DOHMH Covid-19 Milestone Data: Percent of NYC residents tested who tested positive
This dataset shows daily citywide counts of persons tested by nucleic acid amplification tests (NAAT, also known as a molecular test; e.g. a PCR test) for SARS-CoV-2 , counts of persons with positive tests, and the percent positivity. Also included is a calculation of the average percent positivity over a 7-day period. NAAT tests work through direct detection of the virus’s genetic material, and typically involve collecting a nasal swab. These tests are highly accurate and recommended for diagnosing current COVID-19 infection. After specimen collection, molecular tests are processed in a laboratory, and results are electronically reported to the New York State (NYS) Electronic Clinical Laboratory Results System (ECLRS). Test results for NYC residents are then sent electronically to NYC DOHMH. There is typically a lag of a few days between when a specimen is collected and when a result is reported to NYC DOHMH. Data is sourced from electronic laboratory reporting from NYS ECLRS. All identifying health information is excluded from the dataset.

Freshness
The publisher's promise
How the agency that publishes this data says it keeps the data current.
OverdueNo automatic refresh
- Automatic refresh
No scheduled refresh runs for this dataset. A refresh you ask for on this page runs anyway.
The publisher set a regular schedule for this dataset but has not updated it for far longer than that schedule, so the automatic queue skips it. An hourly triage lifts this fence once the publisher updates it again, which takes up to about 7 hours 15 minutes.

Columns
Each source column, with the name and type we use to store it.
The publisher has not provided a data dictionary.
0 of 6 columns carry a concept; 0 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.
