Darien Known COVID-19 Cases Jumps to 91, Town Reports More Darien Data

As of Thursday, April 2, the number of known cases of COVID-19 in Darien jumped from 77 to 91, an increase of 17 (or 18% over the previous day), according to a chart published Friday on the town government website.

The chart, showing the daily number of positive COVID-19 test results, is one of a series presented on a web page on the town website. Other charts on the page show the distribution of Darien COVID-19 cases by gender, age group and age group over time.

The hefty increase in the number of Darien cases is only in the number of known COVID-19 cases in town, not the actual number of cases (which is unknown), and it doesn’t come with an explanation of what factors might have resulted in the jump, such as possible delayed testing results from previous days or increased testing as more opportunities have become available to get a test.

In an interview Friday afternoon, Darien Health Director David Knauf was asked about those possible reasons for the jump in the case number and agreed that those factors are both possibilities. The rise in Darien COVID-19 case numbers “probably have more to do with the fact that more people are being tested,” Health Director David Knauf said Friday afternoon.

  • UPDATE, 5:31 p.m., Friday: The state Web page for testing results said a jump in the overall state COVID-19 test results reflects a catchup in data gathering, and “This increase does not reflect a change in the trajectory of the outbreak.”:
  • “As of April 3, 2020, a total of 4914 laboratory-confirmed cases of COVID-19 have been reported among Connecticut residents (Figure 1). Nine hundred and nine patients are currently hospitalized. One hundred and thirty-one residents have died. The increase in cases reported today is related to catch up of data entry and implementation of a new method for reporting cases to the Department of Public Health. This increase does not reflect a change in the trajectory of the outbreak.”

Knauf said he doesn’t have day-to-day information on the total number of people from Darien who get tested, getting either a positive or negative result for the presence of the COVID-19 virus.

Knauf said that if he could compare positive results with the total number tested, that would give some indication of whether the spread of the virus is speeding up, staying steady or slowing down, leading to a “flattening of the curve” that could result in hospitals avoiding being overwhelmed by a spike in cases.

Overall, Knauf said, information from Murphy Medical, the company doing testing at the Darien High School campus, indicates 10% to 15% of the tested in Darien test positive, but Knauf doesn’t have an indication of what changes may be taking place in that percentage, or similar data on COVID-19 tests done elsewhere of Darien residents.

The data in the charts represents people who test positive for COVID-19 and who are Darien residents, no matter where they’re tested, Knauf said.

The charts, which are labeled with the caveat “Data is preliminary and subject to change,” are published in this article, below.

Knauf said he hopes Darien residents who see the chart will be more likely to practice social distancing.

“I don’t think enough people are staying home,” he said. “People need to stay home. People need to socially distance themselves. I can’t overstate the importance of that.”

In addition to publishing the charts on Friday, the town website’s COVID-19 information is now available from a link in a red band at the top of the website home page.

The chart very roughly resembles an exponential growth curve, meaning more growth over time. In detail, the number of new cases has jumped up and down, but the overall trend is exponential growth.

The jump in cases on Thursday was not the largest increase in Darien COVID-19 positive results — on March 29, the number jumped by 27 — from 42 to 69 (a jump of 64%). In contrast, the next two days showed increases of only four cases a day.

Overall, the chart for Darien’s total number of cases looks roughly like exponential growth (a faster rate of growth over time) since March 20, when Darien had one identified case. The numbers of new cases, however, don’t show much of a pattern except a gradual increase over time.

Slightly more Darien women than men have tested positive for COVID-19, although that could be a result of more women being tested. This is consistent with statewide results, where the number of women who have tested positive (1,971) also is larger than the number of men (1,839).
