Description :
The world has changed drastically since the 1918 Spanish Influenza Pandemic. Ease of travel and the vast increase in the flow of information, not to mention the far more numerous world population, mean that public health threats can spread much more rapidly and in far different form than they did many years ago.
We have to worry about more than just germs these days. Public health officials concern themselves not only with natural diseases and their epidemiology, but with any threat that could interrupt health services and delivery of clean food and water to the general population.
Technology has created wonders in healthcare world, but it has also opened vulnerabilities our ancestors would have never imagined. From cyber and terrorist attacks that could disrupt power grids to bioengineered viruses that could spread at a terrifying rate due to the closeness of urban populations, public health officials are working to combat strange new contingencies every day.
