When Puerto Rico 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.

Reported Deaths include both confirmed and probable COVID-19 deaths.

Puerto Rico does not report test data on its data dashboard. Data for Total PCR Tests (in specimens) and Positive PCR Tests (in specimens) is taken from infrequent press reports.

Puerto Rico’s Recovered numbers occasionally decrease without explanation. We suspect this is due to some sort of data quality assurance or de-deduplication.

On November 7, 2020, Puerto Rico switched from using antibody tests to antigen tests to identify probable cases in accordance with August 2020 CSTE guidelines. This caused probable cases to drop by 33,888. We cleared the history of our Probable Cases field to match the new definition. We also modified our Cases (confirmed + probable) field to remove probables identified via antibody from April 24, 2020 onward, when we have access to a breakdown.

On November 2, 2020, Puerto Rico removed 551 recoveries without explanation.

On July 7, 2020, we updated Negative PCR tests based on press releases from May and June.

On May 6, 2020, Puerto Rico stopped reporting Negative PCR tests.

On April 22, 2020, Puerto Rico's data changed due to deduplication. This resulted in a decrease in Total cases.
