Epidemics & pandemics

"Viruses and bacteria are so small that you need a microscope to see them and yet they are powerful enough to change the course of human history. Ancient epidemics like smallpox and the plague and current scourges like HIV/AIDS and cholera have profound impacts on the way we live today. Epidemics and Pandemics takes you through the science history and current status of the severe and often scary world of widespread outbreaks."--Provided by publisher.
