On Thursday, the Humboldt County Joint Information Center said a majority of the 110 cases reported so far this week are part of “a single outbreak associated with one or more superspreader events.” Comments made on social media and an anonymous email to the Outpost identified Eureka the Pentecostal Church as the source of the outbreak.
