At least 942 new coronavirus deaths and 37,293 new cases were reported in the United States on Sept. 22. Over the past week, there have been an average of 41,490 cases per day, an increase of 13 percent from the average two weeks earlier.

As of Wednesday morning, more than 6,917,900 people in the United States have been infected with the coronavirus and at least 200,700 have died, according to a New York Times database.

Case numbers remain persistently high across much of the country, though reports of new cases have dropped considerably since late July, when the country averaged well over 60,000 per day.

States in the Northeast, where infections were highest this spring, have reported relatively low case numbers for months. Some places that suffered the most in early summer, including Arizona, Florida and California, have since seen steep declines. But some of that progress has been offset by rising case numbers on the Great Plains and in some Southern states.

Deaths, though still well below their peak spring levels, averaged around 850 per day in mid September, far more than were reported in early July.

A year that started out normal — with packed sports arenas, busy airports and handshake-heavy political campaigning — quickly became defined by the pandemic.

In late February, there were just a few dozen known cases in the United States, most of them linked to travel. But by summer, the virus had torn through every state, infecting more people than the combined populations of Louisiana and Wyoming. The national death toll exceeded 195,000, more than the population of Mobile, Ala. And after glimmers of progress in the late spring, cases surged to new records in July.

American life has been fundamentally reordered because of the virus. Concerts, parades and high school football games continue to be called off. Countless people have found themselves jobless and struggling to afford housing. Many schools and colleges will hold few or no in-person classes this fall. More than 88,000 cases have been linked to colleges and universities over the course of the pandemic. In K-12 schools, the Times reviewed official figures and conducted a survey of school districts in eight states and has found thousands of cases and extremely inconsistent availability of data across the country.

The New York Times has found that official tallies in the United States and in more than a dozen other countries have undercounted deaths during the coronavirus outbreak because of limited testing availability.

The New York Times is engaged in a comprehensive effort to track information on every coronavirus case in the United States, collecting information from federal, state and local officials around the clock. The numbers in this article are being updated several times a day based on the latest information our journalists are gathering from around the country. The Times has made that data public in hopes of helping researchers and policymakers as they seek to slow the pandemic and prevent future ones.

The Times’s data collection for this page is based on reports from state and local health agencies, a process that is unchanged by the Trump administration's requirement that hospitals bypass the Centers for Disease Control and Prevention and send all patient information to a central database in Washington.

The places hit hardest

The coronavirus has left no state unscathed. But its impact has been wildly uneven.

Officials in California, Florida and Texas, the states with the most known cases, have each identified more than 700,000 cases. In a few less populous states, including Vermont and Maine, there are fewer than 10,000 patients. And in a handful of remote counties, there has been not even one positive test.

The nation’s most populous places have all suffered tremendously. In Cook County, Ill., which includes Chicago, more than 5,000 people have died. In Los Angeles County, Calif., at least 255,000 people have had the virus, more than in most states. And in New York City, about one of every 360 residents has died.

But unlike in the early days of the pandemic, it is not so simple to say that big cities have been hit hardest. On a per capita basis, many of the places with the most cases have been small and mid-sized metros in the Southwest with large Native American or Hispanic populations. In Yuma County, Ariz., along the country’s border with Mexico, about one of every 17 residents is known to have had the virus. In McKinley County, N.M., which includes part of the hard-hit Navajo Nation, one of every 283 residents has died from Covid-19.

Hundreds of thousands of cases traced to clusters

Coronavirus outbreaks have been traced to funerals, fast food restaurants, cruise ships and Navy vessels. But most of the biggest known clusters have been in nursing homes, food processing plants and correctional facilities, all places where people are packed in close quarters with little opportunity for social distancing.

Read more here about some of the country’s less-noticed coronavirus clusters.

Coronavirus cases have been reported in more than 19,000 nursing homes and other long-term care facilities, according to data collected by The New York Times from states, counties, the federal government and facilities themselves. More than 479,000 residents and employees have been infected in those homes, and more than 77,000 have died. That means more than 35 percent of deaths from the virus in the United States have been tied to nursing homes and other long-term care facilities.

“This disease creates the potential for a perfect storm in a long-term care facility — large groups of vulnerable people living together and a highly transmissible virus that may not cause symptoms in those who care for them,” said Dr. Daniel Rusyniak, the chief medical officer for Indiana’s state social services agency.

In American jails and prisons, more than 210,000 people have been infected and at least 1,250 inmates and correctional officers have died. During interviews with dozens of inmates across the country, many said they were frightened and frustrated by what prison officials have acknowledged has been an uneven response to the virus.

“I am very concerned,” said Adamu Chan, an inmate at San Quentin State Prison in California, which has become one of the nation’s largest coronavirus clusters with more than 2,520 infections and 27 deaths. “There’s no way to social distance. We all eat together. We have a communal bathroom. There’s no way to address a public health issue in an overcrowded facility.”

Since March, The Times has sought information on clusters from state and county officials, as well as companies and facility operators. Of the thousands of clusters confirmed by reporters, The Times is publishing a list of groupings of 50 more cases linked to a specific site, workplace or event.

About the data

In data for the United States, The Times uses reports from state, county and regional health departments. Most governments update their data on a daily basis, and report cases and deaths based on an individual’s residence. Not all governments report these the same way. The Times uses the total of confirmed and probable counts when they are available individually or combined. To see whether a state includes probable cases and deaths, visit the individual state pages listed at the bottom of this page. The Times has identified the following reporting anomalies or methodology changes in the data: New Jersey began reporting probable deaths. New York City released deaths from earlier periods but did not specify when they were from. Texas began reporting deaths based on death certificates, causing a one-day increase. Officials in Texas reported thousands of undated, backlogged cases, causing a spike in the state and national data. To see a detailed list of all reporting anomalies, visit the individual state pages listed at the bottom of this page. The U.S. data includes cases and deaths that have been identified by public health officials as confirmed coronavirus patients, and also includes probable coronavirus cases and deaths when governments report them. Confirmed cases and deaths, which are widely considered to be an undercount of the true toll, are counts of individuals whose coronavirus infections were confirmed by a molecular laboratory test. Probable cases and deaths count individuals who meet criteria for other types of testing, symptoms and exposure, as developed by national and local governments. Governments often revise data or report a single-day large increase in cases or deaths from unspecified days without historical revisions, which can cause an irregular pattern in the daily reported figures. The Times is excluding these anomalies from seven-day averages when possible.
