Los Angeles County faces an alarming rise in tuberculosis (TB) cases, marking the highest count since 2016. This concerning surge, combined with critical cuts to public health funding, threatens to reverse years of hard-won progress against a disease that is both preventable and curable. As the world marked World TB Day on March 24, 2026, the local crisis in L.A. County underscores a worrying global trend where vital health programs are jeopardized by diminishing resources, potentially leading to more undetected infections, wider community spread, and increased severe illness.
L.A. County’s Alarming TB Resurgence
The Los Angeles County Department of Public Health recently released its 2025 TB surveillance report, revealing a significant 3.4% increase in cases over the past year. This uptick brings the total to 554 confirmed cases, painting a stark picture of a growing public health challenge. Officials are sounding the alarm: without sustained investment in early detection, treatment, and robust support systems, this resurgence could dismantle the progress made in controlling TB.
Tuberculosis, caused by the bacterium Mycobacterium tuberculosis, spreads silently through the air. When an infected individual coughs, speaks, or breathes, tiny droplets can transmit the disease. Many people may not feel sick initially, becoming unwitting carriers who unknowingly spread the infection. The bacteria can also lie dormant, or latent, for years before developing into an active, contagious, and life-threatening illness. This silent spread makes the disease particularly insidious and challenging to contain, emphasizing the critical need for constant vigilance and accessible healthcare.
The Threat of Underfunded Public Health
The escalating TB cases in Los Angeles County are exacerbated by ongoing funding cuts to public health initiatives. This mirrors a broader national and global pattern where essential programs, designed to prevent and treat infectious diseases, are under severe strain. Just as New York City has seen a concerning resurgence in HIV infections linked to pandemic disruptions and structural inequalities, L.A. County’s battle against TB is now facing similar headwinds. A well-funded public health infrastructure is the frontline defense against such diseases.
Globally, the situation is even more dire. The World Health Organization (WHO) has issued stark warnings about a potential worldwide surge in TB cases and deaths. This global crisis is largely attributed to significant funding reductions, such as those implemented against the U.S. Agency for International Development (USAID) which previously contributed a quarter of all international donor funding for TB. These cuts have led to the collapse of drug supply chains, disruption of laboratory services, and the breakdown of surveillance systems in many high-burden countries. The U.S. itself recorded over 9,600 TB cases in 2023, a nearly 16% increase from the previous year, highlighting that infectious diseases know no borders and local issues can quickly become global concerns.
The Dire Consequences of Delayed Care
Effective TB treatment requires months of consistent care and medication. When this care is delayed or interrupted, the consequences are severe for individuals and the community alike. Infected individuals remain infectious for longer periods, increasing the risk of transmission. More cases go undetected, allowing the disease to spread further into communities, particularly in indoor spaces or areas where TB is already prevalent. The infection also becomes more severe and much harder to treat, leading to prolonged suffering and increased healthcare costs.
Without robust investment in early detection, comprehensive treatment, and patient support, these risks magnify exponentially. Individuals with underlying health conditions, such as diabetes, are particularly vulnerable to developing severe illness after exposure. Dr. Barbara Ferrer, Director of the Los Angeles County Department of Public Health, rightly points out that “Tuberculosis is a disease of inequity that thrives in the shadows of poverty and housing instability.” Every dollar cut from the budget directly impacts the most vulnerable, threatening not only their lives but also the broader health and safety of the entire community. Preventing TB cases today directly avoids costly hospitalizations and future outbreaks.
L.A. Public Health’s Vital Efforts
Despite the challenging budgetary climate, the Los Angeles County Department of Public Health remains committed to combating TB. Their multifaceted approach includes:
Disease Tracking: Early detection of risks and prevention of outbreaks through diligent surveillance.
Clinical Guidance: Providing expert clinical advice, care coordination, and comprehensive case management for patients.
Contact Tracing: Conducting thorough contact investigations and implementing rapid outbreak responses to contain spread.
Patient Support: Offering crucial housing and nutritional assistance to help individuals complete their often months-long treatment regimens.
