Transcript of Tuberculosis

Mycobacterium Tuberculosis
Scientific Name of Disease:
Common Name of Disease:
Tuberculosis
Multidrug Resistant Tuberculosis (MDR)
Extensive drug resistant Tuberculosis (XDR) or (XXDR)
Koch's Disease
Wasting Disease
Consumption
Transmission
Suseptible Populations
Course of Disease
No infection
Also the bacteria can get into
the lymph system into the blood
stream and infect the kindeys and
vascular skeletal areas which also have
a high oxygen content.
Latent Phase considered TB infection
but no active symptoms and is not
contagious.
Immune System Weakend
Liquifaction of the Ghon Complex and release of bacteria
active infection occurs with symptoms. At this point contagious to others.
Positive result for skin test
Symptoms
Cough Possible blood streaked sputum
Fatigue
Anorexia
Weight Loss
Low Grade Fever
Sweating and Chills
Dull aching in chest
Fact: In 2006 it was estimated that 1.7 million people died of Tuberculosis which is equal to
about 4,700 deaths per day.
Predicted that every TB case that develops into
active infection will affect 10-15 people or more.
Diagnosis
1. When injected with the tuberculin, an elevation site called a wheel forms.
2. The patient returns after 48 hours and the site is checked for induration.
a. 0-4 mm HIV with immune suppression and likelihood of infection is high. Also positive if from a high TB prevalent area, have an abnormal chest x-ray, or closely exposed to an infectious case.
b. 5-9 mm for HIV infection, a child suspected of the disease, abnormal chest x-ray, or immune suppression.
c. 10 mm or more is positive in all other situations.
Skin Test- Mantoux
X-Ray Analysis
Sputum Analysis
Treatment
Prevention
World TB day takes place
each year on March 24th
First Line Drugs:
Isoniazid
Rifampin
Ethambutol
Pyrazimanide
MDR
Second Line Drugs
XDR and XXDR
DOT programs
Development of an Effective Vaccine
Isolating the infected individuals
Public Health Education
Finding those with latent infection and treatment
Faster Treatment options/ less vigorous
