They are probrably just infected by the blightpus. The reason why they aro not present at the swamp area and Lost Izalith initial might be because the Fair Lady sucked all the blightpus near quelaag's domain, avoiding further contamination.

Upon further inspection I not only confirmed this man’s statement but I am now writing this with bleach in my eyes

why is this allowed

Finally a reason to visit blighttown

It's the blowdart snipers that are spread around the upper Blighttown area. They hit you from a distance and inflict toxic status. Try your best to keep moving and they should miss you most of the time.

The term "NG+" is short for "New Game +". You can learn all about it at the [[New+Game+Plus]] page: https://darksouls.wiki.fextralife.com/New+Game+Plus

"NG+" is short for "New Game +", and it refers to the state of playing the game over again from the beginning while retaining the level, experience, equipment, et cetera from a previous run. It is an option in many games, including Dark Souls. In Dark Souls specifically, NG+ provides enemies with greater health, that deal greater damage, and that drop more souls, as compared to their counterparts on NG, which stands for "New Game", referring to a totally fresh game started from scratch. After completing the game on NG+, the game can be restarted yet again with the same character, and we call that NG+2. Enemies health, damage, and souls are, once again, enhanced over NG+. The ultimate challenge is NG+7. Beyond that point, the game may be restarted while retaining everything with the same character, but the enemies will not change from their status in NG+7.
