The D.C. area could become the next epicenter of COVID-19 cases, White House officials said.

Deborah Birx, the White House’s coronavirus response coordinator, said at a briefing Saturday that New York, Detroit and Louisiana are the nation’s current centers of the outbreak, but D.C., Colorado and Pennsylvania are becoming emerging hotspots. The number of confirmed COVID-19 cases in the DMV surged to more than 10,000 by Wednesday evening, The Washington Post reported Wednesday.

“We’re watching them because they are starting to go on that upside of the curve,” Birx said at the briefing. “We’re hoping and believing that if people mitigate strongly, the work that they did over the last two weeks will blunt that curve.”

Mayor Muriel Bowser said at a press briefing Monday that she’s expressed her concern about the growing number of cases in the region to White House officials. Bowser said she told President Donald Trump and Birx that she’s worried the District will trail behind other cities, like New York City, with the greatest number of outbreaks.

“I’ve been solidly mentioning in all of my communications with the White House and the federal staff our concern for the District, and their responsibilities in the District, so I hope that message is going through,” she said at the briefing.

D.C. has tallied more than 1,400 confirmed cases as of Wednesday evening, according to data from the D.C. government. Ward 2, where GW is located, has logged the second-lowest number of cases – 134 – among the city’s wards, the data shows.

Ward 3 recorded the lowest number with 104 positive cases, and Ward 7 logged the highest with 186, according to the website.

Bowser declared a state of emergency and a public health emergency last month ahead of a stay-at-home order implemented in late March.
