The cities of Atlanta and Sandy Springs together saw 364 new COVID-19 diagnoses between Sept. 22 and Sept. 29 update reports from the Fulton County Board of Health.

The number of cases increased in all of the main local ZIP codes. The 14-day trend declined in both cities and was down in all but one of the local ZIP codes.

A chart of COVID-19 diagnoses by city in Fulton County as shown in a Sept. 29 Board of Health report.

The report includes a significant downward revision of countywide death totals from the pandemic. Tallied on Sept. 18 at 560 deaths, the number is now reported as 514 confirmed dead. A previous report said that more than 40 fatalities were being reviewed by Georgia Department of Public Health to confirm the cause of death.

As of Sept. 29, the part of Atlanta within Fulton County had 11,744 COVID-19 diagnoses, up from 11,460 on Sept. 22. Sandy Springs had 2,437 diagnoses, up from 2,357.

Atlanta remains the number one city in the county for COVID-19 diagnoses at 42.5% of the total, and Sandy Springs remained third with 8.8% of the total.

The 14-day trend in new COVID-19 in each city is charted in the report, calculated by comparing the 14 days preceding the previous seven days with the 14-day period before that. In Atlanta, the 14-day trend was down by 19.6% and in Sandy Springs the 14-day trend was down by 17.2%.

The Sept. 29 report and an intervening Sept. 25 report were not published on the county website until the Reporter requested copies from a county spokesperson. To view the full reports, see the county website here.

The report does not state whether the numbers reflect the coronavirus’s spread, the state of testing, or both.

The statistics, which are based on patients’ home addresses, are not completely accurate due to such factors as a large number of patients whose cities or ZIP codes are unknown. Of those diagnosed, their ZIP code was unknown in 750 cases and their home city was unknown in 3,039 cases. All numbers are preliminary and may be adjusted later, including through “data cleaning” — the reassignment of some cases to a different ZIP code or city after further analysis.

The total number of confirmed COVID-19 diagnoses in the county as of Sept. 29 was 27,635, up from 27,097 on Sept. 22.
