The Color Code Alert Level is based on the average of scores assigned for the number of Porter County's weekly cases per 100,000 and our all test seven-day positivity rate. The overall county score will help guide us as we make the best decisions possible to protect our community and limit the spread of COVID-19. The two metrics used to calculate the weekly county status score are described in detail in the graphic below.
Daily, we calculate the scores for the metrics
above. To calculate test positivity rate, we utilize the prior 7-day average for the all tests
positivity rate for Porter County. Please note that this calculation is lagged by 7 days to ensure
complete testing information has been received.
To calculate Porter County’s new weekly cases, we identify all new positive cases that were
reported in the prior 7 days. This number is then divided
by each county’s total county population and multiplied by 100,000.
We then determine the score for each of the two metric above and average them.
The ranges that determine the overall county color are as follows:
