A new Gallup poll reveals that healthcare costs, access to care and Ebola are the top three concerns of Americans. Gallup has measured public perceptions of the leading U.S. health problem annually since 1999. This year's results are based on Gallup's annual Health and Healthcare survey, conducted in early November. At the time of the new survey, only one of the four people who had been diagnosed with Ebola in the U.S. was still being treated, and the other two surviving patients had already been declared virus-free. Gallup researchers said that it is a testament to the gravity of the Ebola virus that it still sparks relatively high public concern several weeks after the peak of the U.S. scare. Article
