The statement came as worry mounted that the mosquito-borne virus, which has spread across much of Latin America and which can lead to severe birth defects in babies, might spread further when the Olympics begin in August.
"The Committee concluded that there is a very low risk of further international spread of Zika virus as a result of the Olympic and Paralympic Games as Brazil will be hosting the Games during the Brazilian winter," the WHO said.
The global health agency explained that the intensity of the transmission of viruses like dengue and Zika "will be minimal".
