July 24 2020 Heat map: COVID-19 by postcode in northern suburbs of Wollongong
The heatmap presents data on cases (by notification date) and the number of tests carried out for the last 14 days.
For cases, the postcode is based on the location of usual residence, not necessarily where the virus was contracted.
The postcode of people tested is based on the address they reported at the time of the test.
Information on active cases** or tests carried out recently (i.e. in the last 14 days) is displayed by selecting the ‘Recent’ radio button.
** Active cases are locally acquired COVID-19 cases with onset in the last four weeks. This is based on the date the person first developed symptoms.
***The heatmap excludes 189 cases in crew members who tested positive while on board a ship docked in NSW at the time of diagnosis.
When no date of symptom onset is available (it is either under investigation by public health staff or the person tested positive without showing symptoms), the date of the positive test is used. Infections are not always acquired in the place of residence as people often travel outside their area for many reasons (e.g. work, school and shopping).
From 5 June, this heatmap will report on the number of tests notified instead of the number of people tested.
From 24 June, this heatmap reporting of active cases has changed to locally acquired COVID-19 cases with onset in the last 4 weeks.
