Leprosy Mailing List – June 19, 2026

Ref.: (LML) Discussion Paper: Revisiting Bacillary Persistence, Viability, and Transmission in Leprosy

From: Isabela Goulart, Uberländia, Brazil

____________________________________________________________________________

Dear Editor,

Please find attached a discussion paper entitled:

"Revisiting Bacillary Persistence, Viability, and Transmission: Reflections on the Study by Neumann et al. (2022)."

This discussion paper was prepared in response to the findings reported by Neumann et al. regarding the heterogeneous persistence of molecular markers of Mycobacterium leprae viability during multidrug therapy in multibacillary patients.

The discussion explores some conceptual and biological implications of these findings and raises questions regarding the relationships among bacillary viability, infectivity, and epidemiologically relevant transmission in leprosy.

We hope it may stimulate discussion among members of the Leprosy Mailing List and would greatly appreciate comments and perspectives from colleagues.

Kind regards,

Dr. Isabela Maria Bernardes Goulart

Thank you very much for your continued support of the global leprosy community and for everything you do to keep us connected.

With my warmest regards,

Laila

Dear Pieter,

I hope you are doing well.

I am writing to kindly ask whether it would be possible to announce, through the Leprosy Mailing List, an online event that will take place on 30 June 2026 and is being organized within the framework of the 30th Anniversary of the Community of Portuguese Language Countries (CPLP).

The Community of Portuguese Language Countries (CPLP), an intergovernmental organization comprising the nine Portuguese-speaking countries, is celebrating its 30th anniversary in 2026.

The event, entitled “Leprosy: Epidemiological Situation, Challenges and Cooperation Strategies in Portuguese-Speaking Countries”, will bring together experts and representatives from several Lusophone countries to discuss the current epidemiological situation, ongoing challenges, and opportunities for technical cooperation in the field of leprosy.

The meeting will be held online and conducted in Portuguese. Although the language may limit participation from some members of the mailing list, I believe the topic may nevertheless be of interest to colleagues involved in international leprosy programmes and cooperation initiatives.

If you consider it appropriate, I would be most grateful if you could share the attached announcement with the mailing list.

Thank you very much for your continued support of the global leprosy community and for considering this request.

With my warm regards,

Dr. Laila de Laguiche
Founder and President
Alliance Against Leprosy (AAL)
Brazil / Switzerland

Leprosy Mailing List – June 9, 2026

Ref.: (LML) Infolep monthly overview of new publications on leprosy, May, 2026

From: Elizabeth Talatu Williams, Amsterdam, the Netherlands

____________________________________________________________________________

Dear colleagues,

We are pleased to share the May 2026 edition of the Infolep Newsletter, featuring recent publications, case reports, and global updates from the leprosy field.

This month’s featured articles focus on key developments in health systems strengthening, conflict and health, and psychosocial wellbeing. Topics covered include findings from a global survey on strengthening frontline capacity for skin-related neglected tropical diseases, the impact of armed conflict on leprosy in Tigray, Ethiopia, and new research examining psychosocial resilience, social support, stigma, quality of life, and mental health among persons affected by leprosy.

The case reports in this issue reflect the ongoing diagnostic and clinical challenges in leprosy, including atypical clinical presentations, preserved sensation in lepromatous leprosy, neurological manifestations in non-endemic settings, and rare disease presentations that may complicate diagnosis. These reports reflect the importance of clinical awareness, timely diagnosis, and appropriate management.

This edition also includes updates on funding opportunities, including the DermImpact Grant Programme and the EDCTP Prizes 2027, alongside news on national programme developments, stigma reduction initiatives, policy discussions, and advocacy efforts from around the world.

We hope this edition provides useful insights and supports your continued work in advancing leprosy research, care, and inclusion.

Please feel free to contact us if you would like access to full-text versions that are not available on Infolep, or if you would like our support with literature searches.

Warm regards,
Elizabeth Talatu Williams
