TDR in 2020 published a conceptual framework that outlines the essential elements of successful multisectoral collaborations for preventing and controlling vector-borne diseases. TDR has since been supporting research teams that have been implementing the multisectoral approach (MSA), which some countries have found to have a measurable impact on transmission of diseases such as malaria.
Last month, TDR organized a workshop in Saly, Senegal, to help participants from national malaria control programmes in four African countries (Burkina Faso, Senegal, United Republic of Tanzania and Zambia) design MSA activities relevant to their local context.
The workshop included presentations from eight countries that have already been implementing the MSA. For example, China has adopted the approach for malaria elimination, and Brazil has been implementing it for dengue control. They shared experiences and case studies of joint activities implemented by multiple health-related sectors such as agriculture; mining; and water, sanitation and hygiene.
In Senegal, MSA has contributed to a substantial reduction of malaria cases in the locality of Ndayane, in the district of Popenguine. Here, the fishing sector has played an important role, as a fishermen’s association has sensitized local populations on the use of long-lasting insecticidal nets. This engagement began about 20 years ago, and only 6 malaria cases were reported for children under age 5 so far this year in this district.
“The elimination of malaria cannot be conceived without a multisectoral approach and commitment and ownership by communities,” said Dr Doudou Sene, Coordinator of Senegal’s National Malaria Control Programme. “The multisectoral approach is a powerful tool that has a real impact on reducing malaria transmission.”
Furthermore, a study in collaboration with the agriculture and environment sectors for controlling mosquitoes transmitting malaria has been conducted in the Sahel region of Mali. This included physical destruction of breeding sites, larviciding and killing swarming adult males. This has reduced almost 60% of Anopheles mosquito densities in homes in a fishing village along the Niger River over a 4-month period.
“Hearing and learning from colleagues in other countries about implementing the multisectoral approach has helped me understand which aspects work better than others as we prepare to implement MSA in Zambia,” said Dr Freddie Masaninga, WHO Country Office Representative in Zambia.
