Climate change is emerging as a powerful force that could significantly intensify the factors fueling tuberculosis (TB), which remains the deadliest infectious disease caused by a single pathogen worldwide. Yet, despite its severity, TB tends to be overlooked in broader discussions about the health impacts of climate change. Recognizing this gap, the World Health Organization has commissioned the development of a comprehensive analytical framework designed to map out possible causal links between a warming planet and the spread of TB.
This effort culminated in a detailed position paper published in The Lancet Respiratory Medicine. The paper not only describes how the framework was constructed but also compares it with existing evidence, highlighting key areas where knowledge is still scarce—especially regarding how climate change influences TB transmission and outcomes. Additionally, it points out potential opportunities for intervention and policy action, encouraging a more integrated approach to tackling TB in the context of environmental change.
