Entebbe is the Ugandan setting for a consequential link in the primate trade: a monkey-export facility that sent an infected shipment onward to Europe. The book connects the town not only to the 1967 Marburg outbreak but also to a less visible network of wild-animal capture and transport around Lake Victoria, while stressing that the precise source of infection remained unknown.

Setting and connections

The export facility in Entebbe was run by a monkey trader whose business moved large numbers of animals abroad. The town also stood close to the Sese Islands, a forested archipelago in Lake Victoria that was an easy boat ride away. In the account given years later by the inspector Mr. Jones, the trader bought monkeys from island villagers, who regarded them as pests and welcomed payment for removing them.

The book places this trade within a wider regional setting. Uganda was among the major sources of primates for research, while the shores and islands of Lake Victoria connected villages, animal trappers, traders, and export routes. The particular island where suspect monkeys were released is never identified; Mr. Jones only recalled that it was near Entebbe.

The export facility and the 1967 shipment

In 1967, while the regular veterinary inspector was on leave, Mr. Jones temporarily inspected monkeys at the Entebbe export facility. The operation exported about 13,000 monkeys a year. Inspection was visual: he removed animals that looked sick or injured, and the remaining monkeys were cleared for shipment. The infected group traveled overnight to London and then on to Germany, where the outbreak began.

Mr. Jones later said that he had signed the export certificate and felt responsible for the deaths that followed. The account makes clear, however, that the virus was unknown to science and that a few animals without visible signs of illness could have carried it. His inspection could not have revealed an infection that had no apparent outward signs.

Suspect animals and an untraced route

Mr. Jones initially believed that sick-looking monkeys removed from shipments were being killed. He later learned that the trader had them boxed and sent to a small island in Lake Victoria, where they were released. When the trader needed more animals, he sometimes went back to the island to catch them. Mr. Jones considered it possible that Marburg had circulated among monkeys there and that some animals eventually sent to Germany had come from that source, but the island’s identity and the route of the infected shipment were not established.

The account also describes how the trader obtained wild monkeys from the Sese Islands through deals with local villagers. This raises the possibility that the nearby island used for releases was part of a wider circuit of capture and redistribution, but the book presents that connection as a reconstruction, not a proven chain of transmission.

Investigation and significance

After the outbreak in Germany, a World Health Organization team went to Uganda to investigate the monkeys’ source but did not speak with Mr. Jones, who had worked at the export facility. He said he had been told by his employer not to volunteer information unless asked. The team’s failure to interview the inspector left important details about the animals’ handling and possible island source outside the investigation.

Entebbe’s significance lies in this overlap of commerce, incomplete inspection, and unresolved epidemiology. The facility connected wild-caught animals to distant laboratories, while the account of released monkeys suggests another possible route by which infection could have persisted or circulated. The book also places the primate trade beside broader questions about viruses emerging from contact between people and animals, but it does not establish that the events around Entebbe caused AIDS or prove where Marburg’s natural reservoir lay.
