Why does the blight affect undead?

I am curious about this.

In the siege of lordaeron, it looked the only thing you needed to protect yourself from the blight is a gas mask which suggests that it is airborne and only harms you when you breath it in. The rest of the flesh is exposed to it and does not seem to be absorbed through the skin or damage the skin in any way.

However, the undead do not breath. So even without a gas mask, no air would be getting sucked into their lungs. Even if some air did get to their lungs, the lungs are not functional anyways so nothing would get damaged.

Also it should be noted, that if this blight is a disease or some sort of "corruption", it should still not affect undead because undead would be immune to disease since they are not alive and would also be immune to corruption since it was that same corrupted force that created them (necromancy).

I think this is another example of Blizzard nerfing the undead's true (human) potential.

TLDR: Let undead inhabit Lordaeron despite the blight.
But you’re not immune to these hands.
*karate chop*
While undead do not breathe, i'd imagine they'd still need to cycle air through their vocal chords to speak, so maybe the gas masks are for that?

The blight is less of a disease and more of a nasty chemical weapon from what I know, it even affected the lich king at the wrathgate, though it was applied differently (not gaseous form)
The Blight was designed specifically to target the living and the dead, since Sylvanas originally intended to use it on the Alliance, the Horde and the Scourge.
The blight is magical in nature and was made specifically to kill both living and undead.
The blight is a chemical weapon that was designed to rot the body from the inside out and reduce it's victims to a puddle of green sludge.

It has always effected the undead just as well as it effects the living. Arthas had to run back inside icecrown, with green slime streaming out of his armor.

It's never quite explained why gas masks defend against it. Perhaps the chemical reaction that reduces people to slime starts when it enters the lungs, and it just seeps into the undead even if they aren't actively breathing.
it's been a while since the wrathgate, it could be possible that they created a variation of this blight that for what ever reason needs to be inhaled to take affect. This makes it easier to blight the enemy on the open field while reducing friendly casualties, so it's probable.

Blizzard tends to overlook details sometimes though, so the gas masks may have just been for aesthetic when worn on the undead apothecaries.
The original blight was modified by Apothecary under the order of Sylvanas to combat both the living and the Scourge.
It was made to kill the scourge...who are Undead.
I always thought the blight was more of a chemical weapon than disease.

The one human at the wrathgate was melting at the face

Stands to reason if it dissolves human flesh, it would dissolves dead flesh as well

I always imagined it ruptures blood cells/vessels and causes the tissue to decay and break down.

Sort of like snake vemon. You can touch it on your skin and be fine, but if it got into your lungs/blood, the tissue starts to decay and necros very quickly

This would explain why it can harm undead even though they don't breathe. You guys have exposed veins/tissues that should be covered by skin. So if it touches those exposed areas, you start to dissolve
Because it was engineered by the Apothecaries and Varimathras to affect undead so they would fight the Scourge and Sylvanas.
Putress designed the blight to kill the scourge AND the living.
I remember when your undead got bonuses for fighting on blighted ground.

I use to keep setting farms feel until the whole map was covered, then go in for the kill.

And yet it can be cured with simple bandages. This is the real reason why they did away with first aid for everyone that wasn't a tailor! The truth is out there people, wake up!

Arthas was still a living, breathing human, even if he was corrupt by Ner'Zhul.

Ehhhh that's somewhat up for interpretation. Arthas was a death knight. Those are usually not alive as we know it. Plus it's canon that the first soul eaten by Frostmourne was Arthas'. So....
"DEATH TO THE SCOURGE AND DEATH TO THE LIVING!" - High Apothecary Putress

The Blight is designed to kill everything. It is a WoMD, which is why its development was secret, and its use forbidden by former Warchiefs.

Undercity was once under armed surveillance by Kor'kron guards, after the Wrathgate incident, just for this reason.

The fact that Sylvanas has never abandoned the program, regardless, says a lot about her, really.

Lore wise.. the Forsaken developed a version of the plague that affected the Undead during WoTLK.. hence why Arthas was forced to retreat at the Wrathgate during the attack that kicked off Putress and Varimathras's coup.
