Tuberculosis (TB) is an infectious disease that primarily affects the lungs but can also target other parts of the body. It is caused by the bacteria Mycobacterium tuberculosis, which spreads through the air when an infected person coughs, sneezes, or speaks.
For centuries, tuberculosis has posed a major global health concern, but advancements in medical science and awareness have enabled effective prevention, diagnosis, and treatment of the disease.
Causes of Tuberculosis:
There are several factors that may increase a person’s predisposition to contacting tuberculosis.
Living or work conditions that may increase the risk include:
- Living in crowded or unsanitary conditions
- Living with someone with active TB disease
- Living or traveling to a country where TB is prevalent (Latin America, Africa, Asia, and Pacific Islands), and
- Working in health care treating people with a high risk of TB.
People with a weakened immune system are at an increased risk of having a TB infection progressing to an active TB disease.
The following are conditions or treatments that may weaken the immune system:
- HIV/AIDS
- Diabetes
- Severe kidney disease
- Cancer
- Malnutrition
- Drugs to prevent organ rejection
- Long-term intake of steroids
- Illegal substances.
Symptoms of Tuberculosis:
The symptoms of TB can vary depending on the type and stage of the disease. In the early stages, TB may not present any noticeable symptoms, making it difficult to detect. However, as the disease progresses, common symptoms may include persistent cough (with or without blood), chest pain, fatigue, weight loss, night sweats, fever, and chills.
If TB affects organs other than the lungs, the symptoms may differ accordingly.
Diagnosing Tuberculosis:
Early diagnosis is crucial in effectively managing and treating tuberculosis. Healthcare professionals employ various diagnostic methods to identify TB in patients.
These may include:
- Tuberculin Skin Test (TST): This test involves injecting a small amount of protein called tuberculin into the skin and observing the reaction. If a person has been exposed to the TB bacteria, their immune system will produce a response at the injection site.
- Interferon-Gamma Release Assays (IGRAs): These blood tests measure the release of interferon-gamma in response to TB-specific antigens. IGRAs exhibit greater specificity compared to TST and do not cross-react with the Bacillus Calmette-Guérin (BCG) vaccine, commonly administered for TB prevention.
- Chest X-ray: An X-ray can help identify any abnormalities in the lungs and determine if there are any signs of TB infection, such as cavities or infiltrates.
- Sputum Test: This involves analyzing a sample of sputum (phlegm) for the presence of TB bacteria. It is particularly useful in diagnosing pulmonary TB.
Once the diagnosis is confirmed, healthcare providers may conduct further tests to determine the drug.
susceptibility of the TB bacteria. This information is vital for prescribing appropriate treatment regimens.
