I went to a toxicZone, to get hit ~4 times by an infected.
That caused 2 cuts and as soon as I stopped to bandage I received 3rd one from apparently broken jacket.
This obviously led me to death through bleeding out. I came fully prepared, with 2 ductapes to not have time to use them once; because how on earth do you fix ruined jacket :)

Before infected buff they were to weak too, but acceptable.
It feels like the developers did not condsider this feature along with increasing infected damage towards clothing.
Now NBC stats are both lowered in comparison to normal ones, and infected buffed so it makes them way too weak.
