Ebola-chan is an Internet meme depicting a moe anthropomorphization of the Ebola virus and was popularized on 4chan. The first known image of Ebola-chan began on the Japanese social media site, Pixiv, in 2014. A few days after, it was posted 4chan's /pol/ (politically incorrect) thread, who began posting messages praising Ebola-chan. Soon after, 4chan users began spreading the meme to Nairaland, the largest online message board in Nigeria, accompanying images of Ebola-chan with racist messages and associated conspiracy theories. This included claims that Ebola was CIA-made and that white people were performing rituals for Ebola to spread. The meme's spread has been considered racist and has been attributed to increased mistrust between West Africans and medical professionals.
