"After much deliberation with my family and coaches, I am making this decision for a variety of health concerns including the uncertainty around the Zika virus," Raonic, 25, said in a statement issued by Tennis Canada.
"This was a difficult, personal choice and I do not wish for it to impact the decision of any other athlete heading to the Games. "
The Zika virus, which the World Health Organization says is spreading rapidly in the Americas, has been linked to severe birth defects in infants born to infected women, and possible neurological problems in adults.
