Tuberculosis (TB): Causes, Symptoms, Treatment, Prevention, and Everything You Need to Know

What Is Tuberculosis?
Tuberculosis (TB) is

a contagious bacterial infection caused by Mycobacterium tuberculosis. It primarily affects the lungs, but it can also spread to other parts of the body, including the kidneys, spine, brain, and lymph nodes. Although tuberculosis is preventable and curable, it remains a significant public health concern worldwide.
Early diagnosis and proper treatment are essential to prevent complications and stop the spread of the disease.
What Causes Tuberculosis?
Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. The infection spreads through the air when a person with active pulmonary TB coughs, sneezes, speaks, laughs, or sings. People nearby may inhale the bacteria and become infected.
However, TB does not spread through:
Shaking hands
Sharing food or drinks
Touching surfaces
Sharing clothing
Kissing briefly
Not everyone infected with TB becomes sick. Some people develop latent TB infection, where the bacteria remain inactive and cause no symptoms. Others develop active TB disease, which requires immediate medical treatment.
Symptoms of Tuberculosis
Symptoms of active TB may include:
A persistent cough lasting three weeks or longer
Chest pain
Coughing up blood or mucus
Fever
Night sweats
Unexplained weight loss
Loss of appetite
Fatigue
Chills
If TB spreads outside the lungs, symptoms depend on the affected organ.
Who Is at Risk?
Certain individuals have a higher risk of developing tuberculosis, including:
People living with weakened immune systems
Individuals with HIV infection
People with diabetes
Smokers
Older adults
Young children
People living in crowded conditions
Healthcare workers exposed to TB patients
Individuals with poor nutrition
How Is Tuberculosis Diagnosed?
Healthcare providers may use several tests to diagnose tuberculosis, including:
Tuberculin skin test (Mantoux test)
TB blood tests
Chest X-ray
Sputum examination
Molecular laboratory tests to detect TB bacteria
Prompt diagnosis helps reduce transmission and improves treatment outcomes.
Treatment for Tuberculosis
Tuberculosis is treated with a combination of antibiotics taken over several months. It is extremely important to:
Take medications exactly as prescribed.
Complete the entire course of treatment.
Attend all follow-up appointments.
Avoid stopping treatment early, even if symptoms improve.
Incomplete treatment can lead to drug-resistant tuberculosis, which is much more difficult to treat.
Can Tuberculosis Be Prevented?
Yes. You can lower your risk of TB by:
Seeking medical evaluation if you have symptoms.
Completing treatment for latent TB infection if recommended.
Ensuring good ventilation in indoor spaces.
Covering your mouth and nose when coughing or sneezing.
Wearing a mask when advised in healthcare settings.
Practicing good hand hygiene.
Receiving the BCG vaccine where it is recommended by public health authorities.
When Should You See a Doctor?
Seek medical attention if you experience:
A cough lasting more than three weeks
Coughing up blood
Persistent fever
Night sweats
Unexplained weight loss
Ongoing fatigue
Close contact with someone diagnosed with active tuberculosis
Early diagnosis protects both your health and those around you.
