What was Silverstein's response to finding out about the Marburg diagnosis

Suspecting that Dr. Musoke is suffering from an unknown virus, Dr. Silverstein collects a sample of his patient’s blood serum and sends it to be tested at the National Institute of Virology in South Africa and the Centers for Disease Control in the United States.

Dr. Silverstein soon receives word from South Africa that the blood sample is positive for Marburg, an African virus that was first identified at a vaccine factory in Marburg, Germany in 1967. After an initial outbreak in a shipment of monkeys that arrived at the factory, the virus soon spread to the human population, killing one in four of those infected. It was later discovered that the infected monkeys had undergone only a basic visual inspection prior to being exported.

Based on this new information, Dr. Silverstein convinces the Nairobi health authorities to shut down the hospital and quarantine the 67 medical staff members who had interacted with either Monet or Musoke. However, none of the staff members develop the virus. After ten days of illness, Dr. Musoke begins the slow but steady process of recovery. Although he retains no memory of his time under the influence of the Marburg virus, samples of Musoke's blood are sent to laboratories across the world
