From The Official Comic Con International Press Release
To protect public health and slow the rate of transmission of COVID-19, the California Department of Public Health announced a recommendation that gatherings and events of more than 250 people should either be postponed or canceled. Comic-Con (organizer of WonderCon) will abide by this recommendation. Therefore WonderCon Anaheim, scheduled for April 10-12, 2020 in Anaheim, California, will be postponed until a later date. We will begin processing refunds in the coming days.
We continue to work closely with officials in San Diego and at this time no decision has been made regarding the rescheduling of Comic-Con slated to take place this summer; July 23-26, 2020. We urge everyone to follow the recommendations set forth by the Centers for Disease Control and Prevention and your local health officials.
