Yesterday The Seattle Times reported that a number of publishers—including DC Entertainment and Penguin Random House—as well as some artists pulled out of Emerald City Comic Con, due to "coronavirus concerns." The annual festival draws around 100,000 fans a year from all over the world and is scheduled for March 12–15.
Today, ECCC announced in a press release that it plans to move forward with the festival, but "knowing that no two fans are alike, we have decided to make an exception to our no refunds ticket policy for our fans who are unable or uncomfortable attending Emerald City Comic Con in light of current events." For those that are planning to attend, ECCC says it is "following enhanced cleaning guidelines," asks that anyone attending use "good sense" (if you're sick, or might be, don't go, and wash your damn hands), and says it is "fully prepared to adjust our plans as the situation in and around Seattle develops." You can see the full press release and find a link to the refund form here. And you can find up-to-date information on Washington's outbreak here.
Update March 6: ECCC is now postponed until the summer. See its full statement here.
