My op-ed entitled “Travel bans can’t stop this pandemic” was published in The Hill. You can read it here.
An air #travelban isn't an effective way to stop #coronavirus transmission, @uwisye's @lauraalbertphd writes on @thehill.https://t.co/cutS5bJpAh#COVID19

The US airport situation is not being managed well.

Screening everyone very thoroughly only works if there are adequate resources to do the screening.
There aren't. And now there are long lines.https://t.co/iQnW16XuVa
This is extra dangerous in a pandemic when those waiting in line for #COVID19 screening get infected while waiting.

Instead of one infected traveler entering the US, you now have 10.
Allocating enough resources is critical.

Without enough resources, more infected travelers will enter the US by implementing under-funded screening methods aimed at keeping the infected travelers out, reversing the intended effect of the screening policies.
A better approach: do less screening, focusing resources on the riskiest travelers. For others, quickly collect information about travelers and disseminate information and keep the lines moving.

A key approach to controlling a pandemic is to lower R_0. Limiting the number of people (and time) people are near each other clearly lowers R_0. It follows that crowded airport wait lines and long flights hurt R_0. Given early signs of overtaxed medical resources in parts of the world I would argue that the costs justify the benefits.
The structural difference between terrorrist attacts and pandemics is that the latter is a multiplicative process: it is nearly inconceivable that the number of attacks could increase by a factor of 200 in month (a daily 20% growth rate) but not for a pandemic.
