"public health officials exploited the case to scare gay men into practicing safe sex." So, if they could mount a large 'fear' campaign to keep the majority of gay and heteros much more mindful in taking precautions for a year and a half, they can greatly limit the spread. I just don't seem them being able to eliminate it this way since it wouldn't be feasible to expect anything near 100% compliance. Eventually complacency would reemerge as would it's spreading. So really, the campaingn would probably just buy some more time before it spread again.
