Level of Community Transmission:

Also referred to as “transmission rate” or “rate of community spread.” This indicator is defined by the CDC as the "total number of new cases per 100,000 persons within the last 7 days," and is used to guide jurisdictions in measures needed to address the level of transmission. Low=<10, Moderate=10-49, Substantial=50-99, High=100+.

When the level is High (100+), the CDC recommends that, "significant measures are needed to limit contact between persons, with priority given to maintaining essential community activities and services." The TCHD announced the Level of Community Transmission was at Substantial on July 30, and High on August 20. See also

TCHD: Tompkins County Health Department  |  CHS: Cayuga Health System
ECLRS: Electronic Clinical Laboratory Report System (NYSDOH)

(Updated: February 5, 2021)

Total Tests for COVID-19

Total tests for Tompkins County residents. All higher education testing data to date is included in the Health Department’s daily update.

Daily Tests

Daily tests are positive and negative test results from ECLRS, the Electronic Clinical Laboratory Report System at the NYSDOH. The number reported here is for the previous day.

New Positive Cases

TCHD reports new unique positive cases daily based on a secure State system. TCHD nurses follow-up with any individual who has a positive test result and conducts a contact investigation

Total Unique Positive Cases

This is a cumulative number of unique positive cases since 3/14/2020. It includes active cases and those who have been released from isolation.

Released from Isolation

TCHD nurses report this number based on individuals who tested positive, have resolved symptoms, and are released from isolation.

Active Cases

Calculated as the total number of positive cases minus the totals of both released cases and deaths.

Active COVID-19 Hospitalizations

CHS reports all COVID-related hospitalizations daily to TCHD. TCHD then reports active COVID-19 patients — those being monitored during the isolation period. Patients who are released from isolation, but are still recovering in the hospital are not included in this number. CHD reports all COVID-related hospitalizations on their website

Total TC Resident Deaths

The Medical Examiner reports this information to TCHD. As of 1/25/21, TCHD is no longer reporting non-resident deaths. The counties of residence report these deaths.

The difference between "death data" reported by NYS and by TCHD is due to several issues. The State is likely reporting deaths of anyone who dies in Tompkins County regardless of their permanent address, whereas TCHD is reporting deaths of Tompkins County residents only. We are basing our reporting on death certificates, however we do not receive notification of deaths of residents who are not in Tompkins County at the time of death.

Total Vaccinations (1st and 2nd doses)

COVID-19 vaccinations are reported by Cayuga Health System. The totals are vaccinations administered at the Cayuga Health/TCHD Vaccination site and at Cayuga Medical Center only.
