LYME/OLD LYME — The Daily Data Report for Connecticut issued Thursday, Sept. 16, by the Connecticut Department of Public Health (CT-DPH) for data as at 8:30 p.m. Wednesday, Sept. 15, has more distressing data for Lyme and Old Lyme.
It shows that both towns remain in the Red (highest) Zone for the average daily rate of new cases of COVID-19. This is the second week in succession that both towns have found themselves in the Red Zone. See detailed description of the zones in italics below.
Lyme now has an Average Daily Case Rate of 43.2 while Old Lyme’s is 30.3. A rate over 15 places a town in the Red Zone.
Connecticut’s daily positivity rate now stands at 2.93 percent, down from 3.36 on Thursday last week.
Despite this poor situation locally, statewide, the latest average daily rate of new cases of COVID-19 by town during the past two weeks (see map above) has remained pretty constant over the past week with 84 towns now in the Red Zone, which is only one higher than last week’s total of 83. On Sept. 2, the total was 91 so the trend is undoubtedly downward although it is still up significantly from the 39 reported on Aug. 12.
Old Lyme reported four new, confirmed COVID-19 cases Thursday, Sept.16, since the previous CT DPH report issued Wednesday, Sept. 15. This means Old Lyme’s cumulative total of confirmed cases rises to 411, while Lyme reported no new cases and therefore kept its cumulative total at 129.
On Aug. 26, the cumulative number of cases in Old Lyme was 372 meaning 39 cases have been reported since that date, while 12 have also been confirmed in Lyme during the same period. Lyme-Old Lyme Schools re-opened to students Aug. 26.
- The Gray category is defined as when the Average Daily Rate of COVID-19 Cases Among Persons Living in Community Settings per 100,000 Population By Town is less than five or less than five reported cases.
- The Yellow category is defined as when the Average Daily Rate of COVID-19 Cases Among Persons Living in Community Settings per 100,000 Population By Town is between five and nine reported cases.
- The Orange category is defined as when the Average Daily Rate of COVID-19 Cases Among Persons Living in Community Settings per 100,000 Population By Town is between 10 and 14.
- The Red category is defined as when the Average Daily Rate of COVID-19 Cases Among Persons Living in Community Settings per 100,000 Population By Town exceeds 15.
In all cases, this rate does not include cases or tests among residents of nursing home, assisted living, or correctional facilities.
Weekly Report from Ledge Light Health District (LLHD)
Jennifer Muggeo, MPH, who is currently LLHD Deputy Director/Acting Director while Stephen Mansfield is on vacation, prefaced the weekly LLHD report sent out today, Sept. 17, with these words, “This week’s numbers reflect outbreaks at both a daycare and an institution of higher education and outbreaks within households and congregate living situations as well as transmission associated with social gatherings.”
She added, “We strongly advise everyone to wear masks indoors in public settings, regardless of vaccination status”
Muggeo noted in addition, “LLHD encourages everyone 12 and older to get vaccinated. Information regarding vaccination opportunities and other relevant information can be found at Ledge Light Health District | Promoting Healthy Communities (llhd.org)
The nine towns included in the LLHD show the majority — including Lyme and Old Lyme — in the Red Zone. Only Stonington, East Lyme and Groton are in the Orange (second highest) Zone.
