The quicker viruses are produced, the greater the damage to the animal.”[5] Ironically, the attempt to suppress such outbreaks through mass culling—as in the recent cases of African swine fever which resulted in the loss of almost a quarter of the world’s pork supply—can have the unintended effect of increasing this selection pressure even more, thereby inducing the evolution of hyper-virulent strains. Though such outbreaks have historically occurred in domesticated species, often following periods of warfare or environmental catastrophe that place enhanced pressure on livestock populations, increases in the intensity and virulence of such diseases have undeniably followed the spread of capitalist production.
