Medical News Today: Schools will need more than fresh air to stop COVID-19: MIT study

In the early days of the pandemic, researchers proposed that the main route of SARS-CoV-2 transmission was either via large droplets that people exhaled in a projectile motion through coughs and sneezes or via surface contamination. Recent work, however, has uncovered that virus particles can also infect others via long-range spread.

Behind this long-range spread are bioaerosolsTrusted Source, which are droplets or particles smaller than 5 micrometers. What makes them problematic in terms of risk exposure is that they can remain suspended in the air for extended periods and move with air currents.

Larger particles are of lesser concern in that aspect as they tend to sink to the ground and remain there.

The researchers behind a new study, which appears online in the journal Building and Environment, decided to explore this phenomenon further by applying it to classrooms to see whether having students and teachers present in the room would change the SARS-CoV-2 exposure risk.

A Protect Our Province BC panel discussion with A panel discussion about how we as a community can pull together to create a safer learning environment for kids when school starts again in September! We can avoid another ‘tripledemic’ if we work together! Ready for Fall 2023? video: Briefing video:
“COVID-19 vaccination is safe during pregnancy and may protect newborns from infection, especially if vaccines are given in the second or third trimester. This is similar to what we are already doing with other maternal vaccines, including TDaP and seasonal influenza.” – Dr. Eastabrook
“If we had an epidemic of people with broken limbs and we saw people in plasters and crutches, it would be more evident. But there is a lot of disability that is happening, which is a hidden disability often, which is why we need to talk about it more, for people to understand what the consequences are. And that will help to make better decisions.” - Lynette
