Rory McIlroy Withdraws from 2016 Rio Olympics over Zika Virus Fears

Four-time major winner Rory McIlroy has confirmed he will not compete for Ireland at the summer's 2016 Rio Olympics because of the threat of the Zika virus.

Sky News reported the news:

The Olympic Council of Ireland said it was "extremely disappointed" at McIlroy's decision to withdraw but understands the golfer's reasoning, per The Independent's Cormac Byrne.

Golf is returning to the Olympics for the first time since 1904, and McIlroy was expected to represent the Irish team.

McIlroy initially sought advice over his concerns surrounding the Zika virus but announced last month he was "comfortable" with travelling to Rio, per Byrne.

However, the 27-year-old released a statement on Wednesday explaining that he is now unwilling to take the risk, per Sky News' Paul Kelso:

The mosquito-borne Zika virus has been linked to brain defects in newborn babies. The World Health Organisation (WHO) declared it "a public health emergency of international concern" in February after a number of babies were born with brain damage, per Sarah Boseley and Jonathan Watts in the Guardian.

Per Steph Cockroft of MailOnline, pregnant women have already been advised not to travel to Rio de Janeiro, but the WHO "has predicted the Zika risk in August would drop since it will be the South American winter and there should be fewer mosquitoes."

McIlroy joins Fiji's Vijay Singh and Australia's Marc Leishman in withdrawing from the Games due to concerns over the virus.

BBC Sport's Richard Conway speculated that more athletes could follow their lead:

McIlroy will be sorely missed from the 2016 Olympics given his immense profile and global following.

But as the Olympic Council of Ireland noted, per Byrne, "Now there is an opportunity for another Irish golfer to take up the chance to become an Olympian and participate in golf's historic return to the Olympic Games after a 112-year absence."
