Here are some of the most significant recent developments as the region responds to the pandemic of the novel coronavirus, which causes the disease covid-19:
• Deborah Birx, lead coordinator of the White House coronavirus task force, said Friday that Maryland, Virginia and the District lead the country in the percentage of positive test results for the virus and — despite their quarantine measures — have not seen the decline in infections witnessed in other states.
• For the first time in its 50-year history, Wolf Trap is canceling its summer concerts and children’s theater program because of the coronavirus.
• The District, Maryland and Virginia reported an additional 91 coronavirus-related deaths on Friday. Virginia reported 37 deaths, the highest number in 10 days.
• Some parts of Shenandoah National Park in Virginia are reopening in phases starting Saturday morning, officials said. But other areas in the park, including Old Rag Mountain and Whiteoak, and picnic areas remain closed.
• Mayor Muriel E. Bowser (D) laid out plans for a drastically different summer. The city’s Summer Youth Employment Program will be an almost entirely virtual program this year, with teenagers and young adults working remote jobs — like tech support or teaching children to read — and practicing job skills through more than 200 hours of remote training offered through the D.C. Department of Employment Services.
