The City of Chicago launched another engagement tool to combat the spread of COVID-19 in Chicago—a Snapchat lens. The social media platform is popular amongst Millennials and Gen Zers, a demographic that has seen a recent rise in case numbers in Chicago, and which the City believes is key to stemming the virus.  To encourage users to wear masks when in public, this first-of-its-kind Snapchat augmented reality lens deploys new technology that only allows the user to unlock the lens when they put on a mask. Known for offering its users “Easter eggs,” or hidden surprises found only through unique codes, Snapchat collaborated with Ogilvy-Chicago to design an AR lens that is “quintessential Chicago.” The City worked closely with Snap Inc. and Ogilvy to produce, refine and complete the new designs to ensure they were aligned with the City’s current public health awareness initiatives, specifically, the ‘We Are All ONE Team: Team Up, Mask Up’ campaign.  The best way to protect yourself and others from COVID-19 is to practice good hand hygiene, stay six feet from others, and wear a face covering when going out in public and when around people who don’t live in your household or at risk.
