U.S. Olympic and Paralympic athletes and staff who traveled to Rio de Janeiro, Brazil, for the 2016 Summer Games did not become infected with Zika virus but did test positive for other tropical, mosquito-borne viral infections, including West Nile Virus, Dengue Fever and Chikungunya. Results from the University of Utah Health-led study will be reported at IDWeek, a national infectious disease conference being held in San Diego.
