I’m watching TNG s4e26/s5e1 “Redemption”. There’s a scene where Worf’s honor is restored, by grabbing and bloodying Gowron’s d’k tahg. This got me thinking, Klingons absolutely adore blood rituals. Presumably, 24th century medicine makes contracting an STD a trivial issue. However, 21st century equivalent medicine would be far more limited.


Klingons have very different anatomies and immune systems to humans, it’s a good chance blood borne diseases don’t even affect them all that much.
It’s possible, but we aren’t really given any evidence of this
They are extremely violent, and sustain countless injuries throughout their lives. They likely evolved to be able to resist infections and heal quickly.
It’s been a while but how was the augment virus spread amongst the klingon population
Wasn’t that an engineered thing?
Engineered, yes. But it still had to spread somehow
It became airborne.
