UN to ask expert committee to assess Zika risk at Olympic Games

- The World Health Organization's chief says she will convene an expert committee to consider whether the Rio de Janeiro Summer Olympics should proceed as planned, following concerns raised about the threat of the Zika virus, the Associated Press reports.

In a request last month, U.S. Senator Jeanne Shaheen asked WHO Director-General Dr. Margaret Chan to evaluate whether the Rio games this year should be delayed or postponed. Chan said in a letter released by Shaheen on Friday that WHO has sent senior scientists to Brazil four times to assess the risk of Zika to the approximately 500,000 athletes and visitors expected to attend the Aug. 5-21 games in Brazil.

Brazil has been the hardest-hit of the approximately 60 nations that have reported Zika outbreaks — and has by far the most cases of brain-damaged babies linked to the virus, almost 1,500.

"Given the current level of international concern, I have decided to ask members of the Zika Emergency Committee to examine the risks of holding the Olympic Summer Games as currently scheduled," Chan wrote.

WHO said the meeting date would likely be fixed next week, AP says.

Chan said she "deeply appreciated" the concerns raised by Shaheen in her letter to WHO last month, which cited a commentary by Canadian professor Amir Attaran. He argued that holding the Olympics as planned would result in the avoidable birth of more brain-damaged babies.

Last month, Attaran and more than 200 other experts signed an open letter asking WHO to convene an independent group to consider if the games should be delayed or moved "in the name of public health." WHO rejected such calls and said "cancelling or changing the location of the 2016 Olympics (would) not significantly alter the international spread of Zika."
