All data updated Wednesdays at 4PM except holidays, unless otherwise noted. Some data sources do not provide daily updates. The last 2021 update was Dec 21. A special New Year update is planned for Jan 3, 2022. Regular weekly updates will resume on Jan 5, 2022.
Last updated . Data source: CDC COVID-19 Data Tracker. Data shown above includes the cities of Columbus and Worthington. Please note that the calculated rates are based on the most accurate data available at the time.
| Indicator* | Low Transmission: Blue | Moderate Transmission: Yellow | Substantial Transmission: Orange | High Transmission: Red |
|---|---|---|---|---|
| Total new cases per 100,000 persons in the past 7 days | 0–9.99 | 10–49.99 | 50–99.99 | ≥100 |
| Percentage of NAATs1 that are positive during the past 7 days | 0–4.99% | 5–7.99% | 8–9.99% | ≥10% |
*If the two indicators suggest different transmission levels, the higher level is selected.
1NAAT remains the “gold standard” for clinical diagnostic detection of SARS-CoV-2 and includes viral testing such as Nucleic Acid Amplification Tests (NAATs), which include reverse transcriptase-polymerase chain reaction (RT-PCR) tests. Total number of new cases per 100,000 persons within the last 7 days is calculated by adding the number of new cases in the county (or other administrative level) in the last 7 days divided by the population in the county (or other administrative level) and multiplying by 100,000. Percentage of positive diagnostic and screening NAAT during the last 7 days is calculated by dividing the number of positive tests in the county (or other administrative level) during the last 7 days by the total number of tests resulted over the last 7 days. If the two indicators suggest different transmission levels, the higher level is selected. Transmission categories include Blue (Low Transmission): Control is achieved largely through individual prevention behaviors and the public health response to identify and isolate cases or clusters. Threshold: Counties with fewer than 10 cumulative cases per 100,000 population in the past 7 days, and a cumulative NAAT percent test positivity result below 5% in the past 7 days. Yellow (Moderate Transmission): Adherence to individual and selected community level prevention strategies are needed. Threshold: Counties with 10-49 cumulative cases per 100,000 population or a cumulative NAAT test positivity result between 5.0-7.9% in the past 7 days. Orange (Substantial Transmission): Everyday activities should be limited to reduce spread and protect the health care system. Threshold: Counties with 50-99 cumulative cases per 100,000 population or a cumulative NAAT test positivity result between 8.0-9.9% in the past 7 days. Red (High Transmission): Significant measures are needed to limit contact between persons, with priority given to maintaining essential community activities and services (e.g., health care, transportation, food and agriculture, schools). Threshold: Counties with cumulative cases =100 per 100,000 population or a cumulative NAAT test positivity result =10.0% in the past 7 days. The Level of Community Transmission table display the number of counties in each level and the change from the prior week.
Excludes the cities of Columbus and Worthington.
ODH updates their numbers at 2 pm everyday and may not include our case counts at this time. For state case count, go to https://coronavirus.ohio.gov.
NOTE: As of September 1, 2021, criteria to distinguish a new case has changed. For more information, please see the Ohio IDCM.

What to look for: Shows whether the trend in cases is increasing or decreasing by the number and rate of COVID-19 over time.
Beginning in mid-October, the decrease in percent of cases linked to another known COVID-19 case is likely caused by the surge in virus spread and subsequent increase of cases in the community. When community-wide spread increases and numbers of new cases exceed the capacity to investigate cases, knowing if a person with COVID-19 is linked to another person with COVID-19 decreases.
What to look for: High percentages are good, and 80% or greater is best. Note that the measures for the most recent 4 weeks tend to be less accurate because of delayed information reporting and collection.
What to look for: The goal is to have greater than 80% of tests reporting results to public health within 48 hours. When test results take more than 48 hours to report, the effectiveness of helping people with COVID-19 and people they may have infected decreases. Note that the measures for the most recent 4 weeks tend to be less accurate because of delayed information reporting and collection.

Cases by race and ethnicity are updated as additional data are available. Race and ethnicity categories will not align exactly with population totals because of incomplete data.
What to look for: Significant differences between the “% of all cases” and “% of population” for each race/age group indicate potential inequities in how the disease is being contracted and/or treated. For example, if 50% of all cases are among whites but whites are 75% of the population, then the data indicate non-white people are likely impacted more from COVID-19. Note that the measures for the most recent 4 weeks tend to be less accurate because of delayed information reporting and collection.
Note: Excludes case counts <11
