One of the key elements in reopening plans, across counties or states, is to increase contact tracing to determine if people infected with COVID-19 may have exposed others to the virus. Maryland employs about 1,400 contact tracers so far, and last week, Mayor Jack Young announced that the new Baltimore Health Corps will hire nearly 300 contact tracers. If you are interested in applying for one of those jobs, go to https://www.baltimorecorps.org/baltimore-health-corps for more information. To tell us more about that program and other aspects of COVID-19 in the city, Dr. Letitia Dzirasa joins Tom. She is the health commissioner of Baltimore City.
