Abstract
The incidence and mortality of kala-azar (KA, visceral leishmaniasis) in India have fallen drastically in the past few years, and in 2023 the reported KA incidence reached the threshold for elimination as a public health problem (<1 case/10 000 of population at subdistrict level). One of the strategies adopted by India's kala-azar elimination program (KAEP) was the regular independent assessment of the program implementation by teams of experts. We present the findings of assessments undertaken in 2019, 2021 and 2023, when the KAEP was in the last mile of elimination. Factors that contributed to its success were political commitment, intensified implementation, a strong network of KA partners and committed donors. Bottlenecks were observed in disease surveillance, data utilization, vector-control operations and program management at implementation. To sustain the gains and achieve validation of elimination, the KAEP should continue the following minimal essential services: optimized active and passive case detection and management of KA, post-KA dermal leishmaniasis, KA-HIV coinfection and relapse supported by vector-control interventions. Long-term measures that will sustain elimination are overall socioeconomic development, including improved living conditions, parallel with efficient surveillance and operational research that is aligned with the changing epidemiology of the disease.
