Trend in daily positive tests

This graph shows how the number of daily positive tests over the last seven days has developed relative to the previous seven days. This is known as the Growth rate (or G rate). A positive Growth rate (red bar) indicates that more people have been testing positive. A negative Growth rate (blue bar) indicates that fewer people have been testing positive.

Percentage of positive test results at GGD test locations

The figures below provide information on the overall number of tests conducted at GGD test locations and the percentage of positive results. An increase in the percentage of positive tests could be an indication that transmission of the virus is on the rise. Please note that most but not all tests are conducted by the GGD. This means that the total number of people who have tested positive differs from the number of people who have tested positive at GGD test locations.
