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.

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.

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 more cases related to a specific site, workplace, school or event.

Cases connected to Cases Location
+ Food processing facilities 1,501 cases at 4 facilities
+ Colleges and universities 521 cases at 9 schools
+ Prisons 120 cases at 1 prison
+ Other 61 cases at 1 cluster

About the data

In data for South Dakota, the Times primarily relies on reports from the state. South Dakota 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 tallies on this page include probable and confirmed cases and deaths.

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.
