ABSTRACT

The grandiose optimism rested on two false assumptions: that microbes were biologically stationary targets and that diseases could be geographically sequestered. Each contributed to the smug sense of immunity from infectious diseases that characterized health professionals in North America and Europe. The goal was nothing less than pushing humanity through what was termed the "health transition", leaving the age of infectious disease permanently behind. Urbanization and global migration propel radical changes in human behavior as well as in the ecological relationship between microbes and humans. Using powerful medical weaponry developed during the postwar period—antibiotics, antimalarials, and vaccines—political and scientific leaders in the United States and around the world pursued a military-style campaign to obliterate viral, bacterial, and parasitic enemies. Bolstering research capacity, enhancing disease surveillance capabilities, revitalizing sagging basic public health systems, rationing powerful drugs to avoid the emergence of drug-resistant organisms, and improving infection control practices at hospitals are only stopgap measures.
