We need to keep social distancing and avoiding indoor spaces, even if the official rules have changed. A microbiologist explains why.
With COVID-19 spreading in Sydney's southwest, can New South Wales avoid a return to lockdown and a similar scenario to Victoria's second wave? The answer depends on whether there is community spread.
The surge of cases in Victoria is inviting speculation into how the state and federal governments could have acted differently.
Many people are already struggling amid the stress and uncertainty of the pandemic. For Melbourne residents, a second lockdown is likely to place an even bigger strain on their mental health.
There's no scientific definition for a wave of disease – and no evidence that the original onslaught of coronavirus in the US has receded much at all.
Victoria has recorded its largest single-day increase in COVID-19 cases. It might be time to return to a statewide lockdown.
Cramped living conditions, a lack of social distancing and informal businesses staying open during lockdown may have come together to drive up the city’s infection rate.
The recent spike in new coronavirus cases in the US is not due to a second wave, but simply the virus moving into new populations or surging in places that opened up too soon.
As provinces throughout Canada start to enter Phase 2 of its reopening, mathematical models can help predict and control the spread of COVID-19 with the help of contact tracing.
Over the past week, we've seen more than 100 new cases of coronavirus in Victoria. What's going on?
There is no evidence that COVID-19 will occur in waves.

K is all about the super-spreaders.
This winter, the field of respiratory viruses will be crowded.
The national curve is made up of much smaller local curves with their own peaks at different times – but deaths are still definitely falling.
Differences in the viruses' biology and societal contexts mean there's no guarantee today's pandemic will mirror the 'waves' of infection a century ago.
Getting the control measures right is critical.
Testing and isolating cases only after they develop symptoms might not be enough to prevent further outbreaks of COVID-19. Sentinel surveillance, by testing randomly in the community, can go further.
When an outbreak is brought under control, it's possible only a small proportion of the population has been infected and gained immunity. This can set the scene for a second wave of infections later.
