Health officials are grappling with the resurgence of tuberculosis both in the United States and globally as the disease, which was previously on the decline, is now on the rise. In a recent outbreak that started in January 2024 in Kansas City, Kansas, and spread to nearby counties, 147 individuals have been diagnosed with tuberculosis, with 67 displaying symptoms. The remaining 80 cases were latent infections, showing no immediate signs of illness.
Tuberculosis, caused by the bacterium Mycobacterium tuberculosis, has plagued humanity for thousands of years. Historical records dating back to 410-400 B.C.E. describe the disease as “phthisis,” characterized by a progressive wasting away of the body. Referred to as consumption or the white plague due to its devastating effects, tuberculosis was often fatal if left untreated.
The 19th century marked significant advancements in understanding tuberculosis. In 1865, Jean Antoine Villemin demonstrated the transmissibility of the disease from infected to healthy individuals. Subsequently, in 1882, German physician Robert Koch identified the causative agent, leading to the global recognition of World TB Day on March 24th.
Tuberculosis primarily spreads through the inhalation of infectious droplets in the air, making respiratory contact a common mode of transmission. Additionally, unpasteurized dairy products and bone grafts have been implicated in rare cases of tuberculosis transmission. The current outbreak in Kansas, which has disproportionately affected low-income communities, has raised concerns about the disease’s resurgence.
The COVID-19 pandemic has played a significant role in the recent uptick of tuberculosis cases worldwide. Disruptions in healthcare access during lockdowns, fear of contracting COVID-19, and medical supply shortages have contributed to the increase in tuberculosis incidences. Nearly 700,000 excess deaths from tuberculosis were recorded due to pandemic-related healthcare disruptions.
Treatment for tuberculosis has evolved over the years, with multidrug therapies being the current standard. Early treatments involved practices like bloodletting and consumption of cod liver oil before the advent of antibiotics in the late 1930s. Streptomycin and isoniazid were among the first antibiotics developed to combat tuberculosis, although drug resistance soon became a challenge.
In conclusion, tuberculosis remains a pressing public health concern globally, necessitating continued education, awareness, and proactive efforts to combat its spread. Early detection, timely treatment, and ongoing research are crucial in addressing the resurgence of this ancient disease and reducing its impact on communities worldwide.
