I beleive the infection rate for a bite is 95%, if I'm wrong, someone can provide a different number.
There is no mean to reduce this chance or prevent infection (except maybe the trait Thick Skin). Once it's been determined by the game, it is only a matter of time.
As such, surviving an infection form a bite (19 times out of 20) is impossible. That is why I always play with sandbox settings that make infection and death instantaneous... I always know which bite/scratch is fatal right away.
Sup boys, finally after 150h+ without any problem i have to report bug :(
I don't have gun shoot sound, without problem with reload noise. I tried change audio settings but all sounds are set loud. I can too test missing sound in advanced options. I find more player with this same issues.
Have a nice evening
