He stared at the figures sickly. Most of the village not only had the plague but must be near the end of the incubation period. It looked as if most of the village would be dead before another year passed.
"Bad?" Jake asked.
"The first symptom of Martian fever."
The old man whistled, the lines around his eyes tightening. "Must be me," he decided. "I'm the guy who must have brought it here, then. I used to spend a lot of time with Durwood at his diggings!"
There was a constant commotion all that day and the next as runners went out to the villages and came back with reports. The variation from village to village was only slight. Most of Mars seemed to have advanced cases of Martian fever.
Without animals for investigation and study, real research was difficult. Doc also needed an electron microscope. He was reasonably sure that the disease must travel through the nerves, but he had found no proof beyond the hard lump at the base of the neck. There it was a fair-sized organism. Elsewhere he could find nothing, until the black specks developed.
His eyes ached from trying to see more than was visible in the microscope. The tantalizing suggestions of filaments around the nuclei might be the form of plague that was contagious. They might even be the true form of the bug, with the bigger cell only a transition stage. There were a number of diseases that involved complicated changes in the organisms that caused them. But he couldn't be sure.
He finally buried his head in his hands, trying to do by pure thought what he couldn't do in any other way. And even there, he lacked training. He was a doctor, not a xenobiologist. Research training had been taboo in school, except for a favored few.
The reports continued to come in, confirming the danger. They seemed to have the worst plague on their hands in all human history; and nobody who could do anything about it even knew of it.
"Molly reports that your letter got some results," Jake reported. "Chris Ryan brought home one of the electron microscopes and a bunch of equipment from the hospital pathology room. Think she'll get anywhere?"
