If worried about this type stuff, cover any open wounds with neosporin and band aid or better yet liquid band aid stuff, two coats & once dry do the neo and band aid, or Vaseline and watch for early sighs of infection.
Don't know if more this year, or more attention paid to it on the wwww.
Most cases come from those with compromised immune systems, diabetic, things of that nature. Yes it's a possibility but millions of folks play in the SW water every day and nothing happens to them, so it's a small one.
Just watch for signs w/any open wounds, and if someone is medically in a way like above consider not going in the water. Best you can do when down there.
Have a great time.
