Chad had an estimated population of 19.3 million in 2023. Around 27,000 individuals developed tuberculosis (TB), and 5,800 died as a result. Despite ongoing national efforts, approximately 11,228 cases remained undiagnosed or unreported, highlighting a persistent gap in detection.
Delft Imaging has been a long-term partner of the United Nations Office for Project Services (UNOPS). Various mobile clinics of Delft Imaging have been included in the UNOPS catalogue, UN Web Buy Plus.
In 2021, the Ministère de la Santé Publique et de la Solidarité Nationale procured one mobile tuberculosis X-ray clinic (OneStopTB clinic) through the UN Web Buy Plus platform. The TB mobile screening clinic was a Double Cabin, 4×4 clinic supporting nationwide tuberculosis screening. The necessary installation and training services were provided in-country as part of the project.
Making a Difference
Webinar insights
During the 2025 Delft Imaging webinar “AI for TB Screening in Francophone Africa: Challenges, Opportunities and Impact,” Dr. Oumar Abdelhadi, Coordinating Physician of Chad’s National Tuberculosis Control Program (PNT), shared insights on the country’s efforts to improve TB detection among hard-to-reach populations using mobile digital X-ray systems with AI-enabled CAD4TB. To address access gaps, Chad deployed a mobile screening strategy targeting nomadic groups, detention centers, and refugee camps. Between 2024 and early 2025, more than 7,100 individuals were screened, resulting in 112 confirmed TB cases. “There was a real improvement in access to TB screening and diagnosis for vulnerable populations through AI,” said Dr. Abdelhadi. These innovations are advancing Chad’s strategy to reduce missed TB cases and strengthen equity in healthcare.
