Poor Ventilation in Schools

This is just a quick listing of research on how poorly ventilated most school buildings are. Ventilation is more important than ever in the COVID era, but we should have done better long ago for the sake of student health and learning. Here are some details. NOTE: some articles will address other venues, such asContinue reading “Poor Ventilation in Schools”

How To Reduce COVID Risk With Worship Teams

Singing and wind instruments are the most productive aerosol generating activities in church life and aerosols are the main method of transmitting an airborne virus. Large aerosol droplets at close range and small (long hang time) aerosol droplets in the air at long range. How much exposure to COVID-19 is the issue [1] and theContinue reading “How To Reduce COVID Risk With Worship Teams”

Shining the Light of Truth … on Your Blood?

What if I told you … that shining a laser on a blood sample could tell you whether or not your symptoms were due to a virus or a bacteria? What if this handheld biosensor could detect virus antibodies too? The simple fact that there is no need to send the test off and waitContinue reading “Shining the Light of Truth … on Your Blood?”

The Maze Runner Mask: Aerosol Death Cure

The purpose of this post is to take down the persistent misinformation that continues to spread about the efficacy of masks in preventing the spread of COVID-19, or for that matter, any respiratory virus. In other posts I provide scientific research-based support and explanations of how and why masks work in terms of how theyContinue reading “The Maze Runner Mask: Aerosol Death Cure”

YES … Cloth Masks Work Against ANY Virus

I have spent a fair amount of time here demonstrating that face masks are effective against COVID-19. I have based that claim on various studies and the flow dynamics of aerosols, or the Physics of it all. It is my opinion that said research and Physics are sufficient to warrant compliance with recommendations for universalContinue reading “YES … Cloth Masks Work Against ANY Virus”

Will Warmer Weather Wipe Out COVID?

What matter mosts, heat or humidity? The conundrum of warm versus cold weather can be untangled a bit if you consider humidity as a cofactor with heat. The short answer is that more aerosolized virus particles are in transit when it is arid and less aerosolized virus particles are in transit when it is humid.Continue reading “Will Warmer Weather Wipe Out COVID?”

COVID Risk Reduction

A systematic review and meta-analysis of how distance, masks, and eye protection reduce virus transmission was published in The Lancet on June 1, 2020. The scope of the review included 172 observational studies across 16 countries and six continents. There are three key findings involving over 25,000 participants in health-care and non-health-care settings. The AbsoluteContinue reading “COVID Risk Reduction”
