There is no chance that the Rio Olympics will be cancelled because of a Zika virus outbreak, Brazil has said.
The authorities said there was no risk to athletes and spectators - except pregnant women - at the August event.
Earlier, the World Health Organization (WHO) warned a disease linked to Zika posed a global public health emergency requiring a united response.
The infection has been linked to cases of microcephaly, in which babies are born with underdeveloped brains.
Experts are worried that the mosquito-borne virus in Latin America is spreading far and fast, with devastating consequences.
