The device targets community health workers, nurses, and pharmacists in settings without x-ray infrastructure or specialist clinicians. Funding came from The Steele Foundation for Hope, iFSP Group, Global Innovation Fund, and existing backers. The capital will support clinical research, hardware and AI model development, and expansion across sub-Saharan Africa and parts of Asia. South Africa reported 249,000 TB cases and 54,000 deaths in 2024, with 58% of positive cases showing no symptoms, highlighting the need for non-symptom-based screening tools. ## Full article daily.dev links to this article rather than hosting it.
