The cities of Atlanta and Sandy Springs together saw 258 new COVID-19 diagnoses between May 22 and May 27 update reports from the Fulton County Board of Health. The diagnoses increased in all of the main ZIP codes in Buckhead and Sandy Springs.

The May 27 report includes some new key statistics: the numbers of new diagnoses of residents in each area within the past 14 days, and the percentage that occur in long-term care facilities, which statewide have been a hotbed of COVID-19 infections.

It is unclear 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 261 cases and their home city was unknown in 460 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
