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

As of July 29, the part of Atlanta within Fulton County had 7,705 COVID-19 diagnoses, up from 7,431 on July 27. Sandy Springs had 1,456 diagnoses, up from 1,372.

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 21.5% and in Sandy Springs the 14-day trend was down by 17.3%.

The Reporter’s last coverage of the Fulton report was July 24. There was an intervening report on July 27, but it contained outdated numbers in some categories carried over from a July 22 report and the county was unable to clarify whether there were other errors. The July 29 report appears to contain accurately updated numbers.

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 688 cases and their home city was unknown in 1,899 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 July 29 was 16,781. Of those, 381 are reported as having died. About 10% of patients were hospitalized and about 2.3% died. Countywide, residents and staff of long-term care facilities account for about 9.8% of diagnoses and 50.7% of deaths.
