What is Tuberculosis?
Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs, but can also affect other parts of the body such as the kidneys, spine, and brain.
TB spreads through the air when an infected person coughs, sneezes, or speaks. It is highly contagious and can be transmitted to people in close contact. However, not everyone infected with TB bacteria becomes sick. Some individuals have a latent TB infection, where the bacteria are present in their body but are not actively causing illness. These individuals do not experience symptoms and are not contagious.
On the other hand, active TB disease occurs when the bacteria multiply and cause symptoms. Common symptoms include persistent cough, chest pain, fatigue, weight loss, fever, and night sweats. If left untreated, TB can be life-threatening.
Tuberculosis can be diagnosed through laboratory tests, such as a chest X-ray, sputum culture, or a tuberculin skin test. Treatment usually involves a combination of antibiotics taken over a period of several months to ensure that all bacteria are eliminated.
To prevent the spread of tuberculosis, it is important to identify and treat infected individuals promptly. This can be achieved through contact tracing, screening high-risk populations, and providing adequate treatment and support to those affected. Additionally, measures such as proper ventilation and respiratory hygiene can help reduce the transmission of TB.

Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs but can also infect other parts of the body such as the kidneys, bones, and brain. TB is spread through the air when an infected person coughs, sneezes, or talks, releasing tiny droplets containing the bacteria.
Common symptoms of TB include coughing (sometimes with blood), chest pain, fatigue, weight loss, night sweats, and fever. However, some individuals, especially those with weakened immune systems, may not exhibit any symptoms.
TB can be treated with a combination of antibiotics for a specified duration. It is important to complete the full course of medication to ensure that all bacteria are eradicated and to prevent the development of drug-resistant strains. Preventive measures, such as the Bacillus Calmette-Guérin (BCG) vaccine and improving indoor ventilation, are also used to control the spread of TB.
Despite progress in treatment and prevention, TB remains a significant global health challenge. It is estimated that around 10 million people become ill with TB every year, and approximately 1.4 million die from the disease. TB is particularly prevalent in low-income countries, crowded areas, and among individuals with compromised immune systems, such as those with HIV/AIDS.
Efforts to combat TB involve early detection through diagnostic tests, improving access to effective treatment, and promoting public awareness to reduce the stigma associated with the disease. It requires close collaboration between governments, healthcare providers, and international organizations to effectively address the burden of tuberculosis globally.

Tuberculosis (TB) is an infectious disease caused by the bacteria Mycobacterium tuberculosis. It primarily affects the lungs but can also affect other parts of the body, such as the kidneys, spine, and brain. TB spreads through the air when an infected person coughs, sneezes, or talks, and another person inhales the bacteria.
Symptoms of TB include persistent cough with blood-tinged sputum, fatigue, weight loss, fever, night sweats, and chest pain. However, not everyone infected with TB bacteria develops active TB disease. In some cases, the bacteria remain dormant in the body and do not cause any symptoms. This is known as latent TB, which can become active if the immune system weakens.
TB can be diagnosed through various tests, including a skin test, blood test, sputum test, or imaging tests like chest X-ray. Treatment typically involves a combination of antibiotics taken over several months. It is essential to complete the entire course of medication to ensure complete eradication of the bacteria and prevent the development of drug-resistant strains.
Preventing the spread of TB involves identifying and treating active cases, as well as providing preventive therapy for individuals with latent TB. Good respiratory hygiene, such as covering the mouth and nose when coughing or sneezing, and proper ventilation in crowded settings, can also help reduce transmission.
TB is a global public health issue, with the highest burden in low- and middle-income countries. However, it can affect anyone, regardless of socioeconomic status or geographic location. Efforts to control and eliminate TB include improving access to diagnosis and treatment, developing new diagnostic tools and vaccines, and addressing social determinants of the disease’s spread, such as poverty and malnutrition.
