Note 67 — Chapter XIII · SPEKE IN UGANDA
Reading edition
According to the traditions of the natives, syphilis and smallpox entered Uganda about the same time, and came originally from Unyoro. Unyoro received these plagues from the first Nubian slave- and ivory-trading caravans, which were the pioneers of Egyptian rule in the forties of the last century. Syphilis and smallpox were also brought by the Zanzibar trading caravans from Unyamwezi not many years later.
