We're used to the idea that we halt epidemics by treating people who are infected and vaccinating everyone else. But what if there is no treatment and no vaccine? Pretty scary huh?
Then we'd have to resort to civic measures. So it's nice to see this account of how well a civic measure worked to contain the spread of H7N9 influenza. Some specifics helped - it seems the virus spreads from poultry to man but not much from person to person.
It reminded me of a paper I blogged about five years ago which assessed the effect of school closures in the 1918 pandemic.
