Community engagement has emerged as a critical component in the effective control and elimination of neglected tropical diseases (NTDs), particularly in regions with persistent stigma and limited healthcare access. Drawing on case studies from Brazil, India, and Nigeria, this opinion piece explores how community-driven initiatives have successfully improved leprosy awareness, reduced stigma, and fostered early case detection and treatment adherence. The importance of culturally sensitive, inclusive approaches in health education and stigma reduction campaigns is highlighted, emphasizing the potential for community engagement to enhance national leprosy programs and contribute to the World Health Organization's Zero Leprosy Strategy.

Large prospective clinical trials are underway or planned that examine the clinical utility and cost effectiveness of genome-based newborn screening (gNBS). One gNBS platform, BeginNGS, currently screens 53,575 variants for 412 severe childhood genetic diseases with 1,603 efficacious therapies. Retrospective evaluation of BeginNGS in 618,290 subjects suggests adequate sensitivity and positive predictive value (PPV) to proceed to prospective studies.

Genome-sequence-based newborn screening (gNBS) has substantial potential to improve outcomes in hundreds of severe childhood genetic disorders (SCGDs). However, a major impediment to gNBS is imprecision due to variants classified as pathogenic (P) or likely pathogenic (LP) that are not SCGD causal. gNBS with 53,855 P/LP variants, 342 genes, 412 SCGDs, and 1,603 therapies was positive in 74% of UK Biobank (UKB470K) adults, suggesting 97% false positives.
