Rehema Lushombo stands in front of a chimpanzee at Lwiro Primate Centre. Lushombo, a caretaker who works with chimpanzees too old for regular direct human contact, says: ‘Our job is to create good relations with them, they’ve been in hazardous situations, poachers have killed their families in front of their eyes and caught them, they fear people. When I notice any sickness or problem I inform the veterinarian ... we enter the cage in a group to treat them.’
