The head of the World Health Organization (WHO) has asked a panel of experts to consider whether the Rio Summer Olympics should be held as scheduled due to concerns it could spread the Zika virus.

The WHO sent teams of senior scientists to Brazil four times "to gather first-hand data on the current situation and assess the level of risk to the large number of athletes and spectators expected to attend the Olympic Summer Games," Director-General Margaret Chan wrote in a letter dated June 1.

She was responding to a request by US Senator Jeanne Shaheen to evaluate the public health hazards of holding the Games in August.

Shaheen posted Chan's letter online Friday.

"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 said
The WHO chief said the experts were due to meet "shortly," and vowed to post their advice online "immediately."

"The Olympic Games draw athletes and spectators from every corner of the globe and it's important that we understand the global health implications," Shaheen said in a statement after receiving Chan's letter.

Experts say Zika is to blame for a surge in cases in Latin America of microcephaly -- a serious birth defect in which babies are born with unusually small heads and brains.

- Guidance only -

WHO said Saturday the emergency committee meeting had already been planned for June, since it was required to do so within about three months of its last gathering, on March 8.

The exact date of the meeting should be published by the end of next week, spokeswoman Nyka Alexander told AFP in an email.
he pointed out that the experts' job was to "provide public health advice and technical guidance to the government of Brazil and the Rio 2016 Local Organising Committee on the public health risks of hosting a mass gathering such as the Olympics, and the recommended health systems that should be in place to host a safe and healthy event."

"WHO does not decide on whether to hold, cancel or postpone the Games," she said.

The WHO had previously rejected a call from more than 200 international doctors to change the timing or location of the Rio Games, saying shifting the Games would not substantially alter the risks of Zika spreading globally.

But concerns have been mounting since host country Brazil has by far been the hardest-hit since Zika began spreading in South America last year, with nearly 1,300 babies having been born there with irreversible brain damage since then.
The virus, which is mainly spread by two species of Aedes mosquito, but also through sexual contact, has also been linked to Guillain-Barre Syndrome, a rare but potentially fatal neurological disorder.

WHO spokesman Tarik Jasarevic told AFP the upcoming emergency committee meeting would include reports from many of the 60 countries worldwide affected by the Zika virus.

Discussions of how the virus is behaving, and how to rein in its spread will also be on the agenda.

The UN agency has already recommended that pregnant women avoid travelling to Zika-hit areas, including Brazil.

Women living in such areas should meanwhile delay getting pregnant, while women who have had unprotected sex and do not wish to become pregnant should have "ready access to emergency contraceptive services and counselling," according to WHO.
