I wish they'd focus more on things like MRSA and KPC which kills far more people in this country and are far more deadly. These diseases are easily spread and there is no cure for them. While not trying to diminish the cause to fight Ebola, frankly there are a lot of things far deadlier in this country that people should be worried about.
The cases in Texas I think can be squarely blamed on incompetence from the Dallas hospital.
In the case of KPC, Congress has basically put their head in the sand and handtied the CDC and FDA from effectively studying and fighting it, thanks to the livestock lobbies Frontline has a good episode on this. It doesn't help that congress has cut the budget of the CDC significantly over the last decade and played politics to make it difficult to study and fight the causes.
As it is, the CDC had to cut back on their research on Ebola due to the budget cuts and the delays in the worldwide community for fighting and funding the fighting of Ebola aren't helping matters either. If the Dallas hospital wasn't so incompetent, there's a good chance Thomas might have survived and nobody else would have become infected.
