Worobey said that the HIV epidemic that resulted from the turn-of-the-century spread correlates to the urbanization of colonial Africa, principally the present-day city of Kinshasa in the Democratic Republic of the Congo.
The growth of cities and associated high-risk behaviors may have been a principal cause of the rapid spread of the virus.

Worobey is optimistic about the eventual extinction of the HIV virus.
"I think the picture that has emerged here, where changes the human population experienced may have opened the door to the spread of HIV, is a good reminder that we can make changes now that could help reverse the epidemic. If HIV has one weak spot, it is that it is a relatively poorly transmitted virus. From better testing and prevention, to wider use of the antiretroviral drug therapy, there are a number of ways to reduce transmission and force this virus back into extinction," he said.
