The first Delta-variant outbreak in the community brings a new challenge to Aotearoa New Zealand’s COVID-19 response. A Delta outbreak was in some respects a likely scenario given the high infectiousness of this variant and the emerging evidence that vaccines may be less effective at preventing Delta transmission compared with the original strain of the pandemic virus. In this blog we discuss public health responses employed in other jurisdictions in response to the Delta variant that may be beneficial in controlling the current Delta outbreak in NZ and strengthening NZ’s COVID-19 response in future.

The importance of indoor aerosol transmission of the virus that causes COVID-19 is increasingly recognised. In addition to public health measures such as masking and physical distancing, further protections are needed to prevent the spread of the virus. Interventions to improve ventilation and filtration are needed for indoor settings in Aotearoa NZ. In this blog we address the particular need to improve ventilation in three settings: (i) homes with contacts who are self-isolating; (ii) indoor workplaces that have essential workers; and (iii) MIQ facilities.
