While the focus has been on containing ‘hot spots’ of COVID-19 outbreaks, understanding why some areas have few or no cases could point the way to a staged reopening that starts with these areas.
Most aged care homes are designed to be naturally ventilated. But when windows are closed to keep out the cold, poor ventilation appears to be common – and that’s a problem for infection control.
You’re right to be concerned but we can’t draw too many conclusions from just one or two data points. Instead, we need to look at averages over multiple days.
Not everyone has a job they can do from home. Mapping the patterns of occupations across Melbourne’s suburbs against COVID-19 cases strongly suggests why some parts of the city are more vulnerable.
If you’ve got a test but haven’t heard back, it’s possible the delay is caused by test samples needing to be taken to interstate labs and the huge scale of testing underway.
The spread of the virus through households creates costs higher than for isolation in hotels when families are large and living at close quarters as in Melbourne’s public housing towers.
As governments start to return to a new normal, people with disabilities in care facilities are still in serious danger of being left behind during the coronavirus pandemic.
The internal density and layout of buildings are key factors in COVID-19 transmission risk. This is not an argument against high-density cities, some of which have successfully contained the virus.
