The disease caused by the novel coronavirus has killed at least people in the United States since February and has enveloped nearly every part of the country.
Places with highest daily reported cases per capita
7-day rolling average of daily new reported cases per 100,000 residents
As health officials long predicted, autumn brought soaring case counts, strained hospital capacity and increased deaths nationwide, as the virus is not only popping up in new places but also circling back to areas that once appeared to have it contained. Nearly all metrics in most of the country are trending in the wrong direction.
During an April peak, the seven-day-average U.S. death toll hit more than 2,000 per day, but cases were concentrated largely in the Northeast. During a July lull, average deaths sank to a low of 463 per day, although cases surged in the Sun Belt.
In November, however, the country was recording more new cases than ever — well over 100,000 per day — and many states reported record-high caseloads and hospitalizations. The average number of deaths per day again shot past 1,500, despite improvements in treatment that make survival more likely.
Health officials feared holiday gatherings would turbo-charge the spread and tried to discourage them, with mixed results.
New reported cases per day
At least have been reported since Feb. 29.
No data is available in this period for All U.S.
Numbers in this article have fluctuated as testing and reporting criteria have evolved, particularly in areas that were hit early. Three spikes in the deaths chart above reflect large, one-time adjustments: In mid-April, New York City added more than 3,700 deaths. New Jersey added more than 1,800 on June 25. And in September, The Post changed its methodology for reporting deaths in New York and added a one-day increase of more than 2,700 on Sept. 18.
Health officials, including the country’s top infectious disease expert, Anthony S. Fauci, have said the virus has killed more people than official death tolls indicate.
Reported cases per 100,000 residents by county since last week
New York, which was slammed with the new disease in spring and where at least have died, is one of several states experiencing a second or even third wave.
Sun Belt states had serious outbreaks after Memorial Day when people flocked to beaches. By late summer, parts of the Midwest were inundated. In August and September, clusters appeared in newly reopened college campuses, particularly in the Northeast and Midwest. By October, Upper Midwest, Great Plains and Western states that had previously been mostly spared were reporting major outbreaks.
And in November, most states reported record-high case counts and greater demand for hospital beds. Several set records for single-day fatalities.
In the absence of a federal plan, containment strategies vary by state and locality and have often reflected political polarization. The mounting crush of cases this fall, however, has prompted officials of both parties to tighten mask mandates and reimpose restrictions on gatherings to try to squelch the spread.
A majority of states and many retail chains required masks in public places by late July, and public health officials touted them as one of the easiest ways to stop the pandemic. Still, some people in even the hardest-hit areas refuse to wear them, despite evidence that they protect wearers and those around them.
Case and death counts by place
|Place||Total reported cases per 100k||New cases in last 7 days per 100k||Change in daily cases in last 7 days|
People older than 65 and those with obesity and underlying health problems are the mostly likely to die from covid-19, but a large percentage of infections occur in younger, more mobile people. People younger than 40 tend to become less sick but also unknowingly may pass the disease to others around them.
Sparsely populated areas don’t have the huge raw numbers that cities have reported, but some rank among the highest in deaths and cases per capita.
As of Thanksgiving, covid-19 had been documented in every U.S. county except the country’s smallest, Kalawao County, Hawaii, which is home to fewer than 100 people and is so remote that it was the site of a leper colony. Areas in Montana, the Dakotas and Idaho had some of the highest per capita caseloads.
People in very rural areas may be more vulnerable to covid-19 than urbanites, according to a Post analysis of CDC data.
Ten counties with highest rates of reported cases

Testing was slow to begin in the United States, and a system has yet to be standardized.
Demand has often overwhelmed testing infrastructure, muddying the ability of officials to get a true picture of the virus’s reach. A CDC study estimated that just 1 in 8 coronavirus cases nationwide were reported through the end of September. More recently, conflicting CDC guidelines about whether people without symptoms should be tested caused confusion and inhibited contact tracing.
Tests reported per 100,000 residents
|State||Tests reported per 100k||New tests reported in last 7 days per 100k||Percent positive in last 7 days|
A sharp increase in hospitalizations in late fall demonstrates that the virus is spreading, not just that more testing is finding more asymptomatic cases. Some hospitals, straining to find beds and health-care workers to handle the crush of patients, are considering unusual measures.
In North Dakota, health-care workers who test positive but have no symptoms can continue working in covid-19 wards. Facilities in some states are limiting routine care and deferring non-emergency surgeries.
Reported covid-19 hospitalizations per 100,000 residents

Not all news is bleak, however.
Vaccines produced by pharmaceutical and biotechnology companies have produced promising results in clinical trials, and one or more could be approved and available to some high-risk people by the end of the year. Fauci told CNN in November that the average American may have access to a vaccine by April.

October 30 Added several notes clarifying which days states are expected to report data.
October 28 Switched to reported case counts from the Kansas Department of Health and Environment which only provides data updates on Mondays, Wednesdays and Fridays. This has also resulted in a one-day spike of reported cases on Oct. 28.
September 18 Switched to using the confirmed death counts for Bronx, Kings, New York, Queen's, and Richmond counties as reported by New York City, while continuing to use the state's reporting for deaths in all other counties. This has resulted in a one-day spike of 2,732 deaths. Read more about how NYC's methodology differs from NY state's. The Post has been using the city's probable death counts since April.
Given the difference in the methodologies between the state and the city, the Post feels that the city's numbers, which are derived both from positive blood tests and from deaths reported by the city's Office of the Chief Medical Examiner, provide a clearer indication of the fatality count than the state's approach, which uses numbers reported by hospitals, nursing homes, and other health care facilities. This means that the city's counting process is more likely to include deaths that occurred outside of care settings.
August 24 Replaced the modeled trend with a more standard 7-day rolling average of new daily cases and deaths.
August 20 Added a module to show the aggregate statistics in the U.S. and each state/territory over the past week.
July 29 Added hospitalization data and other page improvements.
July 2 Replaced the 7-day running average of new cases and deaths with a 14-day modeled trend. Added the week-over-week percentage change to the trends charts, using the modeled trend values. Also added additional columns to the data tables.
June 23 Added charts showing new daily counts in each state, ordered by the percentage increase in cumulative cases over the last week. Changed the default view of the page to confirmed cases per 100k.
June 11 Added an option to view change since last week to the map. The default view of the map is now deaths per 100k in the last seven days.
May 13 Added a line indicating the seven-day rolling average or reported cases and deaths to the national and state by day chart at the top of the page. The deaths total at the top of the page was revised to round the deaths number down to the nearest thousand.
May 6 Included revised data from New York City probable covid-19 deaths that attributes each death to the day it was first reported instead of on April 14.
April 24 The data on the page was revised to include Post-reported numbers. Reported data for New York City is now reported separately by county instead of being aggregated into one New York City total.
April 23 Date when states began reopening added to state charts.
April 21 Charts showing testing data for all U.S. states and territories were added to the page.
April 14 New York City adds nearly 3,700 probable covid-19 deaths to its total.
April 7 Labels showing the date state emergency and stay-at-home orders were declared added to the state charts.
