Consumers benefit from reduced disease transmission risk, lower healthcare costs from preventive municipal action, and decreased absenteeism. Households in affected regions face lower medical expenses and improved quality of life.
U.S. municipalities may adopt Belém's coordinated approach, potentially increasing public health budgets for vector control. This could drive demand for pest management services, surveillance technology, and preventive infrastructure. Federal health agencies may establish new guidelines for dengue preparedness.
