Michael Phelps’s fiancee, Nicole Johnson, is scheduled to give birth to the couple’s first child in May, three months before the 18-time gold medalist looks to add to his tally at the Rio Olympics. And with all the warnings about the Zika virus, especially with regards to women, one would think Phelps might be wary of his wife and newborn son joining him for the Games.

But Phelps thinks everything will be okay.

“We’re not worried about it,” Phelps told the Associated Press on Thursday at an Olympic tune-up event in Orlando. “I think if you go into any Olympics, there’s always something that comes up.

“If she was pregnant, she definitely wouldn’t go. But she’s fine about it. She’s not missing it. And I wouldn’t want the little guy to miss it either. He won’t be able to remember it. But he’ll have a story to tell.”

The U.S. Centers for Disease Control and Prevention has advised pregnant women or women who hope to become pregnant to avoid traveling to the Rio Games because of the Zika virus, which can cause birth defects. Since last year, Zika has infected an estimated 1.5 million Brazilians.
