WHAT IS TUBERCULOSIS?Tuberculosis, commonly known as TB, is a bacterial infection that can spread through the lymph nodes and bloodstream to any organ in your body. It is most often found in the lungs. Most people who are exposed to TB never develop symptoms because the bacteria can live in an inactive form in the body. But if the immune system weakens, such as in people withHIVor elderly adults, TB bacteria can become active. In their active state, TB bacteria cause death of tissue in the organs they infect. Active TB disease can be fatal if left untreated. Because the bacteria that cause tuberculosis are transmitted through the air, the disease can be contagious.

TUBERCULOSIS BACTERIA


BY WHICH MICRO-ORGANISM IS TUBERCULOSIS CAUSED?Tuberculosis (TB) is an infectious disease that is caused by abacteriumcalledMycobacterumtuberculosis (Mtb). When a person breathes inMtb-contaminated air, the inhaled TB bacteria reach the lungs. This causes anMtbinfection. However, not everyone infected with TB bacteria becomes sick. The bacteria can remain dormant (asleep) for years and not cause any TB disease

For someone to develop active TB disease, the following two events must take place:The bacteria enter the body and cause anMtbinfection.The immune system cannot stop the TB bacteria from growing and spreading after the initial infection.The active bacteria multiply and destroy the tissue. A person with TB disease shows symptoms that vary, depending on where the TB bacteria are growing. In most cases, the bacteria attack the lungs.


BACTERIA BY WHICH TB IS CAUSED.


EFFECTS OF TUBERCULOSISMajor symptoms of TB are: prolonged cough, bloody expectorations, chest pain, and changes in a person's general health status. Coughing, sneezing, talking, and spitting can all spread the bacilli into the air, where they can remain viable for several hours before being inhaled by another person.

CURE OF THE THREATENING DISEASE.Infection ControlHospitals and clinics should take precautions to prevent the spread of TB, which include identifying patients with suspected TB and using ultraviolet light to sterilize the air, special filters, and special respirators and masks. In hospitals, people with TB SHOULD BE isolated in special rooms with controlled ventilation and airflow until they can no longer spread TB bacteria. By having an infection control plan in place, healthcare settings can ensure the prompt detection and treatment of persons who have suspected or confirmed TB disease.
