Pulmonary tuberculosis, also known as TB, is a contagious infection that primarily affects the lungs. It is a disease that can remain dormant in the body and may only show symptoms later in life. Shockingly, it is estimated that almost one-third of the global population is infected with some form of pulmonary tuberculosis. Although not always fatal, this disease poses a significant risk to the respiratory system and requires a rigorous antibiotic treatment regimen. Unfortunately, the increasing resistance to antibiotics is making the treatment of pulmonary tuberculosis more challenging.
Understanding Tuberculosis
Tuberculosis (TB) is a contagious disease that is primarily spread through inhaling small droplets expelled by an infected person. In the past, tuberculosis wards were established to isolate individuals with the illness, as part of public health measures to safeguard the community. Although TB primarily affects the lungs, it can also impact other areas of the body such as the abdomen, nervous system, bones, and glands. The specific bacteria responsible for causing tuberculosis is known as Mycobacterium tuberculosis. It is important to note that while TB can be transmitted through the air, it does not survive on surfaces. Therefore, it is not possible to contract the disease through casual contact such as handshakes or sharing food and drinks.
Symptoms of Tuberculosis
Tuberculosis (TB) can present with different symptoms depending on whether it is in its latent or active form. Active TB is characterized by distinct signs that may indicate the presence of the disease. These symptoms include:
- Persistent cough: Individuals with active TB often have a chronic cough that produces a significant amount of phlegm. In some cases, blood may be present in the sputum.
- Weight loss and lack of appetite: TB can cause unintentional weight loss and a decrease in appetite.
- Persistent fever: A prolonged fever is a common symptom of active TB.
- Fatigue and tiredness: TB can lead to a persistent feeling of tiredness and fatigue.
- Night sweats: Many individuals with active TB experience excessive sweating, particularly during sleep.
- Breathlessness: Pulmonary tuberculosis, which affects the lungs, can cause breathlessness that gradually worsens over time.
- Chest pain: Both scarring and active disease can contribute to chest pain in individuals with TB. Constant coughing may also be a factor.
- Less prominent symptoms: In addition to the more common symptoms mentioned above, individuals with TB may also experience abdominal pain, headaches, and confusion, although these symptoms are less common.
If you suspect you may have TB or are experiencing any of these symptoms, it is important to seek medical attention for proper diagnosis and treatment.
