Six months after the outbreak, who’s investigating the CAFO-swine flu link? | Grist: "When respiratory viruses get into these confinement facilities, they have continual opportunity to replicate, mutate, reassort, and recombine into novel strains ... The best surrogates we can find in the human population are prisons, military bases, ships, or schools. But respiratory viruses can run quickly through these [human] populations and then burn out, whereas in CAFOs—which often have continual introductions of [unexposed] animals—there’s a much greater potential for the viruses to spread and become endemic.”
—Gregory Gray, director of the Center for Emerging Infectious Diseases at the University of Iowa College of Public Health, quoted in “Swine CAFOs & Novel H1N1 Viruses,” Environmental Health Perspectives, September 2009, by Charles W. Schmidt."
