<p>We screened by molecular biology 192 stools of animals under 12 months (pigs, small ruminants and cattle) belonging to family farms located in Bangui and its surroundings. To determine if there are exchanges of EV between these animals and humans living in their contact, we also screened 197 stools of children under 5 years old, living in contact with farm animals and 356 stools of children under 5 who did not live in contact with farm animals (control group). The animal and humans samples were grouped into pools according to their place of residence and the species.</p>
