Assessment of LF status in Two Urban Settings of Benin (Cotonou and Porto-Novo)

To determine whether there is LF transmission in Cotonou and Porto-Novo, which are the two main urban locations of Benin where the LF status is undetermined. A study will be conducted to evaluate the prevalence of LF using antigenemia and antibody testing (FTS and Wb123). An entomological survey will be implemented to understand the dynamic of LF transmission and potential barriers to LF MDA in urban settings. 

Preliminary study findings:

  • While mass drug administration (MDA) in Benin is on track to eliminate LF in most endemic cities, 50 such cities – including the country’s largest cities, Cotonou and Porto Novo – never received treatements.
  • In 2016, more than 15 years after mapping, LF endemicity was re-evaluated in Cotonou and Porto Novo to put in place adequate strategies for LF elimination. This study constituted that re-mapping effort.
  • The various surveys, conducted in vectors and humans through collection of entomological and parasitological data, reveal an absence of LF transmission in Cotonou and Porto Novo.
  • The results demonstrate that the number of cities endemic for LF in Benin has dropped from 50 to 48.
  • However, the study revealed a lack of awareness of LF by residents and health workers, highlighting the need for more education and awareness raising on the disease.
