I see that on the Achievements page there's an achievement for infecting other people by kissing them. Is this still possible for the 2011 outbreak? And if so, what's the minimum stage you'd have to be at to be contagious?
I'd like to know if you can get somebody elses disease when you've got one yourself also? :)
Nope, you'll only get infected by refreshing in Shadowglen, the kissing doesn't infect you. That was for 2009 outbreak only.
In 2009, you were able to spread the infection by biting. At this particular moment in the event, you cannot spread the virus by kissing, nor do I expect will it happen at all.
