As of May 27, the Best-dos Santos Public Health Laboratory has completed 5,038 tests to date. Barbados tests for SARS-CoV-2, the virus that causes the coronavirus disease 2019 (COVID-19).

Fewer people have been tested that the number of tests completed because one person alone has to be tested at least twice more if they test positive. This is in order to get the required two consecutive negatives after 14 days in isolation to be considered recovered. However, Loop News knows that in some cases, one patient had to be tested 12 times before being deemed recovered.

Since the Centres for Disease Control and Prevention (CDC) changed the way the per cent positivity rate is calculated last week (May 23), Barbados now has a per cent positivity rate of 0.019.

The per cent positivity rate was previously calculated as the number of positive COVID-19 cases divided by the total number of tests completed. The new calculation is the number of positive cases divided by the number of people tested not the number of tests done. Barbados would have been looking at a per cent positivity rate of 0.0182 under the old calculation.
