Persisting Pandemics

Syphilis, AIDS, and COVID disprove any belief that scientific discoveries have ended the period of acute epidemic diseases that once defined 19th century life and replaced them with chronic cardiovascular diseases and cancers. Today, we cope with a greater array of epidemics than those who lived during the 19th century, even though we have the biomedical means to control them. Our cumulative experience with epidemic diseases, together with our attempts to eliminate them, remains a continued component of our existence.
