Health officials are raising alarms as tuberculosis (TB)—often referred to as the “white plague”—sees a noteworthy resurgence across the United States. This uptick follows a significant downturn in 2020, a decline attributed largely to disruptions in routine screenings and diagnoses during the COVID-19 pandemic.
### Rising TB Cases and Context
In 2024, the Centers for Disease Control and Prevention (CDC) reported over 10,600 confirmed cases of TB, marking a rise for the third consecutive year. This figure translates to approximately three cases per 100,000 individuals, the highest annual tally since 2013. Despite this increase, rates in the U.S. remain relatively low when compared to global averages; the World Health Organization (WHO) estimates about 131 cases per 100,000 worldwide—nearly 40 times higher than the U.S. rate.
TB, a treatable bacterial infection predominantly affecting the lungs but capable of targeting other organs, is transmitted through airborne particles when an infected person coughs, speaks, or sneezes. According to Dr. Renuga Vivekanandan, a professor at Creighton University and Chief Medical Officer at CHI Health Physician Enterprise Midwest, the recent rise in cases is both alarming and anticipated. “The COVID-19 pandemic effectively disrupted TB surveillance and treatment programs across the country,” she stated, noting that latent TB infections that went untreated during the pandemic are now activating into more serious conditions.
### The Impact of Pandemic Disruptions
The pandemic severely affected local and state public health programs, leading to staffing shortages that have yet to be resolved. This reduction in capacity has posed challenges in managing TB and other infectious diseases. Dr. Vivekanandan emphasized that the return of international travel and increased migration from TB-endemic regions contribute to the current situation. “What we’re seeing now is largely a rebound effect,” she explained, referring to the latent infections that are becoming active.
Individuals at high risk—those born in or frequently traveling to areas with high TB prevalence, immunocompromised persons, and those living in overcrowded conditions—are particularly advised to consult healthcare providers about TB screening and prevention.
### Symptoms and Health Consequences
Approximately 25% of the U.S. population has been infected with TB bacteria, though only 5-10% of those infected will develop active disease. Symptoms of active TB include persistent cough, chest pain, fatigue, weight loss, and fever. In severe cases, patients may cough up blood, necessitating immediate medical attention. Notably, active TB poses a greater public health risk as it is contagious, while individuals with latent TB—who exhibit no symptoms—are not able to spread the infection.
Dr. Masae Kawamura, a former TB control director in San Francisco, pointed out the dangers of misinterpreting mild TB symptoms. “Often, there are minimal symptoms for a long time, and people mistake their occasional cough for allergies, smoking, or a cold they can’t shake off,” she said.
### Prevention and Treatment Protocols
Fortunately, TB is a preventable and treatable disease. Medical experts recommend various precautionary measures and treatment protocols, particularly for at-risk populations. Individuals who fall into vulnerable categories, such as those with diabetes, malnutrition, or excessive alcohol or tobacco use, should undergo regular screening.
Testing typically involves skin or blood tests to identify latent infections, followed by imaging or sputum analysis to confirm active disease. Treatment regimens consist of antibiotics, commonly including isoniazid and rifampicin, administered daily for four to six months. Failing to complete medication courses can lead to drug-resistant strains of TB, complicating treatment and recovery.
The economic impact of rising TB cases is also noteworthy, as healthcare systems grapple with increased patient loads and associated treatment costs. Untreated TB has a mortality rate of nearly 50%, underscoring the imperative for effective prevention and intervention strategies.
### Conclusion
As tuberculosis cases continue to rise post-pandemic, public health officials stress the importance of vigilance, screening, and education regarding the disease. Identifying and treating latent TB infections remains crucial for halting the disease’s advancement and ensuring community health. The CDC’s recommendations to focus on higher-risk populations, rather than the general public, aim to optimize available resources in combating this potentially deadly condition.
Efforts to revamp TB treatment programs and enhance public awareness are essential steps toward effectively addressing the resurgence of this historic illness.
