OMAK — More than two dozen people who attended the Omak Stampede earlier this month have tested positive for COVID-19.

Okanogan County health officials on Wednesday urged anyone who attended the four-day rodeo, which took place Aug. 12-15 in Omak, to watch for COVID-19 symptoms. The caution also applies to people who have been in close contact with someone who attended, the health district said in a news release.

COVID-19 symptoms to watch for include fever, scratchy throat, headache, cough, diarrhea, chills, loss of taste or sense of smell and body aches, nausea or vomiting, or shortness of breath or difficulty breathing, according to the U.S. Centers for Disease Control and Prevention.

If someone who attended the event has symptoms, the health district asks that they get tested and self-quarantine until test results are confirmed as negative.
