Wednesday, April 7. San Diego County Chair Nathan Fletcher confirmed the county's move into the orange tier, effective Wednesday. “San Diego is officially moving into the 'orange tier,' yet another significant step in our recovery from COVID-19," Fletcher said in a prepared statement released to the media. "The vaccine has given us a path to save lives, restore our economy, send our kids back to school and get our way of life back. The combination of a low case rate plus the state hitting vaccine milestones allows us to continue moving forward." San Diego County public health officials will share local COVID-19 updates at a news briefing at 1 p.m. Wednesday. NBC 7 will carry that live here.
