No Apparent Zika Virus Spread at Rio Olympics, WHO Says

Zika is still a Public Health Emergency of International Concern, the WHO said.

The health organization chalked the successes up to Brazil's "successful application of appropriate public health measures," during the games. In June, it also noted that the games were being held during Brazil's winter, when the transmission of diseases like Zika are typically lower.

While the WHO was upbeat about the Olympics, it said that Zika remained a Public Health Emergency of International Concern (PHEIC), because it continues to spread to new areas around the world and because many people are still largely ignorant of the virus and its consequences, particularly for women who are pregnant or may become pregnant in the near future.

Declaring an outbreak a PHEIC requires officials to believe that the virus can pose a health risk for several countries and that it "potentially requires a coordinated international response."
