The correct answer is: Tuberculosis (TB)

The leading cause of death from infectious diseases worldwide is Tuberculosis (TB). This disease is caused by the bacterium Mycobacterium tuberculosis, which primarily affects the lungs but can spread to other parts of the body. TB is highly contagious and spreads through the air when an infected person coughs or sneezes. Despite advances in medicine and public health, TB remains a significant global health challenge, particularly in low- and middle-income countries where access to healthcare and treatment may be limited. The World Health Organization has classified TB as a major public health concern, emphasizing the need for ongoing efforts for prevention, diagnosis, and treatment. Understanding the prevalence of TB is crucial for comprehending global health patterns, as it highlights the importance of vaccination, early detection, and effective treatment strategies. This awareness is essential for dental professionals as well, who may encounter patients with TB and need to apply appropriate infection control measures to protect themselves and their other patients.
