Data Dashboard

Montgomery County Government is committed to the health and safety of all of our residents and to relying on science and data to make decisions regarding the three phases of reopening of our County.

The primary indicators that the County analyzes are:

  • Case Rate (cases per 100,000 people during the last 7 days)
  • Test Positivity Rate or Percentage (during the last 7 days)
  • Rate of Transmissions

Secondary indicators we evaluate are:

  • Percentage of change in new cases per 100,000 people (during the last 7 days compared with the previous 7 days)
  • Percentage of hospital inpatient beds that are occupied
  • Percentage of intensive care unit beds occupied
  • Percentage of hospital beds occupied by COVID-19 patients

These indicators determine whether activities such as social gathering sizes, restrictions on indoor capacity (restaurants, houses of worships, retail, etc.) and activities that are considered high risk based on contact tracing data will need to be rolled back in order to reduce the risk of transmission.

On August 5, 2021, the public-facing Montgomery County COVID-19 Dashboard methodology for monitoring COVID-19 related metrics was altered to align closer with the Centers for Disease Control and Prevention (CDC) Guidance released on July 27, 2021. Beginning September 3, 2021, information from the  MD Alternate Care Site will be incorporated into the hospital utilization metrics displayed on the COVID-19 Surveillance Dashboard.  View the previous version of the Montgomery County COVID-19 Surveillance Dashboard.

The Center for Disease Control and Prevention's COVID Data Tracker data lags one day behind the information displayed on the Montgomery County COVID-19 Dashboard due to access and availability of data.

Rt (time-varying reproduction number)

The Rt (time varying reproduction number) is the number of secondary infections produced by a single infection. If Rt is greater than 1.0, the epidemic spreads through every susceptible individual in a population. If Rt is less than 1.0, the epidemic spreads, but limps along and disappears before everyone becomes infected.

Rt graph from March 21, 2020, to the present.

CDC Vaccination Information

The U.S. Centers for Disease Control and Prevention (CDC) have compiled vaccine administration data from multiple sources, including jurisdictions, pharmacies, and federal entities. These sources use various reporting methods including immunization information systems, the Vaccine Administration Management System, and direct data submission.

The CDC figures differ from those reported by the State of Maryland, likely due to Montgomery County residents receiving vaccine doses in non-Maryland jurisdictions.

See the CDC COVID Data Tracker for the percentage of fully vaccinated Montgomery County residents according to the CDC.
