Infectious Disease Data Hub

This dashboard updates every Wednesday by 3pm. 

Each graph includes data through Saturday of the most recently reported week. These weeks follow the reporting schedule used by the U.S. Centers for Disease Control and Prevention (U.S. CDC) in the Morbidity and Mortality Weekly Report (MMWR).

The dashboard includes people who list Maine as their state of residence. This includes Maine residents who are living somewhere else or get tested in another state. County data reflect where a person lives, not where they got a test.

All data are preliminary and subject to change. This means numbers may change as more information becomes available. This includes when Maine CDC completes investigations or when providers submit reports. 

Privacy and Data Suppression

Maine CDC may suppress certain values to protect confidentiality of individuals represented in this data. Maine CDC makes these decisions according to Maine CDC's Privacy Policy. Maine CDC will always show total county case counts. If the number of cases falls below 3 in any element, Maine CDC may suppress certain values. This may include demographics, age, race, or other categories. If the viewer can combine data points to infer protected information, Maine CDC may suppress those values. 

How to Use This Dashboard

Use the filters located along the top of the dashboard to select the year, condition, or county of interest. You may also filter by county by clicking on the map. You can drill down by month in the Month Drill Down below the filter menu. The blue bar shows the case count while the contrasting orange line in the graph overlay shows the 5-year weekly case median. You can access data from 2016 to present. Downloads are available for the current view in the Export Menu in both PDF and PNG format.

Data Interpretation Considerations

  1. Case counts represent reported confirmed and probable cases. Each condition has a surveillance definition that determines case status.
  2. Changes in testing, case definitions, or reporting requirements may influence trends over time.
  3. Interpret comparisons across counties and demographic groups within the context of Maine. Consider Maine's county population and demographic sizes.
  4. Some conditions became notifiable within the preceding 5 years. For these, the 5-year median only includes data for years when the condition was reportable.
