Hazleton's handover of the Reston monkey house to the U.S. Army

Hazleton’s handover of the Reston monkey house to the United States Army was the decisive institutional transfer that allowed a military team to take over a facility where an Ebola-like agent was spreading among monkeys. The move followed illness among two employees and a breakdown in confidence that the operation could safely continue under its existing management. It resolved who would control the building, but not the wider tension over which agency had the authority—and which would bear responsibility—for responding to the outbreak.

The crisis behind the transfer

At Hazleton Washington, Dan Dalgard faced the possibility that two employees had become ill in connection with the monkey facility. One had a heart condition; another had a fever and vomiting. Dalgard knew that such symptoms could have other causes, but he also understood that they might signal infection. The concern was no longer confined to the animals: the employees had gone about ordinary public and family life, and their possible exposure raised questions about people beyond the building.

Dalgard had previously believed that the absence of apparent human illness suggested there was little immediate risk. That confidence had lasted while the facility continued operating despite the presence of the disease. Now, with two workers sick and one being taken for medical care, he concluded that the situation had changed. He went to the general manager to seek approval to close the operation and turn the building over to the Army. As he explained what had happened, he began to cry; his breakdown marked the moment when accumulated pressure gave way to an explicit recommendation for evacuation.

The general manager agreed that the facility should be evacuated and shut down. When representatives of the Centers for Disease Control and Prevention arrived to begin surveillance of exposed employees, Dalgard told them that he wanted the building and the monkeys transferred to the United States Army Medical Research Institute of Infectious Diseases, whose personnel and equipment were suited to the work. The representatives did not oppose the proposal. Their presence also clarified that responsibility was divided: the Centers for Disease Control and Prevention was handling the human-health response, while control of the monkey house and its animals remained unsettled.

Authority and responsibility

The handover had been foreshadowed by a debate over what to do with the infected monkey population. One possibility was to isolate the animals and allow the outbreak to run its course; another was to kill the monkeys and disinfect the building. Neither option removed the need to protect workers and the surrounding public. Participants also recognized that the Army’s practical expertise did not match its formal jurisdiction. The Centers for Disease Control and Prevention had the federal mandate to control human disease, while the Army had specialized biohazard capability but no clear statutory responsibility for an outbreak on American soil.

Philip K. Russell identified this mismatch as a potential source of conflict between agencies. An Army response could prompt a dispute over institutional jurisdiction even as the virus continued spreading. He argued for rapid action and a chain of command, reasoning that legal questions should not prevent the response from being organized. The meeting assigned C. J. Peters to lead the operation and set in motion a broader effort to inform the relevant officials, including Frederick A. Murphy at the Centers for Disease Control and Prevention. The decision to proceed was therefore not simply a technical judgment: it was also a choice to act amid uncertainty about authority and procedure.

The conflict became concrete when Dalgard told Peters that a monkey caretaker was sick and offered to place the facility and animals under the Institute’s responsibility. Peters was wary of that formulation. Accepting responsibility could expose the Army to legal claims if the response failed and people died. He wanted control of the building, but did not want an ambiguous transfer to make the Army liable for the situation as a whole. At the same time, he was concerned that the sick employee was being taken to Fairfax Hospital rather than to the Institute’s high-containment unit. Dalgard and Peters thus confronted separate but connected questions: who would take over the contaminated site, and where should a potentially exposed worker receive care?

Negotiating the handover

Dalgard convened a call with Hazleton’s senior managers and reported that two employees were down, with the second potentially suffering from the same outbreak. The managers approved his decision to offer the monkey house to the Army, but wanted the agreement put in writing and the Army to accept legal responsibility after taking control. Peters rejected that demand. To him, adding a liability negotiation threatened to delay an urgent operational decision; he wanted clarity about control, not a prolonged exchange between lawyers.

Dalgard and Peters then agreed on a simpler written transfer. Dalgard faxed a letter conveying the monkey house to the Army, and Peters carried it by hand to Philip K. Russell. Russell and Peters reviewed the document and signed it without submitting it to Army lawyers first. Russell’s response treated the legal questions as something to address while pursuing what he considered the necessary course of action. The signed letter was faxed back to Dalgard, and the monkey house passed into Army hands.

The agreement resolved the immediate question of who would control the site, but it did not amount to an unqualified acceptance of every possible liability. The negotiations show the parties drawing a practical line: Hazleton would relinquish the facility, while the Army would take it over without first settling the broad liability terms its managers had requested. Speed and operational control prevailed over a fully negotiated allocation of legal responsibility.

From transfer to operation

The transfer made possible a larger Army response under Jerry Jaax, commander of the 91-Tangos at the Institute. His team would have to enter the monkey house and manage an operation involving a large number of animals. The soldiers were not an established field force for outbreaks of this kind; Jaax had not previously led his unit in combat, and the group had to prepare for work in protective suits under the pressure of a feared, potentially fatal infection. Hazleton’s decision therefore did more than change the name of the organization in charge: it placed the next phase of the response in the hands of a military team assembled for a task without an established precedent.

The handover also transferred the animals from a commercial research setting into an emergency containment operation. In preparation, Army personnel were told that they would be working with blood and sharp instruments and would wear disposable protective suits. The operation’s stated purpose was to stop the agent from spreading beyond the building, even though that meant the animals would be euthanized. That aim echoed the earlier disagreement over allowing the outbreak to continue within the facility or ending it through a more direct intervention.

The episode’s significance lies in the uneasy combination of urgency and institutional improvisation. A sick employee made continued operation untenable; Hazleton management agreed to relinquish the site; and the Army accepted control despite concerns about legal exposure and jurisdiction. The signed fax supplied a practical bridge between a private facility and a federal response, but not a tidy settlement of every question the outbreak raised. The monkey house changed hands because delay itself had become a risk.
