Thanks to Android technology, the GTMP was able to survey more districts in three years than had been recorded in the previous 12 years. The data collected enables ministries of health to focus their strategies to tackle trachoma using the WHO-approved SAFE strategy: surgery, antibiotics (through mass drug administration), face-washing and environmental improvements (such as sanitation).
During the project, more than 550 teams of trained surveyors, including ophthalmic nurses, visited millions of people in sample households in the most remote locations in 29 countries, including Chad, Eritrea, Pakistan, Papua New Guinea, Solomon Islands, Colombia and Yemen.
The mapping of trachoma and the legacy of the Global Trachoma Mapping Project lives on in the Tropical Data initiative, which was launched in July 2016.
Tropical Data uses the same approach and methodology as the GTMP, enabling organisations to plan, collect and analyse data about trachoma.
