Masking: A Careful Review of the Evidence

Authors:

Paul E. Alexander – February 11, 2021

The question on whether to wear a face mask or not during the Covid-19 pandemic remains emotional and contentious. Why? This question about the utility of face coverings (which has taken on a talisman-like life) is now overwrought with steep politicization regardless of political affiliation (e.g. republican or liberal/democrat). 

Importantly, the evidence just is and was not there to support mask use for asymptomatic people to stop viral spread during a pandemic. While the evidence may seem conflicted, the evidence (including the peer-reviewed evidence) actually does not support its use and leans heavily toward masks having no significant impact in stopping spread of the Covid virus. 

In fact, it is not unreasonable at this time to conclude that surgical and cloth masks, used as they currently are, have absolutely no impact on controlling the transmission of Covid-19 virus, and current evidence implies that face masks can be actually harmful. All this to say and as so comprehensively documented by Dr. Roger W. Koops in a recent American Institute of Economic Research (AIER) publication, there is no clear scientific evidence that masks (surgical or cloth) work to mitigate risk to the wearer or to those coming into contact with the wearer, as they are currently worn in everyday life and specifically as we refer to Covid-19. 

We present the evidence in full below. We also state that should adequate evidence emerge that supports the effectiveness of surgical and cloth masks in this Covid pandemic (or any similar type masks), then we will change our position and conclude otherwise. Our focus is on face masks for  Covid but we will touch gently on the issue of school closures and lockdowns, as these three issues remain the key public health policy catastrophes we have faced as global societies.
