@verroq is correct though, but that is a different subject than the one of the article. (Infectious) diseases generally spread more easily in higher population density. That's basic epidemiology, more contacts = opportunities, but it's of course more complicated than one single statement, disease spread models need a lot more variables than just population density to make useful predictions. https://en.wikipedia.org/wiki/Threshold_host_density https://en.wikipedia.org/wiki/Threshold_host_density http://pai.org/wp-content/uploads/2012/02/PAI-1293-DISEASE_compressed.pdf http://pai.org/wp-content/uploads/2012/02/PAI-1293-DISEASE_c...

Well, it used to be that infant mortality was a lot bigger, some of which was probably infants dying to things they were exposed to. So we can't just ignore survivorship bias in considering these things. In general, we're probably better off with controlled, safe exposures (e.g. vaccines) than uncontrolled exposure and simply hoping we'll survive anything we catch.
