BRASILIA , Brazil, May 20 (UPI) -- Public health officials are concerned an upcoming tourist influx to Brazil will spread its epidemic of dengue fever.
Brazil, with 1.4 million reported cases of dengue fever in 2013 and the world's largest outbreak of the disease, is about to welcome millions of visitors from all over the world to its World Cup soccer tournament. Authorities are concerned tourists could carry the mosquito-borne virus back and spread it in their home countries.
