Changes in Mortality: 1900 vs 2010

Changes in Mortality: 1900 vs 2010 | Hum Geo | Scoop.it
How we die (in one chart)...

 

This infographic shows the main causes of death in 1900 in the United States and compares that with the 2010 figures.  The United States, during that time underwent what many call the epidemiological transition (in essence, in developed societies we now die for different reason and generally live longer) What are the geographic factors that influence these shifts in the mortality rates?  What is better about society?  Has anything worsened?  How come?

In the 1900s, there were more "natural" caused illnesses but not enough medicine or technology to alleviate these diseases, hence, the greater mortality rate. Presently, medicine and technology has changed for the greater good. Many of the diseases are cured and more people living longer due to this. However, mortality caused by heart disease and cancer have increased in 2010; this is probably due to higher calorie diets and exposure to preservatives and radiation.

Looking back and comparing the 1900’s to 2010, I think it is becoming quite evident that our surrounding environment and what we consume impacts our health. Honestly what kind of cancer are you not at risk of getting today? Factors can vary from the genetically altered food we consume, radiation emitted from our cell phones or even prolonged exposure to the sun. While combating harmful pathogens and bacteria may have been a critical health concern and challenge of the early 20th century, finding remedies to an increasingly toxic environment may characterize the medical needs of the 21st century.
Justin McCullough's curator insight, December 12, 2013 9:50 AM

The thing that is positive about this infograph on how we die, is that our mortality rate has indeed gone down a whole lot since 1900. As the article states, we have become more aware of the bacteria taht surrounds us and have learned to be more clean because of it. This has surely cut down the rate in which people die by infectious diseases. However, it is interesting to see that heart diseases remains in one of the top ways that we die, even to this day. Accident deaths have also significantly dropped, probably due to the safety measures taken in the workplaces, or the technological advances that have made fighting wars, less deadly than during the 1900s.

Role of U.S. Airports in Epidemics

Public health crises of the past decade — such as the 2003 SARS outbreak, which spread to 37 countries and caused about 1,000 deaths, and the 2009 H1N1 flu p...

 

The spread of infectious diseases is inherently connected to the mobility of infected.  Airports are important nodes in this complex transportation network.  Which airports would have the greatest potential to spread diseases?  At MIT, they've gathered data that incorporates variations in travel patterns among individuals, the geographic locations of airports, the disparity in interactions among airports, and waiting times at individual airports to create a tool that could be used to predict where and how fast a disease might spread.  To read more, see the associated article.
