Brazil Dengue Outbreak Exposes Tough Challenge for Rousseff

An epidemic of dengue fever is fanning public anger over what Brazilians say is President Dilma Rousseff's biggest challenge - the sad state of the national healthcare system. About 750,000 cases of the mosquito-borne virus have been confirmed this year in this country of 200 million people, leading to waits of four hours or longer at some hospitals. The disease, which causes fever and joint pain, has killed 229 people so far this year - up 45 percent from the same period in 2014.
