HIV in Africa
Where exactly on the African continent did HIV begin to spread easily between humans? This is a question that scientists have debated over for some time. A new study has managed to trace the origins of HIV to Kinshasa, now the capital of the Democratic Republic of Congo, in the early 1920s. The scientists were also able to shed some light on how the disease spread with their research suggesting that it moved quickly through transportation networks that sprawled out of Kinshasa when it became a booming town for trade and the capital in 1923. Professor Oliver Pybus from the University of Oxford in the UK and Professor Philippe Lemey from the University of Leuven in Belgium explain how their team reconstructed the early history of HIV.
