An International Congress on Leishmania & Leishmaniasis

Why ? Cutaneous, mucocutaneous and visceral leishmaniases are serious diseases, which are vector-borne and wide-spread in more than 90 countries, putting 350 million population at risk. WHO estimates an annual incidence of 2 million and a total of 12 million current cases. The causative agents are various species of trypanosomatid protozoa in the genus of Leishmania, which are excellent models for aspects of laboratory studied in cell/molecular biology, biochemistry, immunology of host-parasite interactions.

Who ? Anyone interested in Leishmania and leishmaniasis is welcome to participate, including individuals of private and public academic institutions, charitable organizations, advocacy groups, government officials/ representatives, for-profit private sectors and their friends/affiliates.


When/where ? Every four years preferably in a country endemic to leishmaniasis.

What ? Bring laboratory researchers and field workers from all disciplinary areas together for sharing new discoveries and exchange of new ideas. Provide opportunities of international collaboration, industrial participation, charitable donation and training of the next generation.

How to host WL



Leishmaniacs will be informed (e-mail past WL participants) of the guidelines for preparing the application and the submission deadline in WorldLeish website as a link to “How to apply for organizing WL”, in which applicants are asked to address issues described in the document



  • All applications will be acknowledged and announced
  • Review: Applications will be reviewed by the International Scientific Committee members



  • Applications will be ranked according to reviewers’ scores and comments
  • The outcome plus scores and comments will be posted anonymously in the WL website
  • Applicants and all leishmaniacs/ previous WL participants will be notified
  • Comments from all leishmaniacs will be welcomed for a period of one month
  • Leishmaniac comments will be posted in the WL website
Bob’s passing has saddened us until now. We will never forget his invaluable contributions to the scientific programs on sand fly vectors and canine leishmaniasis in all the previous WL meetings. He had been indeed our go-to expert as a member in the WL Scientific Committee for these and other areas about leishmaniasis. His passing is a great loss to all of us and to all the leishmaniacs.
