Update Aug 26:

After a spike in COVID-19 cases in Delaware once again landed the state on D.C.’s high-risk travel list, a District health source acknowledged the spike was an anomaly but said there are no plans to remove it from the list, according to reporting from WTOP.

Delaware counted a slew of positive tests on a single day, which boosts the seven-day average positivity rate number–a metric that measures how prevalent positive cases are, when compared to the number of tests conducted. When D.C. officials looked at Delaware’s seven-day average  after a large reporting day on Aug. 14, it stood at 11%, but its health department website shows it currently stands at 4.2%. The District’s seven-day average positivity rate among residents is 2.6%. 

The City of Rehoboth’s mayor says being included on D.C.’s high-risk list diverted end-of-summer visitors to the popular coastal state.

Original:

Delaware is back on D.C.’s high-risk list for the final weeks of summer. D.C. re-added the coastal state to its list Monday after removing it earlier in August, meaning visitors to the beaches there must quarantine for 14 days once they return to the District.

Hawaii and South Dakota also joined the list, which will be updated again on Sept. 7. Montana and New Mexico were removed.

The Mayor’s office defines a high-risk state as “where the seven-day moving average of daily new COVID-19 cases is 10 or more per 100,000 persons.” The designation is retroactive and applies to travel within the last 14 days. People under quarantine should monitor their symptoms and get a test if necessary.
