    Hello TWIVers,

    My question is general and not specific to any episode or discussion that I remember.

    I have always thought that fevers were an integral part of a body’s attempt to resolve an infection, at least a relatively sever infection. It seems unlikely that temperature affects pathogens negatively given that many viruses (including SarsCov-2) and bacteria infect a wide range of animals. What role does fever play?

    Thanks. I appreciate everything you folks do.
