*Yesterday we reported 13 community cases, however in today’s reporting of yesterday’s cases who were infectious in the community, we are reporting 15 – this is due to two different data systems and a small lag in data reportage.

**Recovered cases can continue shedding viral matter for weeks after recovering.
With more than 700 recovered cases linked to this outbreak, we will see detections of Covid-19 in wider wastewater that are likely linked to recovered cases. Nonetheless, public health officials will continue to investigate positive detections and take urgent repeat samples where appropriate.
