Louisiana Notes

When Louisiana reports no data, several days of data, or unusual data (such as decreases in values that should increase), our volunteers note it here on the date the anomaly occurred. We also note here changes in our own methodology that affect the data.

Louisiana reports probable deaths on a weekly basis.

Negative test results reported in our API and CSVs are calculated by subtracting Confirmed cases from Total tests (PCR) in the absence of better data.
