COVID-19 Trends Dashboard

The Trends Dashboard shows how various COVID-19 metrics are changing over time. Select any metric on the left to show the daily and cumulative trends.

The set of dashboards below is designed to provide an overview of the current and past state of COVID-19 in New Hampshire. Information is shown across 6 tabs: Overview, Testing, Trends, Interactive Map, Interactive Equity, and Schools. Click between tabs to learn more about each dashboard. Users can also download raw CSV files of the data behind each visualization by clicking the download icon associated with each chart. Note: additional detailed information on case numbers continues to be available on the original Case Overview dashboard.

Are the University of New Hampshire's COVID-19 testing results integrated in the SONH COVID-19 Dashboards and press announcements?

Testing metrics on these dashboards may not exactly match information provided in the daily press release since UNH COVID-19 negative test result data is not yet fully integrated into the Public Health systems. UNH and DHHS are collaborating on an automated process to integrate testing information. Until this integration is complete, existing dashboards will report positive results from UNH's COVID-19 testing. Information including combined SONH and UNH COVID-19 PCR tests and test positivity rate can be found here: New Hampshire PCR Test Results with All University of New Hampshire Test Included and UNH's COVID-19 Dashboard is available here: https://www.unh.edu/coronavirus.

Why are some data points not shown?

There are several circumstances where specific data cannot be shown on the dashboards. In each case, the reason is explained on the dashboard. New Hampshire's general suppression principles are described below.

  • "Data Suppressed": The dashboards contain extremely detailed and granular information. In some circumstances, data becomes so granular that data is suppressed when numbers are small to protect the privacy of the underlying individuals.
  • "Data Not Reported": In addition to data suppression, certain sub-divisions of the data are simply not reported as a matter of policy (for example, data for towns with populations of less than 100) to further protect the privacy of individuals.
  • "Rate Not Reliable": When calculating rates (for example, the percentage of the population tested) there are circumstances where the data become so small that they are likely to lack statistical significance when making comparisons. Data may be suppressed in these circumstances to avoid misrepresenting population level trends.

Why don't all metrics match exactly between dashboards and between days when the dashboard is viewed?

New Hampshire's goal is to provide accurate and up-to-date information as quickly as possible. This can lead to circumstances where information is available in some contexts, but not others. For example, only partial demographic information may be available for some cases at a particular point in time. However, this type of information is continuously being updated as new information becomes available through ongoing public health case investigation and outreach. Explanations are provided within the dashboards when these circumstances arise. Additionally, data fixes and improvements may lead to certain previously displayed data to be updated with more accurate or complete information.
