My Cornell colleague and leading constitutional law scholar, Mike Dorf, has an interesting and provocative post (here) that speaks to the array (and growing number) of state quarantine measures responding to the Ebola crisis.
The ELS angle, of course, is Mike's point (drawn from CDC data) that: "the log(viral load) just before symptoms develop is 4.6. A day later, the log(viral load) is 7.2. Thus, (assuming linearity to first order) 12 hours after symptoms develop, the log(viral load) is 5.8. That's a change of 1.2 in log(viral load), meaning that the change in viral load more than triples (because e to the 1.2 power is 3.32.)."
