Data Notes

2020-09-07: Testing and case reporting appears to have been greatly reduced over Labor Day weekend. The large reduction in new cases around Sept. 9 is likely due to to that, rather than an actual decrease in spread.

2020-09-23: A laboratory reporting error was corrected on 9/18 which caused 357 cases to be dated for 9/17, their reporting date. On 9/23, those cases were moved from 9/17 to their respective sample dates. Versions of this report prior to 9/23 had those cases assigned to 9/17.

2021-06-09: A laboratory reporting error was corrected on 6/9 which caused 390 cases to be dated for 6/2, their reporting date. On 6/9, those cases were moved from 6/2 to their respective sample dates. Versions of this report prior to 6/9 had those cases assigned to 6/2.

* Fully vaccinated persons are those who received a second dose of a Pfizer or Moderna vaccine or a first dose of a Johnson & Johnson vaccine at least two weeks prior to the given date.

*Counts of cases and deaths are based on records reported to and investigated by the Marion County Public Health Department, and may differ from counts from other sources.

**Due to statistical instability, a point estimate would be misleading. Please see the 95% confidence interval.

***Other Race includes both cases and deaths reported as ‘Other Race’ rather than a grouping of specified races. As the race of the individuals in this category is unknown, a matching population denominator cannot be assigned and an accurate rate cannot be calculated.

Current Marion County Case Positivity Rate per 100,000 Residents starting on 2024-01-06 ending on 2024-01-19. Last updated 2024-01-23.

Last Updated 2024-01-23, using data through 2024-01-12.

Marion County schools report cases in staff and students to MCPHD. Every Tuesday, MCPHD will calculate school positivity rates based on the number of staff and student cases in the most recent two-week Saturday through Friday. See below for details on how to calculate a school’s positivity rate.

Every Tuesday, the MCPHD will calculate the school case positivity rates and current risk level of each school, and communicate directly with each school about the results. Due to confidentiality laws and the risk of re-identification, MCPHD will not publicly release information about which schools have COVID-19 cases.

The current Marion County case positivity rate is calculated using the total number of new cases in the past 14 days divided by Marion County’s population times 100,000 and then dividing by 14.

To download a dataset with the 14 day daily average number of cases per 100,000 residents by date in Marion County, click: Download 14 day daily average per 100,000 for Marion County

You can find information about percent positve and average new cases that were previously provided on this page on the Trends tab.

To calculate a school positivity rate:

1. Count cases:
   Add up the number of cases from the most recent two-week Saturday through Friday period. Only include staff and students who are not only attending remotely.

2. Compute the raw rate:
   Divide that by the number of staff plus students who are not only attending remotely. That includes those attending sometimes, as in a hybrid model, as well as those who always attend in person.

3. Standardize the rate:
   Multiple that ratio by 100,000 and divide by 14 to get the daily average number of cases per 100,000 students and staff. That is the school’s case positivity rate.

4. Compute as % of the standardized Marion County rate:
   Divide the school’s case positivity rate by the Marion County positivity rate posted at the top of this page, and multiply the result by 100 to get the school rate as a percent of the Marion County rate.

5. Compare to the risk table:
   Compare that percent to the table above. If that percent is greater than 100, the school community is in the potentially red zone.

Example calculation

Conditions

1. A school has 25 staff and 275 students who attend in-person, for a total of 300 people

2. And that school has had 2 cases among those 300 people in the past 2 weeks

3. And the Marion County case positivity rate is 89 cases daily per 100,000 residents

Calculation

1. Count cases:
   2 cases in the most recent two-week Saturday through Friday period.

2. Compute the raw rate:
   (2 cases / 300 students and staff) = 1 / 150

3. Standardize the rate:
   (1 / 150) x 100,000 / 14 days = daily avg. 47.6 cases / 100,000 students and staff

4. Compute as % of the standardized Marion County rate:
   47.6 / 89 = 53.4%

5. Compare to the risk table:
   53.4% is between 25% and 75%, so that school would be in the yellow zone.

Every Tuesday, MCPHD will calculate school positivity rates using data from the previous 14 days ending on the Friday four days earlier, to allow for reports from schools to be received at MCPHD. So the 14 day period will include cases detected from Saturday two weeks prior through the Friday just before Tuesday when we do the calculation. The report that goes out will have categories of “green”, “yellow”, “potentially orange”, and “potentially red”. School will only become “orange” or “red” if, after contacting the potentially orange or red schools, we identify cases as having in-school links between cases, such as through classrooms or school activities. Since we will not know whether cases have in-school links between cases until after the reports are emailed, the reports will not reflect a school’s final categorization.

The Marion County rate currently used for this calculation is posted on the top of this webpage.

Herd immunity occurs when a significant portion of a population becomes immune to an infectious disease, limiting further disease spread. Vaccination and prior infection with COVID-19 both contribute to developing herd immunity.

The following graphs show for any given day the proportion of Marion County residents who have ever been fully vaccinated or who have ever been infected with COVID-19. It is broken down by age group and by racial and ethnic group. Racial and ethnic groups not listed had too low of a sample to be considered statistically significant.

The following graphs show for any given day the proportion of Marion County residents who have ever been infected with COVID-19 within the last 90 days or who have been fully vaccinated. Thus, a person is considered “immune” from COVID-19 for 90 days following their infection, at which point they then become susceptible again. This is due to evidence suggesting that immunity conferred by prior infection tends to wane after a few months. A person is also considered immune once they have been fully vaccinated. It is broken down by age group and by racial and ethnic group. Racial and ethnic groups not listed had too low of a sample to be considered statistically significant.

Interpreting Rates and Confidence Intervals

Rate per 100,000: Rates are multiplied by a large number - most often 100,000 - to simplify comparisons. A rate per 100,000 will describe the number of events or illnesses that occurred in a population for every 100,000 people.

Confidence Intervals: This dashboard presents 95% confidence intervals with statistics when the information to calculate confidence intervals was available. Confidence intervals are a range in which the true value is likely to fall and indicates how accurate the statistic may be; the narrower the confidence interval, the more reliable the statistic. For example, in “Example: Figure 8” below, the “I” on the first vertical bar indicates that the statistics estimating poverty among whites in Marion County (14.8%) is fairly reliable; it is accurate to within 0.6 percent. In other words, given the underlying data, we are 95% confident that between 14.2% and 15.4% of white Marion County residents had household incomes below the federal poverty level. In contrast, the statistic estimating poverty among Hispanics is less reliable, accurate to within 2.3 percent (34.1%, 95% CI: 31.8-36.4). In general, as the amount of data used for a statistic increases, the statistic becomes more reliable, and therefore the confidence intervals get narrower.
