Historical overview of Tuberculosis: Roots, diagnostic methods, therapeutic approaches, and additional insights
Tuberculosis (TB), an infectious disease that primarily attacks the lungs, has a long and complex history in North America. Evidence suggests that the disease existed in the Americas as early as antiquity, with some genetic studies indicating TB-like bacteria were present around AD 140 [3]. However, it was during the European colonization and urbanization periods that TB became widespread in North America.
The major spread of TB in North America accelerated from the 1600s-1700s, reaching near-epidemic proportions by the 18th and 19th centuries. The industrial revolution and urban crowding during this period dramatically increased infection rates in North American cities, leading to widespread outbreaks and high death tolls [1][2].
The airborne spread of TB, primarily by coughing of infected individuals, allowed it to proliferate in crowded, industrializing cities across Europe and North America. Poor hygiene and dense population conditions further facilitated its transmission [2]. In the United States, specific public health data show high mortality rates due to TB in cities like New York and New Orleans during the 19th century [1].
The scientific understanding of TB's contagious nature and causative agent developed in the late 19th century. In 1882, Dr. Robert Koch discovered the bacterium that causes TB, Mycobacterium tuberculosis [4]. This discovery was a significant milestone in controlling the spread of the disease.
Today, TB treatment consists of antibiotics, with the most common antibiotic medication for latent TB infection being isoniazid (INH) [5]. For active TB disease, the most common treatment involves a combination of INH, rifampin, pyrazinamide, and ethambutol, which a person typically takes for 6-12 months [6].
It's important to note that not everyone with a latent TB infection will develop active TB disease. The original human infection of TB dates back about 6,000 years, with the disease known by various names such as phthisis in ancient Greece, tabes in ancient Rome, schachepheth in ancient Hebrew, the white plague in the 1700s, and consumption in the 1800s [7].
The Bacille Calmette-Guerin (BCG) vaccine, the first tuberculosis vaccine, was first developed by Albert Calmette and Jean-Marie Camille Guerin in 1908 [8]. However, the BCG vaccine is not always effective in preventing infections. People who are at higher risk of developing active TB include older adults, infants, people with HIV, and those who are close to people who have active TB or living in an area of the world with a high infection rate [9].
In conclusion, the spread of tuberculosis to North America was a gradual process involving early human presence with TB-like bacteria, followed by a huge amplification during European settlement and urbanization starting mainly in the 18th and 19th centuries. Understanding the history and spread of TB is crucial for developing effective prevention and control strategies today.
