The quadrennial sporting extravaganza that is the Olympics is normally a much-anticipated event with the whole world watching. But surprisingly, the lead up to Rio 2016 has been underwhelming, to say the least, with the games being plagued by a horde of controversies which have taken the sheen off the event.
With the opening ceremony for Rio 2016 less than a day away, we take a look at five of the major issues that have plagued the Olympics this time around:-
1) The Zika threat
The outbreak of the Zika virus was the first and foremost issue that has affected the Olympics. The outbreak in Brazil, which was declared as a global public health emergency by the World Health Organisation (WHO), scared many athletes and spectators away who opted not to take a risk by travelling to Rio.
Zika is spread through mosquito bites and by having unprotected sex with an affected person and will lead to complications in pregnant woman including birth defects. In fact, several top athletes including star golfer Rory McIlroy cited Zika fears while announcing their decision to skip the Olympics.
