These states have had the highest growth in newly reported deaths over the last 14 days. Deaths tend to rise a few weeks after a rise in infections, as there is typically a delay between when people are infected, when they die and when deaths are reported. Some deaths reported in the last two weeks may have occurred much earlier because of these delays.
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 Connecticut and Oklahoma. And in the fall, the national death toll exceeded 250,000, more than the population of Richmond, Va.
The table below was recently changed to show the average number of cases per day in the last seven days instead of the total number of cases over the last seven days.

About this data
American life has been fundamentally reordered because of the virus. Concerts, parades and high school basketball games continue to be called off. Countless people have found themselves jobless and struggling to afford housing. Many schools and colleges have held few or no in-person classes this fall. More than 321,000 cases have been linked to colleges and universities over the course of the pandemic. Thousands more cases have been identified in elementary, middle and high schools.

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 places hit hardest
The coronavirus has moved across the country in distinct phases, devastating one region, then another.
The Northeast experienced the worst this spring, as temporary morgues were deployed in New York City. Over the summer, cases spiked across the Sun Belt, prompting many states to tighten restrictions just weeks after reopening. By fall, the virus was filling rural hospitals in the Midwest and West as it devastated communities that had for months avoided the pandemic’s worst.
More than 1 million cases have been identified in California.
The nation’s most populous places have all suffered tremendously. In Cook County, Ill., which includes Chicago, more than 6,100 people have died. In Los Angeles County, Calif., more than 350,000 people have had the virus, more than in most states. And in New York City, about one of every 350 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. In the summer, cities along the United States-Mexico border added cases at the highest rates. For much of the fall, small and mid-sized cities in the Upper Midwest and West added cases at the highest rates. And by November, cities, suburbs and small towns alike were setting records.

Cases at colleges and universities
Some universities have decided to hold most or all classes online, but many others have reopened their campuses, often with extensive procedures and rules governing behavior and testing. In August and September, as the fall term began, college towns saw some of the highest per capita case growth in the country. And by November, as cases surged across the country, tens of thousands more cases emerged at universities.
More than 321,000 cases among students and employees at more than 1,700 institutions have been reported over the course of the pandemic, according to a Times database. At least 80 deaths have been reported, many of them in the spring, and most of them among employees, not students. But at least four students have died in recent weeks after contracting the virus.
Below are the 10 states with the most cases reported on campuses.

Cases in jails and prisons
In American jails and prisons, more than 252,000 people have been infected and at least 1,450 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.
After more than 2,200 prisoners tested positive, a judge told San Quentin to reduce its population.
Sandy Dowell, 51, an inmate at Swannanoa Correctional Center for Women, a prison in North Carolina, said she feared for her life if the virus spreads inside the facility. She has lung disease, asthma and high blood pressure, and said she believed prisons were disregarding the lives of inmates in their handling of Covid-19. “A life is a life, isn't it?” she said. “I mean, isn’t everyone’s life worth something?”

Cases at nursing homes and long-term care facilities
Coronavirus cases have been reported in more than 26,000 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 662,000 residents and employees of those homes have been infected, and more than 94,000 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.

Cases at food production facilities
Early in the pandemic, cases emerged by the hundreds in food processing facilities. The outbreaks disrupted the country’s meat supply and led some of the hardest-hit plants to temporarily close.
In July, the Centers for Disease Control and Prevention reported more than 16,000 infections and 86 deaths tied to meat and poultry processing. But those numbers are almost certainly an undercount. Only 28 states provided data to the C.D.C., and many states and food processing companies have refused to provide case totals. Other large outbreaks have emerged on farms, in fruit or vegetable processing facilities and at plants where pet food is made.

Other significant clusters
The coronavirus has followed Americans wherever they gathered, spreading early this year, on cruise ships and at business conferences. As the country has reopened, new clusters have emerged at churches, restaurants and workplaces. Read more here about some of the country’s less-noticed coronavirus clusters. Because many states do not provide information about where the virus spread, no listing of clusters and local outbreaks will be complete.

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:
June 25: New Jersey began reporting probable deaths, including those from earlier in the pandemic, causing a jump in the number of total deaths.
June 30: New York City released deaths from earlier periods but did not specify when they were from.
July 27: Texas began reporting deaths based on death certificates, causing a one-day increase.
Sept. 21: Officials in Texas reported thousands of undated, backlogged cases, causing a spike in the state and national data.
Nov. 4: Georgia began reporting probable deaths, causing a one-day increase.
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.

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.
