Probable Cases are the total number of patients who are epidemiologically linked (have had close contact) with a confirmed case, have symptoms meeting clinical criteria of COVID-19, and have no confirmatory laboratory testing performed for COVID-19.
Confirmed Cases Per Day
Bama Tracker tracks the change in cumulative cases from midnight to 11:59pm each day. The change shown above can vary slightly from ADPH. Here is a chart of Confirmed + Probable Cases Per Day
Deaths Reported Per Day
Data above is based on reported date, not the date death occurred. To see deaths by date (not reported date), check this chart
On 7/12/2020 ADPH adjusted how they count hospitalizations. More info here.
Hospitalizations Per Day
Increases to the cumulative total.
Currently Hospitalized. 108 Hospitals reporting recently.
Rt Per Day
is the rate of reproduction of the virus. If Rt
is above 1.0, the virus will spread quickly. When Rt
is below 1.0, the virus will stop spreading exponentially. Data from Rt.live
for Alabama. NOTE: This chart will update each Monday.
Case Growth Per Day
Growth % can vary drastically when the numbers are low and gradually reduce as the cumulative count rises. This chart starts at 6/1 to more clearly show recent changes in growth.
Doubling Time (In Days)
Doubling Time (in Days) is the time it will take for cumulative cases to double in value. The chart above shows the 'Doubling Days' over Time based on 7-day growth. Higher is better.
Rate of Deaths Per Day
Cumulative Deaths / Cumulative Cases Per Day
Percent of Counties With New Cases Per Day
Cumulative %Positive Per Day
Based on the running cumulative Total Cases / Total Tests each day. New test counts fluctuate greatly each day, so these percentages are based on the cumulative counts tracked over time. Example: Today would be 417501 / 2611777 = 15.99%.
7-Day Avg. %Positive Per Day
This is the 7-day avg amount of new cases divided by 7-day avg new tests reported each day. The "Ideal Range" comes from data presented by Johns Hopkins described in detail here
Tests Per Positive
How many tests does it take to find 1 positive case? More testing with fewer positive cases is assumed to be an indication of progress. Idea by @twang0518
14-Day Counts %Positive Per Day
This is the 14-day count of new cases divided by 14-day count of new tests reported each day by ADPH. The "Ideal Range" comes from data presented by Johns Hopkins described in detail here
. Data started on 5/18/2020. On January 7, 2021, ADPH corrected an error in the way 14-day tested counts were being computed. This resulted in a large increase in the number of tests causing the 14-day-based Percent Positive value to fall sharply.
