Zika Virus: IOC Says Rio Will Be 'Safe Environment' For 2016 Olympics

Zika viral outbreak started in Brazil last years.

The International Olympic Committee sent the note last Friday to all national Olympic committees and outlined medical advice.

"We remain confident that there will be a safe environment for successful and enjoyable Olympic Games in Rio de Janeiro," they said in the statement.

The committee's recommendations include the advisement that pregnant women or women who are planning to become pregnant should discuss travel plans with their health care provider and that travelers in areas with Zika virus transmission should use insect repellent and wear long sleeves to avoid mosquito bites.

"If I had an Olympic ticket now, what would I do? I’d wait to see what it looks like when it gets closer," Morse told ABC News. "I’m cautiously optimistic."
