These stats reflect information about clinical cases. No data I’ve seen factors in subclinical infections.
If subclinical cases were factored in, I’d guess less than 10 in 1000 cases are fatal.
Why are men more susceptible? In a word, urinals! Men get the vapor and/or splash of two or three previous men every time they use the urinal. Since urine is a carrier of the disease, men get much more exposure to the disease every time they urinate.
Recommendation: Urinals should be a small receptacle that has a mild amount of vacuum. Men’s bathrooms should have a dispenser of plastic shrouds that surround the penis and the plug into the receptacle with an airtight fit. There should be a medical waste container for the used shrouds. If possible, the shroud could be medically decontaminated and destroyed as the last step of urination.
I believe you would see men’s infection rates drop significantly with such a system.
Impossible? Impractical? Consider the alternatives?
