The Richland County Health Department says that a woman who tested positive for coronavirus violated her self-isolation order earlier this week. The female in her 40s on Tuesday visited three locations in Olney-Walmart, CVS and Mach One between 6:30 and 7:30 p.m and may have infected anyone in those locations at the time. Health officials say they are asking anyone who visited those establishments during the period to contact the Carle Richland Memorial Hospital Respiratory Evaluation Center at (618) 392-1700 for symptom evaluation and COVID-19 testing.
