South Africa faces a severe TB crisis, with 280,000 cases and 54,000 deaths annually. The situation is complicated by high HIV prevalence, limited healthcare access, and medical personnel shortages. Factors such as poverty, inequality, malnutrition, smoking, and silicosis contribute to the high TB prevalence.

The AI-Assisted TB Screening Collaboration
The KwaZulu-Natal Department of Health collaborated with USAID, THINK, LTE Medical Solutions, and Qure.ai to enhance TB diagnosis using AI-augmented portable X-ray machines in mobile vans. The program screened 6,500 individuals in its first six months, identifying 187 TB cases that might have been missed. AI offers faster turnaround times, higher accuracy, and the ability to diagnose TB without radiologists.
Benefits of AI in TB Diagnosis
Digital X-ray augmented by AI allows for timely diagnosis and treatment initiation, particularly in rural areas and for HIV-positive patients. Community outreach events encourage TB screening, and AI-assisted X-rays identify asymptomatic patients in hotspot areas. Health officials are optimistic about scaling the program and expanding its use to diagnose other diseases.
