The County of Sonoma Department of Health Services has issued a Health Advisory concerning multiple reports of participants in a Tough Mudder race at Sonoma Raceway on Aug. 19 and 20 having developed rash with fever, muscle pain, or nausea/vomiting occurring about 24 hours after the event. The Health Advisory is as follows:

“The Tough Mudder race involved extensive skin exposure to mud. Most affected persons have pustular rash, fever, myalgias, and headache. These symptoms could be indicative of a minor illness called Swimmers’ Itch, but they can also indicate a Staph infection or other more serious bacterial infection such as Aeromonas. If you participated in the race and have a rash with fever or other symptoms, please see your medical provider or, if you do not have a medical provider, your local emergency department. You may wish to take this Advisory with you. Incubation period is 12 to 48 hours.”
