Help with MapSwipe projects in Chad!

ℹ️ MSF currently has two priority MapSwipe campaigns in Chad and aims to complete them before the end of June. More projects are in draft, so every swipe counts!

ℹ️ In Chad, MSF provides medical care and assistance to displaced people and local communities, who often face food insecurity. The teams are working to prevent and respond to seasonal peaks of malnutrition and malaria in children, and are also carrying out vaccination campaigns.

Thank yout!⭐
