A health care worker prepares to insert a nasal swab to test Patrice Evans, of Hartford, for COVID-19 at Hartford HealthCare’s mobile testing site at Phillips Health Care in Hartford’s North End Tuesday. Testing was free and available all day to pre-registered patients as well as walk-ins during the day-long event. Hartford HealthCare’s mobile testing aims to reach underserved communities in Hartford. Evans, who has asthma, could not get her doctor to give her a test, so she was happy when she heard about the mobile testing. Cloe Poisson / CTMirror.org
