condition for as long as possible. It transferred when, in spite of its efforts, a host grew too old or was killed by a larger predator, whereupon the predator became the new host.
A great many centuries must have elapsed before the highly intelligent and extremely long-lived explorer Lonvellin visited its home world and, believing that no off-world pathogen could affect it, took no precautions and acquired a most unusual and unique parasite.
Instinctively the virus realized that it had found an organism that could be made to survive for a very long time indeed, but the new host’s body was so massive and strange and complex that it had extreme difficulty adapting to the new surroundings. Lonvellin, however, who must have been subject to many irritating and uncomfortable illnesses during its long life, would have deduced the virus’s presence and capabilities from the fact that the incidence of its former maladies was dropping toward zero. But at that time the virus creature could not communicate with its host, nor was it aware of the reasons why certain obscure metabolic processes were taking place in that massive and confusing body. All it was able to do at the time, and then only with great difficulty, was to maintain its host in the same physiological condition as it had been in when found.
The virus made mistakes.
One of them, its stubborn retention of dying skin material which would normally have been discarded and replaced with new growth, brought Lonvellin to Sector General. Another was allowing the then Senior Physician Conway to trick it into leaving its host and revealing itself as a separate entity. At this stage in its continuing evolutionary development the virus creature was sapient but not very bright.
After it was reclaimed by Lonvellin, it traveled to Etla, where it had a narrow escape from the nuclear detonation that killed its host. That incident came close to killing the creature as well, but instead resulted in a structural mutation which later enabled it to enter and adapt to a radiation-eating Telfi host.
It saved the Hewlitt child’s life twice, after the poisoning and potentially lethal fall from a tree and following the flyer crash, but it was still making mistakes, such as halting the blood circulation by arresting the heart so as to give it more time to negate the effect of any fast-acting foreign medication introduced, which eventually resulted in the adult Hewlitt being sent to Sector General. It was learning, however, and becoming increasingly aware of the host’s mind and feelings as well as its own. The process began with Lonvellin, but the incident with the mutilated cat was more important than was realized because it was the first time that the virus had been influenced by psychological factors, specifically the emotional pressure of a child’s grief for a dying pet, into changing hosts.
“The transfer was temporary,” Hewlitt went on, “because it was not in the creature’s interests to move from a long-lived host to a small and shorter-lived one. By then it was being driven by curiosity and the urge to experiment as well as by its need to survive into the indefinite future, but for a long time there were only Earthhumans like myself available and it had not yet fully understood the workings of my body. By the time I arrived here it was becoming intensely curious, more aware of its surroundings and hungry for the new experiences that were available in a place that is filled with very interesting and long-lived potential hosts. When it felt my sorrow and sympathy for Patient Morredeth and I accidentally touched, or perhaps was subtly influenced by it to place a bare hand on, the wound where the fur had been destroyed, it transferred to its first Kelgian. Later it moved to the Padre and then to Cherxic and, in turn, to each of the surviving members of the Telfi ship gestalt, where the latest and most significant but not, it believes, the final adaptation occurred. From the telepathic and technically highly specialized members of the ship gestalt it learned how to communicate mind-to-mind with its subsequent hosts, and to understand and control at the particle level the radiation on which the Telfi live. The covert and Telfi-guided experiments with the hospital’s power system were part of its learning process.
“Now it has everything it needs to survive into the indefinite future,” Hewlitt went on. “Individual Telfi will die, many with less frequency now that it is moving among them, but the gestalts replace or increase their membership and will continue to amass information and experience. It has found the perfect host species. With the willing cooperation and the radiation-absorption mechanism of the Telfi as its launching point, it will grow in size and intelligence and power, and it will continue to evolve until it is able to populate the stars or, a risk which it fully accepts, kill itself in the attempt.
“The hospital will not be troubled with the virus creature again.”
In his earpiece there was a long, hissing silence that was broken by a voice that was so quiet and distorted with emotion that it could have belonged to anyone.
