Sri Lanka's Mawbima holds the distinction of printing "the world's first mosquito-repelling newspaper," according to Core77. With the help of advertising agency Leo Burnett, the publication carried out a multi-step campaign in an attempt to help combat dengue, a mosquito-borne disease. Mawbima began by placing large posters at bus shelters throughout the country. Each of these notices was coated with citronella, a natural insect repellent. Following that, Mawbima published a week-long series of educational articles detailing ways to combat the disease, before finally printing a special edition of the newspaper on World Health Day. The ink used was mixed with citronella in hopes of dissuading the deadly mosquitos from feeding on readers.
