How are inequality and discrimination shaping data about COVID-19, and who is being left invisible and uncounted? On the launch of her new book on data and human rights, Sara (Meg) Davis speaks to social worker and rights activist Jolovan Wham in Singapore, who describes how thousands of migrant workers are being detained in overcrowded dorms, and were missed by the official mobile contact tracing app. In Geneva, Dr. Shirin Heidari (GENDRO) and Marina Smelyanskaya (Stop TB Partnership) address the global need for feminist principles and respect for human rights to gather data on COVID-19. Davis’ new book, The Uncounted: Politics of Data in Global Health is available from Cambridge University Press.
