Correcting the Math on Covid


For me, one of the most frustrating aspects of aggregating media coverage of the pandemic has long been the poor understanding and interpreting of statistical data by journalists, politicians and certain policy makers.


Over and over, stories appear in major media outlets based on incomplete data or misinterpretations of what is actually happening with Covid-19.

This in itself would be bad enough, but unwise public health policies are resulting in some areas, especially with regard to children and schools.

A prime example is the absolutely terrible idea of mandating vaccines for school-aged children -- a concept gaining ground in some areas but utterly unsupported by a rigorous analysis of the available data.

Fortunately, three mathematically-literate writers -- Leslie Bienen, Eric Happel, and Tracy Beth HΓΈeg -- have just published an excellent article called "How to Fix Our Broken Relationship With COVID Math" in the journal Persuasion.com.

Here are a few of their observations:

 (Q)uarantine policies have removed thousands of “exposed” children and staff from school, even though very few—63 out of 30,000 quarantined, in recent data from Los Angeles United School District—subsequently tested positive. This is not a good way to balance harms and benefits.

Specific demographic factors such as race and ethnicity, obesity, diabetes, and other co-morbidities make an enormous difference in determining risk of a bad COVID-19 outcome. But the single most important risk factor, age, is often relegated to a few short lines in too much news coverage. Downplaying the huge decreased risk of mortality in children compared with mortality risk in the elderly is simply not factual reporting.

The actual risk of COVID-19 hospitalization for a child under 18 who has COVID-19 is less than 0.2% per infection, or less than 1% per diagnosed case by current estimates; but it is 23% for an adult 65 or older, and even higher for those over 65 with co-morbidities. 

We often read that cases in children now make up over 20% of new infections. But news outlets often fail to point out that, as vaccination rates climb in older age groups and new infections fall in those groups, new cases in children will logically make up a greater proportion of all new infections.

* The data indicate that Delta is not significantly more harmful to children than previous variants.

Road accidents and drowning kill many more children between 4 and 14 than COVID-19, yet we still let them get in cars and go to pools. Another example is that children are around 20 times more likely to contract COVID outside of school than in school. The media need to put COVID-19 numbers into perspective instead of quoting a stand-alone number that readers cannot adequately assess compared to other risks they are willing to accept.

 Depression, obesity, eating disorders, opioid overdoses, and suicidality have all gone up markedly during the pandemic. The CDC’s own research showed recently that children who were already struggling with weight gain more than doubled their weight increase during the pandemic. The report pointed to school and sports closures as an important cause. This is one of many tragic consequences of our failure to take into account all harms, not just those caused by COVID-19, during this pandemic.

Since May, when the Delta variant spread worldwide, much attention has been paid to the question of whether vaccines work against this new variant as well as they did against earlier variants. The data show that vaccine protection has certainly decreased, at least against mild or asymptomatic infection. But the degree to which vaccines still offer protection to the general population from severe disease requiring hospitalization is being underestimated.

The fact that the vast majority of children have multiple greater threats to their health and well-being than COVID-19, and that those threats to health worsened as we tried to shelter children from any risk of COVID, should have been quickly integrated into our public health plans. Instead, school and sports closure policies in many cases aggravated these threats, while failing to have any major impact on controlling COVID-19 spread. The fact that vaccines are incredibly effective—way more so than is often reported—at preventing hospitalizations and severe disease should have been constantly and consistently emphasized and re-emphasized.

The problem of inadequate and inaccessible local data could be remedied relatively easily. Every state should promptly release hospitalization and mortality data—the two most important outcomes when it comes to COVID-19—in the form of simple tables and graphs. These should be stratified by vaccination status, age, race and ethnicity, local employment categories, and important co-morbidities such as obesity, diabetes status, and heart disease.
