Evolution explains why the Delta variant spreads faster than the original Wuhan strain. It explains what we might see with future variants. And it suggests how we might step up public health measures.
A$50 million could provide all NSW school classrooms with air purifiers with HEPA filters. This pales compared to the roughly $220 million-a-day cost of Sydney’s lockdown.
As troops enforce Sydney’s lockdown, two experts explain why using military rhetoric and personnel may undermine efforts to control the virus, especially among communities most vulnerable to COVID.
We found two small air cleaners in a single hospital room could clear 99% of potentially infectious COVID aerosols within 5.5 minutes.
In Africa, it’s more rational to prioritise vaccine access, rapid rollout and community engagement, than pushing the narrative of vaccine-induced population immunity.
Many long COVID sufferers are reporting having ‘brain fog’, where they can’t concentrate as well as they used to.
NSW needs to mandate masks outdoors, provide adequate financial support, set up a ‘ring of steel’, use rapid tests for essential workers, and ensure cases not in full isolation get to zero, among others.
20-39 year olds are ‘peak spreaders’. If we vaccinate them, it reduces the risk for all of us.
When politicians and others speak about herd immunity, unfortunately, they are under the misconception that the current tools that we’ve got are adequate to eliminate the virus.
The circulation of misinformation about the COVID-19 vaccine poses the danger of hampering the government’s efforts to control the pandemic.
Vaccines can’t provide 100% protection, so it’s not a failure or surprise when some vaccinated people get sick with COVID-19. The good news is their cases are much less likely to be severe or fatal.
The CDC guidance applies to areas with high coronavirus transmission rates – which on the day of the announcement covered 63% of US counties.
What kind of vaccine is Sputnik V, how does it work, and what data are we missing?
Once we achieve herd immunity, people who are not vaccinated benefit indirectly from the immunity of those around them. But it’s not easy to say exactly when we’ll reach this threshold for COVID-19.
Parents face tough choices since young kids can’t yet get COVID-19 vaccinations. An infectious diseases expert offers guidance on navigating summer activities.
New studies show men who have had COVID-19 could face serious reproductive health issues.
The evidence shows the main way COVID-19 spreads is through the air. I propose 3 steps Australia needs to take to protect people from infection risk and other indoor air hazards.
NSW’s successful test and trace strategy controlled the Crossroads Hotel outbreak a year ago without needing a stringent lockdown. But this has not worked as well against Delta.
Policymakers need to make sense of the data so as to predict and manage what’s happening. To address this need, we developed a visualisation tool to track and predict country-level COVID-19 cases.
