Name one piece of information that you once thought was true, but
now know is false. Explain in detail how you determined that this
particular piece of information was false. Explain how your new
knowledge of Information Literacy will be used in your life from
now on.
Cite the piece of information you first refer in your
response.
Persons become infected with TB when they inhale droplet nuclei that contain tubercle bacilli and the bacilli begin to multiply in the small air sacs of the lungs. At this point, the person is considered to have latent TB
Tuberculosis bacteria, (Mycobacterium tuberculosis) however are transmitted through the air, not by surface contact. This means touching cannot spread the infection unless it is breathed in. Transmission occurs when a person inhales droplet nuclei containing tuberculosis
Under the microscope, the bacillus is seen as a bright red rod, while the surface that it grows on is colored blue. All bacteria that react in this way to a Ziehl-Neelsen stain are called acid-fast bacteria. The staining technique is used for the diagnosis of TB infection
Airborne precautions are required to protect against airborne transmission of infectious agents. Diseases requiring airborne precautions include, but are not limited to: Measles, Severe Acute Respiratory Syndrome (SARS), Varicella (chickenpox), and Mycobacterium tuberculosis.
What is latent TB infection? Many people who have latent TB infection never develop TB disease . In these people, the TB bacteria remain inactive for a lifetime without causing disease . But in other people, especially people who have weak immune systems, the bacteria become active, multiply, and cause TB disease
Remain in your home. Take your TB medicines, eat healthy foods, and get plenty of rest. Wear a mask that covers your nose and mouth if you must go to medical appointments and when health care providers come to your home. Cover your mouth and nose with a tissue when you cough, sneeze, or laugh.
he Mantoux tuberculin skin test is a test to check if a person has been infected with TB bacteria. How does the TST work? Using a small needle, a health care provider injects a liquid (called tuberculin) into the skin of the lower part of the arm. When injected, a small, pale bump will appear.
People at high risk for progression to TB disease once infected include: Persons with human immunodeficiency virus HIV infection. Persons who were infected with M. tuberculosis within the past 2 years, particularly infants and very young children.
