About 150 to 200 patients of Dr. W. Scott Harrington, who's accused of unsanitary practices, line up outside the Tulsa Health Department North Regional Health and Wellness Center to be screened for hepatitis and the virus that causes AIDS, Saturday, March 30, 2013, in Tulsa, Okla. Oklahoma officials say 7,000 patients of Harrington's in the past six years will receive letters that warn that poor hygiene at Harrington's two clinics created a public health hazard.
