Get stabbed by someone who has that title set as his active callsign.
it means, if someone who has the infected title and is using it knifes you, then you are "infected" by them, so you get the title. STD works the same way, but you have to knife someone else who has the title and is using it, then you get it.
Infected is a title that you can only get by gettng knifed by someone who is wearing this title. I have it and it is not so hard to get. I just went into a free for all and this noob was only knifing and he had the Infected title on so i got knifed by hm and got the title infected. If you want it easier you can always boost for it. have your friend put the title on in a free for all and have him knife you. So HAPPY GETTING INFECTED hope it helped!!!!!!!!!!!!!. -thewoodking34 my name if you got PS3.
