With 27 locally acquired cases identified in the 24 hours before Wednesday, this decision isn’t surprising. Of some concern, seven of these people had been moving around in the community during part of their infectious period. Another seven appear to have been in the community for the whole of their infectious period. These aren’t the numbers you want to be seeing when considering emerging out of a lockdown. So what are health authorities looking for when when making decisions about relaxing restrictions? The first key factor is whether the public health team is identifying the epidemiological links between cases. The second is whether contact tracers are able to identify all potential cases and quarantine them before they’re infectious. This is clearly not yet the case in NSW.
