Olympic leaders are wrestling with several big issues, most of which are not widely-known outside of Brazil:
Although these issues won't shut down the Olympic Games, they may have a major impact on the events, the athletes and the fans.
The Brazilian Health Ministry reported that more than 90,000 suspected Zika cases were registered in Brazil during February through April 2016. However, the Centers for Disease Control and Prevention (CDC) has not issued a warning telling U.S. citizens not to attend. Instead, they published a list of guidelines to follow to minimize Zika risk at the Rio Olympics.
Each country is establishing guidelines to protect their athletes. For example, South Korea will provide their athletes with Zika-proof uniforms, including chemically-enhanced fabrics to repel the mosquito and uniform designs that include long sleeves and long pants.
The reported levels of viruses and bacteria equal the same level of contamination as raw sewage. They are not life-threatening; but, they can cause a serious health risk for athletes and visitors, particularly for watersports.
Prior to receiving the bid for the Olympics, Brazil had promised to clean-up the city's sewage problems and build treatment centers before the Olympics; but, the Brazilian government has since reported that the planned level of clean-up will not be possible.
A spokesman for the Rio games has reported that, in order to stay on budget, the 10,000 athletes participating in the Olympics will not have air conditioning in their bedrooms unless they pay for it themselves. Air temperature during the Olympics is projected to exceed ninety degrees.

The individual athletes were selected by the Executive Board of the International Olympic Committee:
