LYME/OLD LYME — The Daily Data Report for Connecticut issued Thursday, Sept. 23, by the Connecticut Department of Public Health  (CT-DPH) for data as at 8:30 p.m. Wednesday, Sept. 22, contains bad news 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 third week in succession that both towns have found themselves in the Red Zone. See detailed description of the zones in italics below.

Other signs are more positive for our towns, however. Lyme now has an Average Daily Case Rate of 18.5 (down from 43.2 on Thursday last week) while Old Lyme’s is 22.5 (down from 30.3 on Thursday last week.) A rate over 15.0 places a town in the Red Zone.

Statewide, there is also some good news. Connecticut’s daily positivity rate now stands at 2.28 percent down from 2.93 percent on Thursday last week.

Also, statewide, the latest average daily rate of new cases of COVID-19 by town during the past two weeks (see map above) has continued to slow marginally with 81 towns now in the Red Zone, which is three down from last week’s total of 84.  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 no new, confirmed COVID-19 cases Thursday, Sept. 23, compared with Wednesday, Sept. 22. keeping Old Lyme’s cumulative total of confirmed cases at 419. This is the first day that there has not been a single new case reported in a 24-hour period in Old Lyme since Aug. 26.

Lyme also reported no new cases on Thursday, Sept. 23, and therefore maintained its cumulative total of 129 for the fourth day in succession.

On Aug. 26, the cumulative number of cases in Old Lyme was 372 meaning 47 cases have been reported since that date, while 12 have also been confirmed in Lyme during the same period.

Weekly Report from Ledge Light Health District (LLHD)

Stephen Mansfield, LLHD Director of Health,  prefaced the weekly LLHD report sent out Sept. 23, with these words, “We are happy to see a decrease in the number of new COVID cases, and relatively stable numbers over the previous few weeks.”

He added, “It is imperative that we remain diligent in our mitigation strategies. We strongly advise everyone to wear masks indoors in public settings, regardless of vaccination status”

Mansfield also noted, “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, North Stonington and Groton are in the Orange (second highest) Zone.
