Percent of tests that are positive is a helpful indicator in understanding the spread of infection in a community.
It indicates the total number of specimens tested, including when an individual is tested more than once. This metric is widely used by other states and the Federal government, and is therefore useful to compare Delaware to other jurisdictions.
Data for percent of tests that are positive are based on the testing date. There is a two-day lag for presenting data related to percent of tests that are positive to account for the time delay between the date of the test and the date that DPH receives the test result.
