Zika virus is first isolated from a sentinel rhesus monkey placed in a cage on a tree platform in the Zika Forest near Lake Victoria, Uganda. The monkey, Rhesus 766, was part of the Rockefeller Foundation’s program for research on jungle yellow fever. Two days later, Rhesus 766, still febrile, was brought to the Foundation’s laboratory at Entebbe and its serum was inoculated into mice. After 10 days all mice that were inoculated intracerebrally were sick, and a filterable transmissible agent, later named Zika virus, was isolated from the mouse brains.
A second isolation of the virus from the mosquito Aedes africanus is confirmed in Uganda, at the previous site.
Heads of state of Tanzania, Uganda and Kenya, plus South African President Zuma meet in Tanzania to discuss a political crisis in Burundi triggered by the president’s plan to run for a third term. Nkurunziza doesn’t attend, and is represented by the country’s foreign minister, Aime. Rwanda also sends a minister rather than the head of state. The leaders call for the postponement of elections by at least a month and a half. Tanzania’s President Kikwete:
The leaders have been trying to navigate our way so we can help the people of Burundi to land safely under the current circumstances.
