“And now,” it ended, “has anyone anything they would like to say about this report?”
There were a few things Hewlitt would have liked to say, but he knew the question was not directed at him. It was Pathologist Murchison who spoke first.
She said, “Even though the condition was atypical in that the symptoms appeared and receded with unusual rapidity, Telford’s diagnosis of what appeared to be a wide-ranging and nonspecific allergy was sensible in the circumstances, as was his decision not to attempt further medical treatment until he knew exactly what was going on. Essentially, that is what the patient’s medics did on Earth and later in Sector General. In a word, nothing …”
“Pathologist,” Naydrad broke in, its fur spiking with impatience. “You are restating the problem, not offering a solution.”
“Perhaps,” said Murchison, who knew her Kelgians well enough not to be irritated by the interruption. “But the point I’m trying to make is that the allergy symptoms appeared at a very early age and were repeated, with minor variations, here, on Earth, and in Sector General. This makes me wonder if the patient was born with the condition and we should be looking for a genetic rift of some kind. There are no recorded instances of anyone being allergic to the food produced by the synthesizers, which is the kind most off-planet visitors favor, and certainly not baby-formula varieties. And there would be no allergic response if … Hewlitt, were you breast-fed as an infant?”
“If I was,” he replied after a quick search of his earliest memories, “I was too young to remember.”
Murchison smiled. “Too bad, but it may not be important. If you were breast-fed and weaned onto synthesized food, that might explain why the first recorded allergic reaction was to medication. There is another possibility. The symptoms first appeared in the base hospital a few hours after the flyer crash. You were not hurt, but it is reasonable to assume that the fall through the branches onto the soft, wet ground rendered you temporarily unconscious. Certainly, your shocked and confused condition when found is symptomatic of a recent concussion. But it is possible that you sustained minor lacerations or abrasions, too minor in the circumstances for the rescuers to bother recording them, and that something was introduced into your system which caused the later allergic reaction. It might have been something living in the tree or on the ground, a spore or an insect or even a small animal that bit you, or a toxic substance with unknown properties that gained entry though a scratch from the foliage itself. I suggest a search of the crash site. If the suspect organism or material is native to Etla, it will still be there.
“And stop tying your fur in knots, Naydrad,” she went on. “I know that pathogens native to one world cannot affect any being who evolved on another. I also know that physiologically the natives of Etla and Earth are almost identical, so much so that there are theories about a prehistoric colonization program by common, star-traveling ancestors. But attempts at procreation between the few base personnel who, for emotional reasons, felt impelled to widen cultural contact by marrying Etlan men or women were unsuccessful. But if there is an overlap, no matter how small, in the gene structure of the two species, then that, too, should be investigated. And if Patient Hewlitt would submit to tests, very closely monitored and using trace quantities of Etlan native medication to minimize the risks, we might find the exception that proves the rule.”
“No tests, friend Murchison,” said Prilicla, before Hewlitt could say the same thing in stronger language. “No medication of any kind, Etlan or otherwise, until we have a clearer idea of what we are looking for. Perhaps you have forgotten that friend Hewlitt has already been affected by Etlan native vegetation, when it ingested toxic fruit prior to falling from a tree?”
“I have not forgotten,” said Murchison, “that the younger Hewlitt survived two falls without injury. That was very fortuitous and it may also be significant if we assume that something in the fruit he consumed before the first fall caused the hyperallergic reaction following the flyer accident. The record of events during and after the second fall are supported by objective clinical evidence, but the circumstances surrounding the first is subjective, uncertain, and supported only by childhood memories that may prove to be untrustworthy. For example.