“So it intends to infect and populate the stars,” it said. “I don’t doubt that it means what it says, because we already know that it is impossible to lie with the mind. That could lead to the breakdown of the Federation, perhaps the end of free and unprotected otherspecies contact, perhaps of all intelligent life because of an uncontrollable, interspecies contagion sweeping the member worlds, if we don’t act at once. We’re sorry, Hewlitt, but that action must include isolating Lioren, Morredeth, the Telfi ship’s crew, yourself, and even your childhood pet from all future contact for the rest of your lives.”
“No!” said Hewlitt angrily. “Why don’t you people listen to me, or believe me when you do listen? Padre, will you explain it to them, please?”
While the voice from O’Mara’s office had been speaking, the Padre had closed the Telfi caskets and returned its attention to Hewlitt. He had the feeling that Lioren’s emotional distress had eased or was at least under control again.
“I couldn’t explain it any better myself,” said the Padre. “Carry on, but be quick. Our covered litters and, dear me, an armed escort are arriving.”
Hewlitt took a deep breath and chose words that were short and simple. He said, “O’Mara, all of you are wrong, twice. None of the virus creature’s hosts are infected, or contagious, nor have we been implanted with its seed or embryo. It doesn’t work like that. The creature is an intelligent, organized collection of viruses, a single and very selfish individual who will not willingly allow parts of itself to be detached and thereby reduce the capability and intelligence of the whole. My problems during and after puberty were caused by the fact that, while it could understand the need of a host to eliminate body wastes, the expulsion of healthy living material like seminal fluid was totally foreign to it because, at that time, it could not conceive of the possibility of any entity wanting to propagate its kind rather than surviving for itself alone. It still has difficulty accepting the idea of countless billions of us sacrificing ourselves so that our various species will survive.
“On Etla, on Earth, and in the hospital,” he went on, “there was absolutely no risk of secondary infection. Perhaps in the future, if its plans work out, it may be able to divide itself, but that time is a very long way off and even then we would be in no danger from it. For now the virus can occupy only one entity at a time, and it does not leave its host with a disease but with a level of physical, lifelong health that is immediately obvious as a kind of organic artist’s signature to all of its former hosts.
“It does this out of gratitude,” Hewlitt went on, “for the knowledge and experience provided by the host. It considers itself a tenant who is obliged to pay rent.”
The litters, their canopies open and ready, were accompanied by two massive Hudlar medics and eight armed Monitor Corpsmen who were large by Earth-human standards. The men’s expressions showed a mixture of embarrassment and determination. Hewlitt spoke quickly.
“Believe me,” he said, “neither the Federation nor its citizens have anything to fear from the virus creature. It is no longer interested in the extremely short-lived natives of any planet. Even though the project will take many of our lifetimes to complete, its ambition is to populate the stars one at a time and beginning with the Telfi’s parent sun, which, in astronomical terms, is growing old and sick. While there is always the chance that it will obliterate itself in the attempt, it considers the risk well worth taking. To inhabit a sun that can be inhabited and given intelligence, stability, and control of all its internal processes is the virus creature’s ultimate goal.
“An intelligent star,” he ended, “would be the most long-lived entity there could ever be.”
This time it was Diagnostician Conway, Prilicla, and Thornnastor who were doing most of the talking while the litter personnel and escort waited for them to decide what they were going to do. For several minutes it seemed that the Padre and himself had been forgotten as they debated the possibility of retracing Lonvelun’s travels before its arrival in Sector General with a view to finding the virus creature’s planet of origin and other, perhaps nonsapient members of its species who could be studied and, hopefully, helped to proliferate. If it was offered, the assistance of former virus-creature hosts would be invaluable. All necessary precautions would be taken and there would be many problems to overcome, but if they were successful they could foresee a distant future when the citizens of the Galactic Federation would carry only one virus and be otherwise completely disease-free. All that would be left for the medical profession would be the treatment of accident and surgical emergencies. It was the chief psychologist who had the last, impatient words.
