Tropical Data
This large-scale project uses smartphone technology to gather data as part of the global fight to eliminate trachoma.
Tropical Data is a data-collection initiative that helps countries carry out surveys as they work towards eliminating trachoma.
It uses the same approach and technology as the Global Trachoma Mapping Project. More than 1,900 surveys in more than 40 countries have already taken place, and more than 6 million people across four continents have been examined.
Working in some of the most remote and difficult environments, the service helps countries to collect high-quality, standardised data, and there are plans to extend the service to support other neglected tropical diseases.
The Tropical Data website
The main website contains further information and resources, and enables programmes to request a survey and manage their data.

How does the project work?
Smartphone technology is just one aspect of the service. Data is sent from the field to the secure cloud-based server, where a data team works with health ministry staff to clean, analyse and approve the data, much faster than previous paper-based surveys. The service also provides epidemiological support to countries to develop their surveys, and a globally standardised training system.
With the evidence generated by the Tropical Data project, ministries of health are able to pinpoint exactly where to run trachoma treatment programmes and offer life-changing support. It also highlights where treatment programmes are no longer needed because interventions have been a success. Crucially, this helps countries gather evidence for the World Health Organization to show where they are free from the disease, so trachoma elimination can be declared.
Tropical Data is run by a consortium of partners including the International Trachoma Initiative (ITI), the London School of Hygiene and Tropical Medicine, RTI International and Sightsavers. It is made possible thanks to the support of governments in endemic countries, plus UK aid, USAID and The Queen Elizabeth Diamond Jubilee Trust.
