Director of DC Health Dr. LaQuandra Nesbitt says there are three cases of the UK strain and one case of the South African strain.
She also reminded reporters at a press conference on Thursday that not every person is tested for the variants of COVID-19.
Dr. Nesbitt says further details are not known at this time, but encourages residents to continue washing their hands, social distancing and wearing a mask.
