Tuberculosis: A Global Health Challenge
Overview
Tuberculosis (TB) is a significant bacterial infection that primarily targets the lungs, but it can also impact the central nervous, lymphatic, circulatory, genitourinary systems, as well as bones and joints.
Global Impact
TB ranks as the most prevalent major infectious disease today, affecting approximately two billion people, nearly one-third of the global population. Each year, there are nine million new cases with two million resulting deaths, predominantly in developing countries.
Asymptomatic Infections
About 90% of those infected carry an asymptomatic latent TB infection (LTBI). While most do not immediately develop active tuberculosis, there is a 10% lifetime risk of progression to active TB. If untreated, more than half of these active cases can be fatal, making tuberculosis one of the top three deadliest infectious diseases worldwide, alongside HIV/AIDS and malaria.
Causes and Transmission
TB is caused by a slow-growing aerobic bacterium that takes 16 to 20 hours to divide, much slower than most bacteria, which divide in minutes.
Treatment and Diagnosis
TB symptoms can fluctuate in many patients. Effective treatment with appropriate antibiotics kills the bacteria and facilitates healing. Affected areas often become scarred over time. Diagnosing TB requires a thorough medical evaluation, including a medical history, physical exam, tuberculin skin test, serological test, chest X-ray, and microbiologic smears and cultures. Although extensive, these procedures are crucial given the serious statistics.
In conclusion, tuberculosis remains a critical health issue demanding comprehensive diagnosis and treatment to reduce its devastating impact globally.
