Dr. Elizabeth Osim Elhassan is a public health consultant with a four-decade career at the forefront of eliminating Neglected Tropical Diseases (NTDs) across Sub-Saharan Africa. Her pioneering work in research, strategy, and community-led interventions has been pivotal in shaping global health policy and practice. Dr. Elhassan co-developed foundational frameworks that have become cornerstones of NTD control and elimination, including the Community-Directed Treatment with Ivermectin (CDTI) and the integrated Community-Directed Interventions (CDI) approach. Her involvement in innovative research demonstrated how the CDTI platform could be successfully leveraged to deliver other essential health services, such as vitamin A supplementation, insecticide-treated bed nets, home management of malaria, and TB treatments, significantly amplifying its impact in public health. Dr. Elhassan currently co-chairs the WHO/AFRO Regional Programme Advisory Group for PC-NTDs (RPAG) and has served on the WHO Technical Consultative Committee for the African Programme for Onchocerciasis Control (APOC), the Mectizan Donation Program (MDP) Expert Committee, and the ESPEN Steering Committee. She has also been an executive committee member of the NNN and has chaired both the national and global NGDO groups for onchocerciasis elimination. During her 22-year tenure at Sightsavers, which culminated in her role as Technical Director of Onchocerciasis and Lymphatic Filariasis, Dr. Elhassan was instrumental in establishing National Onchocerciasis Elimination Committees (NOECs) in twelve African countries, building sustainable national capacity for disease elimination. Dr. Elhassan holds a Ph.D. in Veterinary Pathology and an M.Sc. and B.Sc. (Hons) in Physiology from the University of Ibadan, Nigeria.
