Michael Levy, PhD, Professor of Epidemiology, is a co-author of a new study exploring an alternative approach to vector control for Chagas disease. Drawing inspiration from the adaptive immune system, the researchers developed a flexible, community-centered strategy and evaluated its effectiveness during an ongoing vector control campaign in Arequipa, Peru.
Vector-borne diseases kill and harm millions of people each year, while vector control campaigns help prevent many more infections. Traditionally, these strategies have been shaped by military approaches, with hierarchical structures that may be less effective in civilian settings. The study found that an alternative approach inspired by the immune system outperformed the conventional strategy in the context of Chagas disease control.
The findings highlight the importance of vector control strategies that can work across scales, adapt to changing goals and resources, and effectively engage the communities they aim to protect. The researchers propose that the immune system offers a useful model for developing more flexible and effective approaches to vector control.
