Most neglected tropical diseases (NTDs) are intrinsically embedded within the One Health approach: NTD researchers have already been dealing with multidisciplinary and intersectoral work for decades simply because it is essential for understanding and controlling the usually complex transmission of the pathogens causing NTDs. This long experience has already enrooted the idea of the horizontal integration of research, control, elimination and eradication strategies. The ongoing epidemiological transitions of most NTDs urges pursuing and amplifying the development of co-constructed multidisciplinary and intersectoral research initiatives for improving control/elimination/eradication processes. Lessons from NTDs may also be useful for other diseases targeted by ongoing One Health initiatives.
