Articles from the Main stream media like The Sydney Morning Herald suggest that the Delta variant, the strain behind Sydney’s latest outbreak, is about twice as infectious as the original coronavirus Australians dealt with last year. But it is still not known whether it is more virulent, or if it will cause more severe disease or death.

The most recent evidence from the UK shows the Delta fatality rate is about 0.3 per cent, compared to about 2 per cent for the earlier Alpha variant, said Professor Gregory Dore, an infectious diseases physician and epidemiologist at the Kirby Institute.

“People under 40 are the largest group being infected with Delta in the UK right now, partly because the majority of people over 50 are vaccinated and treatments have improved over time,” said Professor Dore. “But there is no evidence that Delta is more or less lethal than previous variants. It is just clearly more infectious.”

So why the continual lockdowns?
