Tuberculosis, MTB or tuberculosis is a common and in many cases fatal infectious disease caused by various stains of mycobacterium, usually – Mycobacterium Tuberculosis. (Behera, 2010). Tuberculosis is spread from one person to another by speaking, sneezing, coughing or singing. When contact with one of the mentioned transmissions occurs, a person may be at risk of contracting this disease (bacteria) that attacks the lungs. A lung attack occurs when the person breathes air, then bacteria enters. The human body can consume bacteria that cause tuberculosis. Our immune system can usually prevent disease. For this reason, doctors distinguish between latent tuberculosis and active tuberculosis. The signs and symptoms of active tuberculosis are:1) Unintentional 4) Chills 7) Fever 2) Weight loss 5) Loss of appetite 3) Night sweats 6) Fever A healthy immune system can often fight off tuberculosis bacteria, but if the defense of the immune system is low the support is not effective. (WHO, 2012). In this article I will discuss and apply knowledge of individuals affected by the communicable infectious disease known as tuberculosis. Registered professional nurses play an important role in infection control and prevention. In this article I will state the importance of the role of professional nurses in infection and control and also apply the findings of evidence-based practice to patients with infectious and communicable diseases. Breaking the chain: the patient with an infectious disease (tuberculosis) Tuberculosis (TB) is one of the best-known infectious diseases caused by a bacterium called Mycobacterium Tuberculosis that affects the lungs and can affect any age.
