About this data For total cases and deaths: The map shows the known locations of coronavirus cases by county. Circles are sized by the number of people there who have tested positive or have a probable case of the virus, which may differ from where they contracted the illness. For per capita: Parts of a county with a population density lower than 10 people per square mile are not shaded. For hot spots: The hot spots map shows the share of population with a new reported case over the last week. Parts of a county with a population density lower than 10 people per square mile are not shaded.

About this data Weekly cases per capita shows the share of population with a new reported case for each week. Weeks without a reported case are shaded gray. The table includes new cases and deaths that were reported in the last seven days.

The New York Times is engaged in a comprehensive effort to track details about every reported 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 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.

Daily case and death reports show the severity of the pandemic over time. The picture can be put into further context by considering the number of tests performed and people hospitalized.

Source: Testing and hospitalization data from the Covid Tracking Project.
About this data Currently hospitalized is the number of patients with Covid-19 reported by the state to be in a hospital on that day. Dips and spikes could be due to inconsistent reporting by hospitals. Tests represent the number of individual P.C.R. viral test specimens reported tested that day.

If the previous level of testing was low, and hospitalizations are not increasing, a rise in daily cases could be explained as a result of increased testing. If daily tests have been increased and cases and hospitalizations have fallen or stayed low, that is a sign that the situation is improving or under control. Hospitalizations and deaths usually lag behind new cases, as it takes time for symptoms to develop and worsen.

Because the definitions used for testing and hospitalization data vary between states, it is not always possible to compare that data in one state to the figures reported in another.

Since March, The Times has paid special attention to cases in nursing homes, food processing plants, correctional facilities and now at colleges and universities. Information on cases linked to these places comes from official releases by governments, companies and institutions directly. The Times is publishing lists of groupings of 50 or more cases related to a specific site, workplace, school or event.

Cases connected to Cases Location
+ Nursing homes 1,013 cases at 11 facilities

About the data

In data for New Hampshire, the Times primarily relies on reports from the state. New Hampshire typically releases new data each day. Weekend counts may be lower because fewer sources report to the state. The state reports cases and deaths based on a person’s permanent or usual residence.

The Times has identified the following reporting anomalies or methodology changes in the data:

Oct. 2: New Hampshire began including probable cases identified through antigen testing and also reported a backlog of 22 cases from one laboratory.

The tallies on this page include cases and deaths that have been identified by public health officials as probable coronavirus patients through antigen testing.

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.
