Case Study: Cali, Colombia’s Public Health Team reduces mosquito breeding sites with Premise

Cali, Colombia reduces mosquito breeding sites by 65% with Premise

The city of Cali, Colombia's Public Health Team faced a significant challenge during a 2016 Zika outbreak, as they lacked a real-time system to manage field activities and make data-driven decisions on mosquito control. To address this, the vendor Premise was engaged through a USAID grant to design a digital solution using smartphone tasks for local residents.

Premise implemented a platform where citizens used their smartphones to complete tasks like identifying and destroying mosquito breeding sites. The data collected was visualized on real-time dashboards for health authorities. This solution led to the destruction of over 70,000 breeding sites and a 65% reduction in the average number of sites in inspected areas. Premise's work empowered the city to make evidence-based decisions and dispatch resources to high-risk areas in real time.
