While this is a small dataset of tested individuals which may be proportionally representative to larger groups, it comes at odds with releasing PII with respect to individual privacy to see potential comorbities (old age, obesity, diabetes, lack of an auto-immune response, etc). We know that people with exposure to recycled airspace and live in close proximity are more likely to transmit covid to one another. Mask wearing and social distancing are actions that will have to be obeyed by everyone as a collective in order to work-- one may never know if they're an asymptomatic super-spreader without widespread testing. Cloth masks aren't for protecting yourself as much as they are everyone around you.
Within the data itself, it shows that quarantine and isolation are effective practices against spreading covid in a hotspot. This may be a good stop-gap measure while researchers are able to study it more, but government's responsibility at all levels of keeping people safe in returning to work has has greatly fallen short of expectations.
