HIV and sterilisation: a legal victory in Kenya After a nine-year legal battle, four Kenyan women living with HIV have shared their stories with BBC Africa, of how they were sterilised without informed consent. They have now received compensation, and the recognition that the procedures they went through at a public hospital were carried out because of their HIV status. Health correspondent Dorcas Wangira tells us about meeting them, and the legal significance of this ruling. Lost and found: Indonesia’s rare echidna Pristine forests, crystal clear water, and an ancient species of animal that was believed to be extinct - BBC Indonesian's Famega Syavira travelled to northeastern Papua to report on the rediscovery of Attenborough’s long-beaked echidna.
