It examines demographic transitions across countries like Sri Lanka, and the effects of the U.S. baby boom. Despite a low Total Fertility Rate, baby boomers are affecting population dynamics, contributing to concerns about sustainability as projections suggest a rise to 9.

It identifies criteria for establishing causation and cites John Snow's cholera maps as an early epidemiological example. The text underscores the health impact of smoking and mentions environmental health risks reported in the media. To make informed decisions regarding health claims, the author recommends five criteria for evaluating such reports.

It discusses the history of pandemics, the mutation of influenza viruses leading to new strains, and the necessity for updated vaccines due to antigenic drift. Various vaccine types and the development process are outlined, alongside treatments including antiviral drugs and their resistance issues.
