The number of known coronavirus cases in the United States continues to grow. As of Friday evening, at least 291 people with the Covid-19 illness have been treated in 26 states, according to a New York Times database, and at least 15 patients with the virus have died.

The pace of diagnosis has grown rapidly in recent days, with 64 new cases announced Friday. Though most of the country’s first cases were diagnosed in travelers who had recently returned from overseas, the virus is now spreading rapidly within communities on both coasts, including in California, New York and Washington State. And more states were seeing diagnoses: Health officials in Indiana, Kentucky, Minnesota and Oklahoma reported their first coronavirus cases on Friday.

The New York Times has been tracking every case in the United States for more than a month, using information from federal, state and local officials to keep an accurate count. The numbers in this article are being updated several times a day based on the latest information from that database.
New coronavirus cases announced in the U.S. each day

The number of patients treated in the United States remains a small fraction of those with the virus overseas, where thousands of people have died and tens of thousands have been infected.
The West Coast has the most cases.
For weeks, nearly all of the coronavirus cases in the United States could be connected to overseas travel or to close personal contact with someone who had recently returned from a trip.
But now health officials in California, Oregon and Washington State have all reported incidents of the virus turning up in people with no high-risk travel history. (On the East Coast, New York has as well.)
|How Virus Was Contracted||Confirmed Cases|
|Diamond Princess cruise ship||43|
|Cluster connected to a community in New Rochelle, N.Y.||29|
|Nursing facility in Kirkland, Wash.||24|
|Travel in Italy||21|
|Personal contact in U.S.||20|
|Travel in China||15|
|Travel in Egypt||10|
|Grand Princess cruise ship||8|
Combined, California and Washington account for 163 cases. Those patients include a mix of people who contracted the illness locally, traveled in China or were passengers on the Diamond Princess cruise ship, which docked in Japan after an outbreak on board.
But many U.S. patients — and more every day — were diagnosed without any history of overseas travel, signaling that the illness was circulating within the United States and that people were being exposed in schools, offices and medical facilities.
Patients have been treated in 26 states, and others expect cases soon.
Several states, including Tennessee and New Jersey, reported their first cases of coronavirus this week. Others were bracing for what was increasingly seen as an inevitable spread across the country.
In Hawaii, the governor issued an emergency proclamation before the state had a single coronavirus diagnosis. In Michigan, public health workers raced to increase their coronavirus testing capacity. And in Ohio, which as of Thursday evening had not had a case, the state health director issued an order barring spectators from a sports festival this week in Columbus.
“The mayor, our public health officials and I are gravely concerned that the event as organized poses a unique and unacceptable risk for the spread of Covid-19 for guests and the community,” the state’s governor, Mike DeWine, said in a statement.
Many overseas travelers continue to be diagnosed.
Though more and more unexplained cases have been identified, dozens of people with coronavirus in the United States recently spent time in a country with a larger outbreak.
Several Texans who traveled together to Egypt tested positive for coronavirus this week after returning to the Houston area. The first case in Oklahoma, announced Friday, was linked to a trip to Italy. And in Colorado, a patient who had spent time in Italy apparently contracted the virus after being exposed to a person with the virus on his flight back to the United States.
In Washington State, 14 people have died.
The first coronavirus deaths in the United States were reported over the weekend in King County, Wash., which includes Seattle.
The first fatality, announced Saturday, was a man in his 50s with underlying health conditions. The second, announced Sunday, was a man in his 70s who was a resident of the nursing home in Kirkland, Wash., where several cases have been identified.
On Monday, officials in Washington announced that four more people, including three nursing home residents, had died from the coronavirus. Additional deaths were announced each day this week. Other residents of that facility were hospitalized in critical condition.
The country’s first coronavirus death outside Washington was reported on Wednesday in Placer County, Calif., in an older person who had been infected on a recent cruise from San Francisco to Mexico.
Dozens of U.S. patients were on the Diamond Princess cruise ship.
Forty-three Americans who spent time aboard the ship, where the virus spread among passengers and crew members, were evacuated and treated in the United States.
Those patients, who were flown out of Japan on two U.S. government flights, have received care at hospitals in California, Nebraska, Texas, Utah and Washington State.
A specialized unit at Nebraska Medicine in Omaha treated 13 coronavirus patients from the ship. A handful had returned home by Thursday. But others remained hospitalized as tests continued to show the virus in their bodies.
“One of the things, when we talked about what we don’t know yet, is how long does this hang on,” said Shelly Schwedhelm, Nebraska Medicine’s executive director of emergency management and biopreparedness.
