When the Rio Olympics are sex at the office videosall said and done a couple weeks from now, they may well be remembered only for the competition and joy they brought to the world.

But right now, all anyone can talk about is how the water around Rio is toxic sludge and athletes are readying for war with a mosquito-borne virus.

The Zika threat

The Zika virus is a serious threat to pregnant women, as it can cause birth defects in their children. Its presence in Brazil -- home to people from all corners of the globe over the next two weeks -- has stoked fears of a massive outbreak.

But the threat of a massive Zika outbreak is not likely to rise above concern into the realm of reality.

Though Zika has infected around 1.5 million people in Brazil, the concentration of those infected is an area hundreds of miles north of Rio, where tourists and athletes are not likely to venture.

There's not much risk of contraction, which is why the World Health Organization told the world in June there was no reason to delay the games due to the virus.

Of course, that's not to say that being prepared for the virus won't hurt. U.S. soccer goalie Hope Solo has taken that thought to heart.

The toxic water

Though tourists and athletes may not actually encounter the Zika virus in Rio, they are much more likely to come into contact with its water, given Rio has lots of famous beach to go around.

The problem is that the water is full of dangerous bacteria and adenoviruses. Scientists have advised people to not put their head underwater when they take a dip because the bacteria and viruses could easily wind up in your mouth and nose.

Sewage is constantly dumped into the water around Rio and although officials promised to clear up 80 percent of water pollution by the time the Games began, it has not happened.

Athletes have been concerned about sewage affecting their competitions as well. Sailors and surfers have had to navigate chunks of plastic and other muck in Guanabara Bay, where they've been practicing for their various competitions.

Terrible residences for athletes and media

Athlete housing woes at the Olympics range from the comical...

...to the potentially dangerous.

Just two weeks ago, the majority of buildings in Olympic Village, where athletes will stay, had not even passed safety tests. Some buildings were leaking gas and water. Others lost power.

On the less dangerous but more frustrating side, showers in many residences broke apart or didn't work at all.

Olympic construction of all kinds has been suspect in Rio since it began. Workers have had to play catch up, and some structures have simply collapsed in the run-up to the Games.

Whether the lingering issues transform into something more... we'll see in the coming weeks.

Crime and police killings

Australian team officials say the team was robbed of Zika-preventive shirts and other items during a fire drill. A Chinese hurdler was robbed immediately after an apparently drunk man vomited on him.

In addition to the common crime that has been and will be a concern for athletes, tourists and residents alike, the potential for police violence looms large as well.

Human Rights Watch and Amnesty International have both dubbed Rio's police as the most dangerous on the planet and, though police killings in Rio have gone down over the past decade overall, they've begun to increase again over the past few years and even more so in the run-up to the Olympics.

In April, police killings were up 10 percent compared with the same time period in 2015, a year that itself saw a significant increase from 2014.
