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.
As Los Angeles County again mandates masking indoors – even for the fully vaccinated – local health officials in the U.S. are closely eyeing their own COVID-19 vaccination and infection rates.
The US has split into “two Americas,” one of the unvaccinated and one of the vaccinated. The differences in deaths and hospitalizations between the two populations are striking.
Preliminary evidence suggests Lambda has an easier time infecting our cells and is a bit better at dodging our immune systems. But vaccines should still do a good job against it.

Gatherings can lead to the deaths of many people if coronavirus infections spread. It is important for people to stick to regulations such as those about avoiding close contact and confined spaces.
In Hong Kong, SARS created a new social norm, where people accepted mask use as part of their ‘civic responsibility’.
The good news is Victoria is more likely to reach zero case of community transmission sooner if vaccination rates pick up, even modestly.
COVID vaccines don’t contain any live virus to shed. Here’s the science to put the myth of viral shedding after the COVID vaccine to bed.
The microbiologist who directs the National Emerging Infectious Diseases Laboratories at Boston University explains all the biosafety precautions in place that help him feel safer in the lab than out.
Simulations of classrooms and offices can help determine the safest configurations to reduce the spread of COVID-19.
South Africa has clearly suffered the consequences of poor strategic decisions to this point. It doesn’t need to continue along these lines.
Delta plus might reduce the efficacy of the vaccines currently in use. But we can’t be sure because we’re yet to see good data on this variant.
Two scientists claim that the genome pairing CGG-CGG is evidence that SARS-CoV-2 was made in a lab.
The research community is taking a closer look at the lab-leak hypothesis for the origin of COVID-19, prompting discussion about the risks and benefits of engineering viruses.
China has administered more than one billion doses of its homegrown COVID-19 vaccines, the majority of which were developed by local companies Sinovac and Sinopharm. So what do we know about them?
The Delta variant: What it is, where it came from, why it’s different and whether COVID-19 vaccines can prevent it.
Various companies use different ingredients and different delivery systems in their COVID-19 vaccines. Researchers are investigating whether it’s better for individuals to mix what’s available.
Health workers have long called for better protections against COVID-19. Well fitting masks are now required when caring for COVID-19 patients. But the guidelines on ventilation miss the mark.
People who contract COVID, and their contacts, have successfully self-isolated at home since the pandemic began.
