WENATCHEE — Dr. Jason Lake takes over at the end of August as Confluence Health’s chief medical officer, replacing Dr. Stu Freed. Meanwhile the steady drumbeat of COVID-19 marches on. Central Washington Hospital cared for 19 patients on Wednesday who were suffering from the pandemic virus. By Thursday, that number was 18. But Dr. Lake says the surge in infections is exactly what Confluence Health feared when the pandemic began back in March, and they hoped it wouldn’t show until later in the fall.
