Genome sequencing so far suggests all the latest community cases of Covid-19 are linked, which indicates a single source of infection, Dr Ashley Bloomfield says.
Auckland moved into alert level 3 for seven days from 6am today, with the rest of the country going to alert level 2.
Covid-19 Response Minister Chris Hipkins confirmed today that genomic sequencing linked the latest community cases of Covid-19 in Auckland to the second family in the South Auckland cluster.
The cases have resulted in Auckland going to alert level three for seven days, and the rest of the country to level two.
Speaking to media this afternoon, Dr Bloomfield said the genome sequencing showed cases “M” and “N” were not casually connected – this was a direct link which narrowed down the chain of transmission.
Dr Bloomfield said Auckland Public Health officials were still trying to track down a single source of infection that has led to the community cases.
He said wastewater testing has not been able to find wider community cases of Covid-19.
