis revealed on Tuesday that he suffers from a blood disorder called immune thrombocytopenic purpura. It means that a low blood-platelet count prohibits blood from clotting properly. For an unknown reason, the body’s immune system then attacks and destroys it’s own platelets.

The rare condition can be brought on by a viral infection or as a reaction to certain medications.

“[The doctor] took some blood tests and when the results came in, they rushed me to the hospital,” said Davis. “It turned out that I have ITP? a blood infection where, because of an allergic reaction I had to some medication, my blood platelets were really low. If I continued to headbang onstage, I could have had a brain hemorrhage and dropped dead on the spot.”

Davis has been released from hospital, and says he expects to make a full recovery within a few weeks.

The band plans to play all dates on the upcoming Family Values tour.
