White House Seeks $850 Billion Coronavirus Stimulus: Live Updates

Bus service in Detroit was halted after drivers, fearing for their safety, balked at leaving their garages. In North Carolina’s Outer Banks, some officials said they would establish checkpoints to turn away visitors. And Florida moved to ban beach groups of more than 10, after photos showed packed Gulf Coast beaches this week during Spring Break.

The spread of the coronavirus continued to upend life in America on Tuesday in ways large and small, as the number of confirmed cases continued to climb. That figure surpassed 5,000 as testing, which was initially limited, has expanded, according to a New York Times database that is tracking every identified case in the country. At least 95 people have died.

The popular St. Patrick’s Day parades in New York City and Boston were canceled — as they were in Dublin, where people were encouraged to celebrate the day online using the hashtag #StPatricksDayTogether. Many bars and pubs around the United States were closed before the holiday, shutting them down on what is traditionally one of their busiest days of the year.

In Northern California, residents of seven counties began their new cloistered life under a “shelter in place” order that took effect Tuesday — keeping them home except for essential reasons, including buying food and caring for pets, in some of the nation’s most restrictive measures.

The bus problem in Detroit began Tuesday morning when drivers showed up to their garages but then refused to drive, leaving passengers stranded. The city issued a statement saying that because of a driver shortage, there would be no service at all.

Glenn Tolbert, the president of Amalgamated Transit Union Local 26, which represents the drivers, said that some drivers had reported to work early in the morning and found that the buses weren’t adequately cleaned. The state’s order that restaurants and bars to switch to take-out service, and that hospitals severely restrict visitors, deprived drivers of the places they would go to visit restrooms and wash their hands, he said.

“We just didn’t feel that the city, although they were making an effort, was doing enough to protect us and the public,” Mr. Tolbert said.
