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.
Masking indoors will yet again be the new normal in Los Angeles County – and possibly elsewhere in the U.S.

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.
As coronavirus cases surge, unvaccinated people are accounting for nearly all hospitalizations and deaths.

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.
The Lambda variant accounts for almost all new cases in Peru, which has the world’s highest COVID death toll per capita.

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.
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.
Security precautions, thoughtful facilities design, careful training and safe lab practices help keep pathogens isolated.

Two scientists claim that the genome pairing CGG-CGG is evidence that SARS-CoV-2 was made in a lab.
In February 2021, a World Health Organization team investigating the origins of COVID-19 visited the Wuhan Institute of Virology in Wuhan, China.

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 emergence of variants of concern in late 2020 marked a shift in the COVID-19 pandemic.

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.
