I tend to react to the Ebola scare with the following:
A recent article from The Washington Post provides further reasons to react in such a way:
The long history of associating immigrants and disease in America and the problematic impact that has on attitudes toward immigrants should make us sensitive to the impact of “othering” African immigrants to the United States in the midst of the current Ebola outbreak in West Africa. Scare-mongering about infinitesimally small risks in one context serves no purpose to the greater good of trying to curb disease transmission and relieve people’s suffering in another context.
The article is full of links to various studies on colonial history, political history of immigration, Ebola breakouts, etc.
An excellent read. Check it out.
