Number of new confirmed cases COVID-19 Surveillance Three-day rolling average Declining days of new confirmed cases A declining day occurs when fewer cases/deaths/hospitalizations/patients/tests are reported at the end of a 14 day period compared to the number at the beginning of the period, using a 3-day rolling average. The number of declining days represents the number of days out of the last 14 days that have been lower than their points of comparison 14 days prior. MD iMAP services
Number of new COVID-19 related deaths COVID-19 Surveillance Three-day rolling average Declining days of new COVID-19 related deaths A declining day occurs when fewer cases / deaths / hospitalizations / patients / tests are reported at the end of a 14-day period compared to the number at the beginning of the period, using a 3-day rolling average. The number of declining days represents the number of days out of the last 14 days that have been lower than their points of comparison 14 days prior. MD iMAP services
Number of COVID-19 related hospitalizations COVID-19 Surveillance Three-day rolling average Declining days of COVID-19 related hospitalizations A declining day occurs when fewer cases/deaths/hospitalizations/patients/tests are reported at the end of a 14 day period compared to the number at the beginning of the period, using a 3-day rolling average. The number of declining days represents the number of days out of the last 14 days that have been lower than their points of comparison 14 days prior.

Number of COVID-19 related patients in ICU COVID-19 Surveillance Three-day rolling average Declining days of COVID-19 related patients in ICU A declining day occurs when fewer cases/deaths/hospitalizations/patients/tests are reported at the end of a 14-day period compared to the number at the beginning of the period, using a 3-day rolling average. The number of declining days represents the number of days out of the last 14 days that have been lower than their points of comparison 14 days prior.

Number of patients with COVID-19 related symptoms visiting hospital emergency rooms COVID-19 Surveillance Three-day rolling average Declining days of patients with COVID-19 related symptoms visiting hospital emergency rooms A declining day occurs when fewer cases / deaths / hospitalizations / patients / tests are reported at the end of a 14 day period compared to the number at the beginning of the period, using a 3-day rolling average. The number of declining days represents the number of days out of the last 14 days that have been lower than their points of comparison 14 days prior.

Percentage of all acute care beds in use Hospital Capacity Days of adequate capacity of acute care beds A day of adequate capacity occurs when the 3-day rolling average meets or exceeds the capacity threshold prescribed. A day of adequate capacity occurs when the 3-day rolling average meets or exceeds the capacity threshold prescribed. Maryland Institute for Emergency Medical Services Systems
Percentage of all ICU beds in use Hospital Capacity Less than or equal to 80% utilization Days of adequate capacity of ICU beds A day of adequate capacity occurs when the 3-day rolling average meets or exceeds the capacity threshold prescribed.

Percentage of tests administered in Montgomery County that resulted in a positive case Testing A sustained flattening or decrease Declining days of test positivity A declining day occurs when fewer cases / deaths / hospitalizations / patients / tests are reported at the end of a 14 day period compared to the number at the beginning of the period, using a 3-day rolling average. The number of declining days represents the number of days out of the last 14 days that have been lower than their points of comparison 14 days prior.
