In her update on Monday night, First Selectwoman Lynne Vanderslice discussed new guidance issued for schools by the CDC, including new indicators and thresholds for determining the risk of transmission within the community. The new indicators replace the previous 14-day average daily per 100,000 indicators.
The first metric is Total New Cases per 100,000 people in the past seven days. This is calculated by adding the total number of cases in the past seven days, dividing by the population, and then multiplying by 100,000.
The second indicator is Percentage of NAATs (including PCR) that are positive during the past seven days. This is calculated by taking the total number of positive cases in the past seven days and dividing by the total number of diagnostic tests taken in the last seven days.
CDC Indicators and Thresholds for Community Transmission of COVID-19 Indicator Low Transmission Moderate Transmission Substantial Transmission High Transmission Blue Yellow Orange Red Total new cases per 100,000 persons in the past 7 days 0-9 10-49 50-99 ≥100 Percentage of NAATs that are positive during the past 7 days <5.0% 5.0%-7.9% 8.0%-9.9% ≥10.0%
The CDC guidance states that if the two indicators suggest different levels, the higher threshold should be considered when determining mitigation strategies.
Low Transmission Blue Moderate Transmission Yellow Substantial Transmission Orange High Transmission Red All schools: Universal and correct use of masks is required; physical distancing; handwashing and respiratory etiquette; cleaning and maintaining healthy facilities; contact tracing in combination with isolation and quarantine. Diagnostic testing: Symptomatic students, teachers, and staff and close contacts referred for diagnostic testing K-12 schools open for full in-person instruction. Physical distancing of 6 feet or more to the greatest extent possible Elementary schools in hybrid learning mode or reduced attendance. Physical distancing of 6 feet or more is required Middle and high schools in hybrid learning mode or reduced attendance. Physical distancing of 6 feet or more is required Middle and high schools in virtual only instruction unless they can strictly implement all mitigation strategies, and have few cases; schools that are already open for in-person instruction can remain open, but only if they strictly implement mitigation strategies and have few cases Sports and extracurricular activities occur; physical distancing of 6 feet or more to the greatest extent possible Sports and extracurricular activities occur with physical distancing of 6 feet or more required Sports and extracurricular activities occur only if they can be held outdoors, with physical distancing of 6 feet or more Sports and extracurricular activities are virtual only
Wilton, Fairfield County and the State of Connecticut were all Red-High Transmission with the following total seven-day new cases per 100,000 based on cases reported as of 8:30 p.m. on Feb. 14. Positivity indicated Blue-Low Transmission.
- Wilton: 120
- Fairfield County: 190
- State of CT: 180
Even though levels are high, Vanderslice reported that the rate of transmission is slowing in Wilton, Fairfield County and the state versus January’s rates.
She also cautioned that “unfortunately, health officials across the country continue to warn that by mid-March the “U.K.” variant (B.1.1.7) will be the dominant virus.
On Monday, Feb. 15, CT Department of Public Health announced the first Connecticut case of the “South African” variant (B.351). The patient is a resident of Fairfield County, aged between 60 and 70 and had not been outside the area.
