Will the Mandaters Apologize?

 

Not Following the Science

 A dozen scientists from around the world conducted a massive metastudy of our efforts to fight COVID, as well as similar efforts to fight the flu, and they published the results in the Cochrane Database of Systematic Reviews.

The authors examined 78 different studies on the efficacy of different mitigation efforts such as masking, distancing, screening, quarantining, and hand-washing. How did these interventions affect the spread of the flu, COVID, or similar viruses?

The studies included were diverse. They covered epidemics as well as periods of low transmission. They covered rich countries and poor countries, suburban schools and inner-city neighborhoods, hospitals and villages.

Most important was what they had in common: They were all randomized controlled trials or at least cluster-RCTs. These are the gold standard for studies because they have the greatest chance of avoiding confounding factors. Non-randomized, non-controlled trials — for example, observational studies — can be compromised if, say, people become more likely to wear masks at times or places that already have higher rates of spread, or if people who wore masks were also more fastidious hand-washers.

So, what did the studies find?

For starters, hand-washing was effective in stopping the spread of these illnesses. That’s not surprising.

But here’s the most eye-opening finding: “Wearing masks in the community probably makes little or no difference to the outcome of influenza‐like illness/COVID‐19-like illness compared to not wearing masks.” In other words, masks didn't do much — if anything.
