The last Omicron wave affected younger people. But the new BA.5 variant is seeing case numbers in older age groups higher than ever before – just as hospitals are under the most pressure.
Is it time for a new generation of COVID vaccines? Here’s where the research is at.
Achieving herd immunity via vaccination was always going to be a hard ask. Now it’s mathematically impossible.
Understanding the depth of vaccine hesitancy, and the drivers behind the lack of take-up is critical to preventing further deaths, infections, and continuing harm to the economy.
The COVID isolation period is seven days in Australia, but you might still be infectious after that if you have symptoms and a positive RAT.
The COVID-19 vaccines continue to be effective against severe illness leading to hospitalization and death in all age groups, including children ages 5 to 11.
What’s the difference between a variant and a subvariant? It’s all in the behaviour.
At this stage of the pandemic complacency is likely to lead to an increase in cases, hospitalisation, morbidity and mortality.
Repeated resurgences of SARS-CoV-2 transmission are expected in the years to come.
After reporting zero COVID cases until now, North Korea is facing a rapidly-spreading outbreak of the omicron variant. Here’s how things could play out.
With the relaxation of mask-wearing mandates, there’s even more need to know how much over-the-counter tests help.
It’s hard to keep up. But new Omicron sub-variants are emerging that may lead to reinfections and another spike in cases.
