This is my first Pandemic event and I was wondering exactly how long does it usually take to become a full blown zombie?

Edit: I believe someone said it'd take a week to fully become a zombie, though.

Well, with these new viruses it takes 14-16 hours to obtain the next stage and there are a total of 8 stages. So between 112 hours - 128 hours or between 4-5 days, roughly.

Thank you.

I think I have had my virus that long and I havent really moved foward just stayed the same.
