There are a couple of campaigns that are trying to reduce the stigma associated with HIV. Both have the same message, but use different slogans.

THT has a campaign called “Can’t Pass it on”:

They say: Medical evidence has shown that people on effective HIV treatment can’t pass it on. If everyone knew this, we could bring an end to stigma around HIV. Not only that, but we could stop HIV transmissions all together. We’ve launched our Can’t Pass It On campaign, to spread this message far and wide.”

And Prevention Access links to a number of campaigns which say “U=U’:

Undetectable = Untransmittable

Surveys show that even in the MSM HIV community, less than half the people surveyed understood this…and less than 10% of the general public are aware of this. So these campaigns aim to increase awareness of this really key information.
