Investigation Launched into Illnesses Linked to 'Tough Mudder' Obstacle Course

Participants in a Tough Mudder competition in Sonoma, California, have reported developing skin rashes and fevers after crawling, climbing, and wading through the obstacle course. The County of Sonoma Department of Health Services issued an advisory, stating that multiple people had reported symptoms that could indicate a potentially serious infection caused by Aeromonas bacteria. Symptoms include pus-filled bumps on the skin, fever, muscle aches, and headaches. The department is urging clinicians to obtain cultures from infected patients and report the results. Participants are advised to seek medical attention if they experience a rash with fever or other symptoms.
