Find Your Frequency is a social marketing campaign funded by the Public Health departments in King, Pierce, and Snohomish Counties. These counties banded together because their jurisdictions contain approximately 80 percent of all HIV cases in Washington state. The campaign encourages men who have sex with men, particularly those at high-risk, to test for HIV more often. It is a multichannel campaign with posters in bars, theaters, restaurants, and bathhouses, mobile and stationary billboards, testing reminder cards, newspaper ads, and online ads on hook-up websites, phone apps, and social media sites like Facebook and online news sites. All ads direct the user to test more often and to go to our website and find the HIV testing frequency that is right for them. The campaign also has information in Spanish: http://www.findyourfrequency.com/en-espanol.
