So what's the deal with this new coronavirus strain in Adelaide?
South Australia has started its first day of a strict six day lockdown that health authorities have described as a "circuit breaker" to stamp out Adelaide's coronavirus outbreak. So far, the number of new cases remains relatively small. But authorities are worried they're dealing with a variant of the SARS-Cov-2 virus which moves much more quickly and patients don't show symptoms. So how likely is it that the virus has changed and is now far sneakier? And will the six day lockdown solve the problem?
