 # The 2021 Delta outbreak locations of interest
-Here's [another dataset](loi.geojson?raw=true) pertaining to Aotearoa's SARS Covid-19 pandemic experience. This one is the Ministry of Healths's locations of interest as collated by me from August to October last year. The official published list was always 'current'. This list, was assembled over time so that early locations were not dropped when they were no longer of interest.
