Current Any% WR has no info on which type of plague they used, I personally think this means there should be separate categories for each type of plague.

That is the individual level leaderboards. The any% can be any disease as the goal is to just be as fast as possible (without cheats). Any disease goes

Nano Virus

isn't any% completely pointless since it's just the fastest IL

It's not. any% was Neurax Worm once upon a time.

i... don't see how that's relevant?
