Nutritional interventions for TB: a critical component of integrated TB care amid funding challenges

Undernutrition remains a leading driver of TB worldwide. Modeling and epidemiologic evidence show that nutritional interventions are highly cost-effective for reducing TB incidence and mortality, with benefits that extend beyond TB. Recent funding cuts and reprioritization threaten the availability of nutritional support and may hinder TB control efforts. We outline two approaches to sustain integrated support. First, countries can expand domestic financing through innovative mechanisms, such as taxes on tobacco and calorie-dense, low-nutrition foods. Second, governments should strengthen collaboration with international agencies to provide coordinated nutritional assistance and fill critical gaps in support for affected households.
