Despite caseloads dropping across America, around half-dozen senior officials, including members of President Joe Biden's cabinet and lawmakers, have tested positive for coronavirus in recent days.
As Washington emerges from its Covid cocoon, with tourists returning to the US Capitol and officials attending a white-tie party that had been scotched for the past two years, the coronavirus is again stalking the halls of power.
At least a half-dozen senior officials, including members of President Joe Biden's Cabinet and lawmakers, have tested positive for Covid-19 in recent days, even as caseloads drop across the country.
Days after the Gridiron dinner, usually a highlight of the Washington social calendar, Attorney General Merrick Garland, Commerce Secretary Gina Raimondo and Democratic Representatives Adam Schiff and Joaquin Castro tested positive.
Guests at the white-tie event were required to show proof of vaccination, but a "small number" have reported positive tests since then, Gridiron Club President Tom DeFrank said, adding, "We wish them a speedy recovery."
White House staffers, journalists and other officials have also tested positive in recent days, including Justice Department antitrust chief Jonathan Kanter and Democratic Representatives Katherine Clark and Debbie Wasserman Schultz.
Biden, who was not at the event, tested negative for Covid on Monday, his most recent test, the White House said.
Former president Barack Obama visited Biden, 79, at the White House on Tuesday. Obama tested positive in mid-March.
Vice President Kamala Harris was in close contact with her communications director, Jamal Simmons, who tested positive on Wednesday, the White House said. Harris will continue her public schedule.
White House spokeswoman Jen Psaki said on Tuesday that everyone who comes in contact with the president is tested beforehand and meetings are often socially distanced.
A million fatalities
The coronavirus has killed more than a million Americans since February 2020, according to worldometer tracker.
Deaths and hospitalisations have dropped sharply in recent months, but the new BA.2 Omicron variant now accounts for nearly three out of four cases in the country, according to the US Centers for Disease Control and Prevention.
The latest spate of cases illustrates how it is nearly impossible to avoid the virus entirely, though vaccines, treatments and increasing levels of immunity are making it less likely to cause severe illness, said Amesh Adalja, a senior scholar at the Johns Hopkins Center for Health Security.
"Everybody's going to get this," he said. "But I think we've successfully shifted Covid-19 to the mild end of the spectrum."
