The World Health Organization (WHO) has raised alarms over potential surges in global tuberculosis (TB) cases following significant funding cuts by the United States Agency for International Development (USAID). These reductions threaten to reverse years of progress in combating TB, particularly in low- and middle-income countries that heavily rely on U.S. support.

Historically, the U.S. has been a leading contributor to global TB control, providing approximately $200–$250 million annually through USAID. This funding accounted for about 25% of international donor contributions to TB programs. The abrupt cessation of these funds has led to widespread disruptions in essential services, including testing, treatment, and drug supply chains, particularly affecting 18 high-burden countries that depended on 89% of the expected U.S. funding for TB care.

The impact of these cuts is profound. In many high-burden TB countries, USAID-funded diagnosis and treatment services have been forced to close, leaving patients without access to necessary medications and care. This interruption not only endangers individual lives but also increases the risk of TB transmission within communities. Moreover, critical research initiatives aimed at developing shorter and more effective treatments for drug-resistant TB have been halted, impeding advancements in combating the disease.

Modeling studies predict dire consequences if these funding gaps persist. In countries highly dependent on U.S. support, TB cases could rise by up to 36%, and deaths could increase by 68% under worst-case scenarios. Across 26 high-burden countries, this could translate to an additional 10.67 million TB cases and 2.24 million deaths. These projections underscore the catastrophic potential of sustained funding cuts on global TB control efforts.

The ramifications extend beyond international borders. The United States has already observed a more than 15% annual increase in TB cases. Should this trend accelerate to 30%, domestic healthcare costs could triple by the end of the current administration, with TB-related deaths more than doubling compared to the previous term. This scenario highlights the interconnectedness of global health and the direct impact that international funding decisions can have on domestic public health.

In response to these challenges, the WHO emphasizes the urgency of securing alternative funding sources to sustain TB prevention and treatment initiatives. Without immediate action, the hard-won progress in the fight against TB is at significant risk, potentially leading to a global health crisis that could have been averted.

In conclusion, the recent USAID funding cuts pose a severe threat to global TB control efforts. The potential surge in TB cases and deaths necessitates swift and strategic action from the international community to mitigate the impact and safeguard the health of millions worldwide.
