A different bit of research [1] says this isn't necessarily a respiratory illness, but one that attacks the red blood cells, blocking their ability to transfer O2, and causing free iron to spike in the body. The body ultimately binds into storage in the alveoli, but at too high of a rate, causing that glassy lung imaging. Women typically have lower blood iron levels than men, so once again are starting from a "safer" level.
