AIDS Pandemic Provokes Alarming Reassessments Of Infectious Disease
Joshua Lederberg | Jul 11, 1993 | 5 min read
In 1900, infectious disease was the leading cause of mortality in the United States, accounting for at least 37 percent of deaths. By 1950, this had been mitigated to 6.8 percent and, by 1989, to 2.8 percent, with corresponding improvements in life expectancy. These numbers, of course, must be taken with a grain of salt, given the eventual preemptive role of infection in chronic illness, and many disorders whose infectious etiology is still to be recognized. Further, the relative importance

Stopping Ebola in Its Tracks Richard Preston brought the threat of emerging infectious diseases to the consciousness of his readers in The Hot Zone. The book graphically describes how the Ebola virus causes massive internal bleeding, which kills up to 90 percent of the people it infects. Now National Institutes of Health scientists are making promising advances to stop disease spread. Researchers have identified a viral protein that destroys endothelial cells, the cells that line the blood vess
