In June 2019, the MadEx team travelled to the Marolambo District to continue their work reducing the burden of disease caused by schistosomiasis (bilharzia).  This year’s team was made up of doctors, medical students and a biologist (7 UK team members and 5 Malagasy team members) and we worked very closely with CEMES.

MadEx (Madagascar Medical Expeditions) has been working hard for the last 5 years to try to reduce the disease burden of schistosomiasis and soil-transmitted helminths (STHs) amongst children in the district.

Every year, the team determines the prevalence of schistosomiasis and STHs, and the effect that these parasitic diseases are having on children in villages along the Nosivolo River.  MadEx works with CEMES, local community members and the Ministry of Health in Madagascar to deliver education programmes about the parasites and to deliver mass drug administration. 


Schistosomiasis is a chronic disease with potentially life-threatening complications.  The MadEx team has seen a significant reduction in the burden of infection amongst the children over the five years that we have been working in the district.  This is vital to improve the health of the population and reduce the complications and deaths caused by these parasitic diseases.

MadEx is a voluntary organisation that relies on donations to continue and we would like to thank all who have helped us carry out this work.  We hope to continue our work with the Marolambo District for a number of years to come.
