In 2023, Breakthrough ACTION and Guyana’s Ministry of Health refined the 'Lil Mosquito, Big Problem' malaria campaign using human-centred design. Phase II introduced peer-led videos (Miners' Buzz), community champions, incentives for volunteer testers and a transport network to improve supply delivery. These efforts enhanced engagement, coordination and timely reporting, reaching over 7,800 people. The campaign's innovative, community-driven approach has improved malaria prevention in remote mining regions. Accessed on 20/06/2025.
