Prevalence and Neighborhood Geomapping of COVID-19 in an Underserved Chicago Pregnant Population.

 The Chicago area is known to harbor some of the deepest racial and ethnic socioeconomic inequalities in the United States. We studied the prevalence and neighborhood distribution of patients who tested positive for COVID-19 after implementation of universal screening at an academic hospital providing obstetrical services to an underserved Chicago population.  From April 16 to June 16, 2020, a total of 369 patients were screened for COVID-19 at University of Illinois at Chicago with either the Abbott Point-of-Care (POC,  = 266) or reverse transcription polymerase chain reaction test (RT-PCR,  = 101).
