Lately, there is an emerging interest in the concept of ‘population-at-risk’ (PAR) in the context of leprosy. Knowing the PAR enables us to target tailor-made interventions to achieve our common goal of Zero Leprosy.
For vector-borne infectious diseases, it is simple to estimate the PAR as it is mainly based on vector incidence. For leprosy, it will be more challenging, because there is no clear definition of the population at risk. Factors like natural immunity, non-infectious leprosy cases and hidden cases should be taken into account in the estimation.
NLR has incorporated a PhD project on Transmission in the PEP++ Project. Part of this project focuses on the population at risk. Although figures have been roughly estimated and suggested in meetings already, it would be counterproductive if several estimates would start circulating in the leprosy world. Given the surge in interest, we would like to try and come up with a preliminary definition of the concept of PAR for leprosy and preliminary figures, and develop a plan for further study on this topic.
Therefore, NLR is organizing a one-day expert meeting on Wednesday 14 March in Amsterdam. Among the participants will be experts on TB, leprosy, other NTDs, public health, epidemiology and modelling.
ILEP members’ staff who are interested in this topic and want to attend this meeting and/or contribute by sharing their expertise, please contact Anneke Taal at email@example.com.
