Most kids will be unvaccinated if schools in the two largest states re-open in term 4. There may still be community transmission, but there are measures we can take to shield kids from the virus.
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.
With evidence showing the COVID virus is airborne, it’s no coincidence many outbreaks in schools have occurred in winter – when windows are closed.
We found two small air cleaners in a single hospital room could clear 99% of potentially infectious COVID aerosols within 5.5 minutes.
Toronto Public Health’s tool kit for COVID-19 prevention in congregate living settings contains few references to ventilation, air filtration and other measures to prevent airborne transmission.

Because COVID-19 is airborne, we can’t know if the shelter system is as safe as it should be without seeing metrics related to ventilation, filtration and occupancy.
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.
Surface transmission is a very uncommon way of getting COVID. We should focus most of our attention on the airborne route, potentially saving millions of dollars on obsessive cleaning practices.
Researchers are working on handheld devices that can signal the presence of SARS-CoV-2 in the air.

Miniaturized laboratory equipment is making it easier to identify airborne pathogens in the field, but there’s still work ahead to be able to instantly determine if a room is safe or contaminated.
Coughing, sneezing, talking and even just breathing can produce airborne particles that can spread SARS-CoV-2.

SARS-CoV-2 can be spread through the air. But just how much of a factor that is has been hard to determine. Recent evidence suggests it is common, posing problems as public places begin to reopen.
Retailers are selling ‘anti-virus masks’ but there is no strong evidence that they can stop the spread of flu.
A new reactor may soon be able to safely disinfect the air in crowded spaces.
Ebola is not spread through small airborne particles or larger droplets from coughing or sneezing.
Suggestions the Ebola virus could “mutate” into a form that is transmissible by the respiratory route are speculative, and the likelihood of it happening are low. Nonetheless, the idea appears to have…
