Sometimes negative spaces are interesting. In multiple ways. I noticed and then searched the article for the phrases "PTSD" and "survivor guilt" both of which I'd expect in a story about survivors of a scary epidemic, but didn't find them. Maybe just authors word choice. Maybe they hold legacy political meaning I don't know. Could be there's background I don't know why PTSD or survivors guilt uniquely wouldn't apply to this particular epidemic. But it was interesting in its absence. I could imagine a very smart author doing that word play intentionally to make someone think hard about his article.
