The Hate Disease (1963) is a science fiction short story about the interplanetary medical service, by Murray Leinster. Excerpt from the book: "The Med Service people hit strange problems as routine: if they weren't weirdos, they weren't tough enough to merit Med Service attention. Now the essence of a weird problem is that it involves a factor nobody ever thought of before ... or the absence of one nobody ever missed ... The Med Ship Esclipus Twenty rode in overdrive while her ship's company drank coffee. Calhoun sipped at a full cup of strong brew, while Murgatroyd the tormal drank from the tiny mug suited to his small, furry paws. His purpose was a routine checkup on public health on Tallien Three. Calhoun had lately completed five such planetary visits, with from one to three weeks of overdrive travel between each pair. When he left Tallien Three he'd head back to Sector Headquarters for more orders about the work of the Interstellar Medical Service."
