what he had and that that was why she needed the samples, he finally gave in.
As for the monkey, Marissa didn’t even attempt to get a blood sample. The animal keeper was out for the day, and she had no intention of trying to handle the animal alone. The monkey looked healthy enough, but was not friendly. He threw feces at Marissa through the mesh of his cage.
Once Marissa completed the packing, making certain that all the screw caps were tightly in place so that carbon dioxide from the dry ice could not penetrate the samples, she personally rode out to the airport and sent the boxes on their way to Atlanta. Luckily she got them on a convenient nonstop.
Back at the Richter Clinic, Marissa made a detour to the small clinic library. There were a few standard texts there that included sections on viral diseases. She quickly scanned the entries for Lassa Fever, Marburg and Ebola virus. Then she understood Dubchek’s excited reaction on the telephone. These were the most deadly viruses known to man.
Arriving back on the fifth floor, Marissa found that all eight patients had been isolated in a separate wing. She also found that the clinic outpatient records she’d ordered had arrived. After putting in a call for Dr. Navarre, Marissa sat down and began to study the charts.
The first belonged to Harold Stevens, the real estate broker. She started from the back and immediately discovered that the last outpatient entry was a visit to Dr. Richter: Harold Stevens had chronic open-angle glaucoma and saw Dr. Richter on a regular basis. His last checkup had been on January 15, four days before he was admitted to the hospital.
With a sense of growing certainty Marissa looked at the last entry on each chart. There it was. Each patient had seen Dr. Richter on either the fifteenth or the sixteenth of January. All except Helen Townsend, the secretary from medical records, and Alan, the lab tech. The last entry in Ms. Townsend’s outpatient file recorded a visit to an OB-CYN man for cystitis. Alan had seen an orthopod the previous year for a sprained ankle he’d suffered in a hospital basketball league. Except for the medical secretary and the lab tech, there was the strong suggestion that Dr. Richter was the source of the illness. The fact that he’d seen five of the patients just before he developed symptoms had to be significant.
Marissa could explain the lab tech getting the illness by his sticking himself with a contaminated needle, but she couldn’t immediately explain Helen Townsend. Marissa had to assume that Helen had seen Dr. Richter sometime earlier in the week. She had come down with the illness just forty-eight hours after the doctor. Maybe he had spent a lot of time in medical records earlier that week.
Marissa’s musings were interrupted by the ward clerk, who said that Dr. Navarre had called to ask if Marissa would kindly come down to the hospital conference room.
Returning to the room where she’d started the day reminded Marissa of how long she’d been working. She felt bone weary as Dr. Navarre closed the door and introduced the other person who was present. He was William Richter, Dr. Richter’s brother.
“I wanted to thank you personally for being here,” said William. Although he was impeccably dressed in a pin-striped suit, his haggard face was mute testimony to his lack of sleep. “Dr. Navarre has told me your tentative diagnosis. I want to assure you that we will support your effort to contain this illness to the limits of our resources. But we are also concerned about the negative impact the situation could have on our clinic. I hope that you agree that no publicity would be the best publicity.”
Marissa felt mildly outraged, when so many lives were at stake, but Dubchek himself had said essentially the same thing.
“I understand your concern,” she said, uncomfortably aware that she had already spoken to a reporter. “But I think we have to initiate further quarantine measures.” Marissa went on to explain that they would have to separate the possible contacts into primary and secondary contacts. Primary contacts would be those people who had spoken with or touched one of the current eight patients. Secondary contacts would be anyone who had had contact with a primary contact.
