I like this idea. This also seems easy to approximate in vitro. Pathogen growth rate at body temp vs pathogen growth rate at fever temp. Are they markedly different? When I have had a fever, it is not a significant absolute temperature change. Seems reasonable that the infection can handle it. It probably always needs to survive room temperate->human temps, so has mechanisms to cover a large gradient.
