SAM PHOTO


SAM Photo® Diagnosis App is a mobile application developed by Action Against Hunger to detect severe acute malnutrition (SAM). It uses morphometric analysis of the body to diagnose the nutritional status of children under five years of age with a single photo of their left arm, enabling rapid and reliable identification of malnutrition and facilitating rapid access to the necessary treatment.
 

How does it work?

The process is intuitive. A person takes a photo of the child's left arm, without the need for an internet connection. The application evaluates the image, determining nutritional status through a previously validated algorithm. Once analysed, the photograph is automatically deleted, and if there is an Internet connection, the anonymous data is stored in a database that constantly improves the algorithm and provides highly useful information for public health systems. Finally, the user receives detailed information about treatment options in their area.

 

Geographical scope

Currently, SAM Photo is present in the following countries:

África

  • Senegal. It is the first place where we have developed and tested the SAM Photo App technology in real cases. It is the country where we have generated scientific evidence that supports the methodology we use. In Senegal, we work in the Matam region, bordering Mauritania, located in the Senegalese Sahel.
  • Uganda. It is the second African country to join the portfolio and the first in East Africa. where SAM Photo App will be tested for the first time in the context of a displacement camp. Our foray into this field is in coordination with UNHCR.
  • Mauritania. It is the most recent country to join the partnership and the second in the Sahel region. The project is expected to be developed towards the south-east of the country, an area at high risk of food insecurity and malnutrition.

Latin America

  • Guatemala. In this context, in addition to continuing to explore the influence of phenotypic differences on the accuracy of our diagnostic method for acute malnutrition, we have  further explored the study of chronic malnutrition.

Southeast Asia

  • India. It is the first Asian country to join SAM Photo App’s global portfolio. In addition to being one of the most populous countries in the world, the rate of malnutrition is  proportional to the size of the population. The introduction of SAM Photo App in this context on an operational basis will be of great benefit to the National Response to Child Malnutrition.
