Contact tracing of COVID-19 cases give investigators information on who that person was in close contact with and the locations that they visited during their infectious period, which starts two days before and ends 10 days after symptom onset (or date of test if asymptomatic).
These data allow DC Health to help public health authorities understand where transmission of COVID-19 may have occurred. An outbreak is defined as two or more cases of COVID-19 reported at a location within a 14-day period. Please note, in communities with substantial COVID-19 transmission, even if two or more cases are identified at a location, it is possible that the cases are not related. See detailed Data Notes for more information.
