NORWALK — The city on Tuesday confirmed 68 new cases of the coronavirus — the highest single-day total since April.

“Our positive cases are rising, as they are across the state and across much of the country,” Mayor Harry Rilling said. “We are back to seeing numbers in Norwalk that we had in April. I encourage all of us to stay focused, be extra cautious, and not lose sight of the fact that this virus is very contagious. Every resident has to take precautions now to try and slow this virus down otherwise things will become much worse as we head deeper into the fall and winter.”

According to the Norwalk Health Department, there has been an average of 31.1 daily positive cases per 100,000 residents over the last seven days and a 22.4 average over the last two weeks. The city said they’re analyzing cases per 100,000 residents to help track incidence rate and compare this to other communities.

The 68 new cases on Tuesday was the highest since 81 were reported on April 26. It came as the state’s positivity rate on Tuesday reached 3 percent for the first time in months.

There have now been 2,588 cases of COVID-19 reported in Norwalk since March with at least 129 new cases reported last week. Norwalk Health Department officials have said they don’t have data on how many people recovered because there’s no set definition of recovery from the new virus and many people recover at home.

There were no new deaths reported on Tuesday. Norwalk has lost 149 residents to coronavirus since March. The most recent death was reported on Oct. 5.

The city is offering free drive-through COVID-19 testing on Saturday from 10 a.m. to 2 p.m. at the Stepping Stones Museum Parking Lot, 303 West Ave. No appointment, insurance, symptoms, or doctor’s note is required to get tested. The courts and playground at Mathews Park will be closed for the day.

Rilling there is no “one apparent cause or event” to blame for the recent rise in cases, although Norwalk Public Schools, which has reported at least 22 COVID cases over the last week, found transmission was happening during social gatherings outside of school. The Norwalk Health Department officials said they’ve see similar trends.

Rilling urged residents to limit non-essential trips to the store, only have one member per household run errands, socially distance and wear a mask to lessen change of exposure.
