I thought the metaphor was clear - society, as a whole, is not threatened by this sort of thing, and it is not even particularly dangerous from an expected value perspective. The point is not that nothing should be done - as I mentioned with my reference to hygiene precautions. Washing your hands and encasing yourself in an antiseptic bubble are two
very different things, and the fact of the matter is that
not all deaths are preventable. I was trying to make the point that the knee-jerk reaction of "something should be done" discounts the possibility that sometimes it's not worth it to do anything, either because additional action would have no effect or because the marginal cost of that action exceeds the benefits.
A fairly large number of people die from influenza every year, but we don't have a mass surveillance dragnet to try and isolate flu vectors, for good reason. We do, however, have a fairly robust vaccination system which is a sensible precaution to take.