In 2025 alone, these vital efforts included providing over 4,200 nights of housing and more than 3,000 grocery and gas vouchers. These services are absolutely essential for preventing the spread of TB and are at risk without sustained funding. In a proactive move, and despite fiscal uncertainty, Public Health launched the Southern California Regional Community of Practice to End TB in 2025. This initiative provides essential training and guidance to community healthcare providers, significantly expanding local capacity for TB testing and treatment across L.A. County.
A Community-Wide Call to Action
The fight against TB requires a collective effort. To symbolize this shared commitment, several prominent Los Angeles County landmarks, including Los Angeles City Hall and Union Station, were illuminated in red on World TB Day. This visual reminder underscores the urgency of the situation and the importance of community engagement.
Public Health strongly urges individuals at higher risk to speak with their healthcare providers about TB testing. This includes people born in or who have recently traveled to regions where TB is more common, as well as those with compromised immune systems. Early detection and prompt treatment are paramount not only for protecting individual health but also for effectively preventing the spread of TB throughout our communities. For those without access to healthcare services, TB testing and follow-up care are readily available at six Public Health centers throughout L.A. County. These accessible resources are vital in ensuring that financial barriers do not prevent life-saving care.
Global Health Parallels: Investment is Key
The challenges faced by L.A. County in its TB control efforts are not isolated. The resurgence of “forgotten diseases” like syphilis globally, as highlighted by researchers at the Wellcome Sanger Institute, demonstrates how easily progress can be undone without sustained vigilance and funding for research, prevention, and diagnostics. Similarly, the ongoing crisis of violence against women, despite clear evidence of effective prevention strategies, suffers from collapsing funding, illustrating a broader neglect of critical human rights and public health issues. These examples underscore a universal truth: sustained investment in public health infrastructure and preventative programs is the bedrock of societal well-being. The erosion of these investments, whether local or global, inevitably leads to a resurgence of preventable suffering and increased societal costs.
Frequently Asked Questions
What caused the recent rise in TB cases in Los Angeles County?
The Los Angeles County Department of Public Health’s 2025 surveillance report shows a 3.4% increase in TB cases over the past year, reaching 554 cases. This increase is primarily attributed to a combination of factors, including the silent, airborne spread of the disease, and crucially, cuts to sustained public health funding. Reduced funding can lead to fewer undetected cases, delayed treatment, and an increased risk of community transmission, reversing hard-won progress against this preventable and curable illness.
Where can individuals in Los Angeles County get tested for TB if they lack healthcare access?
For individuals without access to regular healthcare services, TB testing and follow-up care are available at six Public Health centers located across Los Angeles County. These centers provide essential services to ensure that all residents, regardless of their insurance status or ability to pay, can access crucial testing and treatment. Details for these clinics can be found on the L.A. County Public Health website.
What are the broader implications of funding cuts on infectious disease control, like TB, in communities like L.A.?
Funding cuts significantly jeopardize infectious disease control by hindering essential services. This includes disrupting surveillance systems for early detection, limiting access to clinical guidance and case management, and reducing vital patient support like housing and nutritional assistance that ensures treatment completion. Globally, similar cuts have led to collapsing drug supply chains and laboratory services, as seen with USAID’s reductions affecting TB programs worldwide. These reductions not only increase local community spread but also make the U.S. more vulnerable to global outbreaks, as infectious diseases recognize no borders.
The Path Forward: Sustained Investment
The rising TB cases in Los Angeles County serve as an urgent warning that public health achievements are fragile and require continuous, dedicated investment. The proactive measures taken by the L.A. County Department of Public Health, even amidst budgetary constraints, demonstrate a deep commitment to community well-being. However, these efforts cannot succeed in isolation. A sustained, holistic approach that prioritizes funding for early detection, comprehensive treatment, and patient support is essential. By learning from both local challenges and global health parallels, L.A. County can reinforce its defenses against TB and protect the health of all its residents, ensuring that a preventable disease does not become an uncontrolled crisis.
