The World Health Organization said on Tuesday it will convene experts next week to discuss the Zika outbreak, including its impact on the Rio Olympics, as new research suggests only a slight risk that more tourists will be infected at the Games, according to Reuters. The emergency meeting set for June 14 will be the WHO's third regarding the Zika virus outbreak. Such panels are required to meet every three months to review new evidence and consider whether Zika and its ability to cause a rare birth defect should still be classified as an international health emergency. The meeting comes amid intensifying concerns over holding the Olympics in Brazil, the country hardest hit by Zika. Brazilian authorities have confirmed more than 1,400 cases of microcephaly in babies whose mothers were exposed to Zika during pregnancy.
