Richard Preston Quote

When I rode along the Kinshasa Highway as a boy, it was a dusty, unpaved thread that wandered through the Rift Valley toward Lake Victoria, carrying not much traffic. It was a gravel road engraved with washboard bumps and broken by occasional pitlike ruts that could crack the frame of a Land Rover. As you drove along it, you would see in the distance a plume of dust growing larger, coming toward you: an automobile. You would move to the shoulder and slow down, and as the car approached, you would place both hands upon the windshield to keep it from shattering if a pebble thrown up by the passing car hit the glass. The car would thunder past, leaving you blinded in yellow fog. Now the road was paved and had a stripe painted down the center, and it carried a continual flow of vehicles. The overlanders were mixed up with pickup trucks and vans jammed with people, and the road reeked of diesel smoke. The paving of the Kinshasa Highway affected every person on earth, and turned out to be one of the most important events of the twentieth century. It has already cost at least ten million lives, with the likelihood that the ultimate number of human casualties will vastly exceed the deaths in the Second World War. In effect, I had witnessed a crucial event in the emergence of AIDS, the transformation of a thread of dirt into a ribbon of tar.
