This is no different from first responders and people trained in CPR carrying pocket mouthguards to protect themselves from other contagions.
The number of deaths for people under 30 is infinitesimally small.
Interesting. I was a guard and a guard trainer for ten years. Over the years, we realized that ventilations weren’t as important as compressions. We had our masks, and were expected to perform ‘traditional’ cpr, but unless the vic was pulled directly from the water, compressions came first — and really, if they did come from the water, the first to vents were to prime the pump to get the water out of the lungs.
You couldn’t pay me to be a guard these days, though. Not worth the legal hassles. People are so litigation crazy, they can save themselves as far as I’m concerned.
But all lifeguard training and recertifications are on hold.
