Leptospirosis Burden Epidemiology Reference Group (LERG)


WHO's Initiative

Our Goals:

  • To provide estimates on the global burden of Leptospirosis according to age, sex and region.
  • To increase awareness of and commitment to the disease in developing countries.
  • To encourage developing countries to undertake active disease surveillance and strengthen control measures.



These efforts will ultimately enable policy makers and other stakeholders to translate knowledge into policy by setting appropriate evidence based priorities in the area of Leptospirosis disease control and prevention.

Our Actions:

To coordinate and direct global research and action against human Leptospirosis, the WHO has established the Leptospirosis Burden Epidemiology Reference Group (LERG). It has been assigned the following tasks:

  • Reviewing and appraising epidemiological evidence based on commissioned reviews and studies.
  • Developing epidemiological tools to estimate disease burden.
  • Estimating and expressing disease burden through summary measures of population health (including disability-adjusted life years).
  • Identifying technical gaps for research.


The WHO Secretariat for LERG is based at the Department of Food Safety and Zoonoses (FOS) with functions of facilitating, coordinating, guiding and monitoring the work of the LERG.
