“The other problem identified by Chant is authorised workers infecting each other, and then seeding new households. The NSW government is prioritising them for vaccination, which is wise, but this will take time.

McLaws suggests that rapid antigen testing in workplaces could help drive down case numbers in the interim. She says many of the test brands are accurate in identifying positive cases but throw up false positives, which means some workers may be off work while they have a follow-up PCR swab.More recently childcare centres have emerged as a problem. But is it family daycare or large centres? Is it transmission among staff, children or parents?We don’t know, unfortunately, because we are getting less information about the shape of the outbreak in NSW, not more.It might be necessary to strictly limit childcare only to the children of authorised workers. Or it might be solvable by rapid antigen testing.”
