SCIUTTO: Attend, postpone or cancel? Questions about the Olympic Games in Rio de Janeiro Brazil. Many concerned about the spread of the Zika Virus there. CNN senior international correspondent, Ivan Watson, in Rio. Ivan, we saw this open letter to the World Health Organization. More than 100 doctors and professors who recommend holding the Olympics in Rio as planned, not worth the risk. Has there been a response?</s>IVAN WATSON, CNN SENIOR INTERNATIONAL CORRESPONDENT: Absolutely. The World Health Organization has come back and it says there is no global health risk to justify postponing or moving the games. It says that it insists that Zika, the Zika Virus is found in around 60 countries, more than 30 countries in the region here. And it's standing by its health advice, which includes advice for pregnant women simply not to come here for the Olympics in roughly two months, Jim, and also for people to practice safe sex. And it found Zika can be transmitted through sexual contact. And it also issued an advisory going back to May 12th saying visitors should stay away from poorer neighborhoods of Rio because there's open water and sanitation, and poorer sanitation, and that is a breeding ground for mosquitoes and it puts people at greater risk -- Jim?</s>SCIUTTO: Real challenge there. So many challenges going on in Brazil now. Ivan Watson, live from Rio. On the day that we remember fallen U.S. troops, we want to ask two distinguished American soldiers about what the troops need right now. Their message to military leaders, right after this.
