"It must have been about midnight, I was working below. I heard a rather strange noise up in the passengers' section and went up to find out what was going on. I found Mr. Hughes coughing and sneezing in the passageway, obviously in distress. I inspected him as best as I knew how and we got out my Medicology and compared symptoms. I'll read this section:
"'Coryosis, one of the nine allied infections which are frequently grouped under the ambiguous term "Common Cold," is extremely contagious but fatal only in cases of extreme sensitivity. Treatments consist of isolation amounting to a formal quarantine, and frequent injections of MacDonaldson's Formula 2, Ph-D3; Ra7. The patient is to be kept warm at all times and must remain quiet.'
"So we went to his cabin and I slipped him a shot and he went to bed. Now I'll read a bit more:
"'Contagion measures: Since the source of infection is a filterable virus, care must be taken to remain outside of the twenty-foot range of water droplets resulting from a cough or sneeze. All things touched by the patient must be either sterilized or burned. It is suggested that only one person tend the patient and that this person be immunized with MacDonaldson's Formula at regular intervals. Visiting should be discouraged, and if necessary must be carried on at a distance and for a very few minutes only. The incubation period is very short; the duration of coryosis is approximately fourteen days. It is, however, possible for a re-infection to take place which often resembles the initial infection, thus giving rise to the six-week cold.'

Professor Martin's face was grave. "What must we do?" he asked anxiously.
"Nothing," said Farradyne firmly.
"But he shouldn't stay on Pluto."
"That is correct. Pluto is very cold, even with the Terra conversion program going on. Mr. Hughes should be returned to Terra."
"But—"
