HIV pandemic started in Kinshasa, study says
October 3 , 2014
Rapid urban change in Kinshasa in the 1920s led to the HIV pandemic, scientists have said.
The virus is believed to have crossed over from chimpanzees to humans in Cameroon earlier, but it is in Kinshasa city, in the African Congo region, that it turned into the pandemic HIV strain and spread over the next 40 years, according to the study published in Science.
Kinshasa was rapidly expanding at the time, with the railway network carrying thousands of laborers to and from the city every week.
