A fan attended their March 28 Key Arena show contagious with the virus after being infected two days prior

Fans who attended Kings of Leon's March 28 concert at Seattle's Key Arena should keep a close watch on their health in the coming days. According to a report from the Washington State Department of Health, a woman attended the concert after becoming contagious with measles.

"Most people in our state are immune to measles, so the public risk is low except for people who are unvaccinated," the report assured. "People who haven’t been vaccinated or aren’t sure if they’re immune should ask a health care professional for advice."

Furthermore, any attendees who develop a fever or rash are encouraged to make an immediate appointment with a health care professional and to call ahead, so as not to infect any persons upon arrival.

The official report also features a complete list of Seattle-area locales the infected woman visited while contagious.

In a similarly bizarre live experience, Kings of Leon were forced to cancel a 2010 St. Louis concert after three songs, due to excessive pigeon droppings.

Their current Mechanical Bull North American tour lasts through April 11. From there, Kings of Leon embark on a world tour that includes stops in the Middle East and Western and Eastern Europe, before returning to the States for Lollapalooza Aug. 3.
