There’s no need to pull out the candy catapult this year, but a few reasonable precautions can keep COVID-19 transmissions in check.
Dealing with what have been called ‘wicked’ and ‘adaptive’ problems is a huge challenge for political leaders. A ‘clumsy’ response can be inevitable – and even desirable.

Recent computer modeling shows the upcoming flu season might see a surge in cases. Coupled with COVID-19’s continued threat, doctors are again urging Americans to get their shots.
With the government decision on alert levels due today, it’s clear a more radical approach to vaccination is needed — including restrictions for eligible but unvaccinated people.
Delta is more contagious and appears to be more deadly. And it’s more likely to land those infected in hospital and intensive care. Here’s what the latest evidence says about the dominant variant.
Public health officials have been waiting for good data before making any decisions about booster shots for people who received Johnson & Johnson’s Janssen COVID-19 vaccine.

The biggest challenge to the health system is the war in Tigray and other insecurity all over the country. Conflict has made COVID-19 prevention and vaccination efforts impossible in many areas.
Until this year it looked as if Australia could have its cake and eat it too — low deaths form COVID and a resilient economy.

The federal election is taking place during a fourth wave of COVID-19, and border management remains crucial to controlling the pandemic. Here’s how each major party would manage travel restrictions.
The rules dividing states and territories are likely to remain in the short term. But as time goes on and vaccination rates increase, many may stop trying to reach COVID-zero too.

Making rapid antigen tests for COVID-19 cheaper and more accessible can catch the infectious cases before they spread and help everyone resume normal activities safely.
The huge number of active coronavirus infections offers plenty of opportunity for mutations to occur and new variants to arise.

It’s not spreading widely, and it’s not at Australia’s doorstep. The tools we have in place work against the coronavirus.
We are being cautious about the implications for vaccine efficacy and transmissibility while we gather more data to understand this lineage.
To reduce the spread of COVID-19 in unvaccinated children, epidemiologists rely on a layered approach of interventions including masking, ventilation, cohorting and promoting vaccination for all eligible community members.

With no vaccination yet in children under 12, preventing COVID-19 spread in schools depends on fine-tuning policy interventions according to local epidemiology and vaccination rates.
