Will new Covid-19 wave in Australia mean return to masks?
Australia is in the midst of a new COVID-19 wave, with significant increases in case numbers recorded across the country in the past week.
New cases have jumped by 63 percent in Victoria from 10,226 to 16,636, while weekly infections in NSW have risen by more than 7,000 to 19,800.
Hospitalisations are increasing as well, with the number of patients being treated in Queensland doubling in just seven days.
Professor Adrian Esterman, chair of biostatistics and epidemiology at the University of South Australia, said that's because there are three big things happening at the same time.
The first is that many people in Australia have waning immunity from vaccination and previous infection.
"It's now seven months since my last dose, and that means that by now I have a much-reduced protection against COVID-19, and that includes serious illness and death," Professor Esterman told SBS News.
"So although I'll still have some protection, it’s nowhere near as strong as it was seven months ago, and many people are in that situation."
The second is that new Omicron subvariants have arrived in Australia, including XBB and BQ.1.
"They've really taken over in places like Singapore and France, and they're starting to take over here," Professor Esterman said.
"[The subvariants] are much more transmissible than BA.5, they're much better at evading our immunity, and they would alone cause an increase in cases, never mind waning immunity."
The final thing in the mix is the removal of public health measures, such as mandatory isolation and mask-wearing in indoor settings.
