Undoubtedly tragic.The first case was the opinion of the physician that examined the kid who is now paralyzed. The second case I don't have detailed information about but he had COVID and lung rupture. The other cases that were known in the country were known to have had COVID. It is very unusual to have these types of injuries/deaths and the common theme is COVID with them.
Without all the info it's not possible to discuss this.
Most folks who DWD don't get into accidents killing others on their first time DUI but the ones that do, and many do, commit horrible tragedies. It catches up with them as they continue to DUI.
Fact is that a lot is unknown about COVID and its long term affects on human physiology and diving is even less.
Aside from your metaphor -- not appropriate -- far more people go diving who've had Covid and "survive" than tragically succumb to some DCS.
I've had covid and have done a lot of diving post covid without consequences. Maybe I'm just lucky? I don't think so; I follow the decompression algorithms and, amazingly, I don't get DCS.
Can’t speak for others
