The next ILS Scientific Meeting will bring together researchers, clinicians, and public health experts from around the world. Join us in Malaysia on 27-29 October 2026 to share the latest advances in leptospirosis research, diagnosis, and control.
Membership
Membership in the ILS is free and open to everyone with an interest in leptospirosis. Our primary communication channel is the ILS Google Group, where members share news, research, and announcements.
MAT Proficiency Testing
The International Leptospirosis MAT Proficiency Testing Scheme helps laboratories worldwide assess and improve the quality of their microscopic agglutination test (MAT) performance. Participation is open to any laboratory performing the MAT, and results are provided confidentially to help guide quality improvement.
