Maasai Mbili is a group of artist-activists who live and work in Kibera, Africa's largest urban slum on the outskirts of Nairobi, Kenya. Aside from overcrowding and unsanitary living conditions, the lack of a clean and safe water supply makes the slum an ideal breeding ground for the coronavirus. Self-explanatory wall paintings all over the narrow streets of Kibera remind the residents that Covid-19 has long since reached them and is now another challenge for the residents of Kibera, especially the children.
