Tuberculosis Program Flashcards
an infectious disease caused by a type of bacteria called Mycobacterium tuberculosis.
TUBERCULOSIS
TB that affects the lungs
PULMONARY TUBERCULOSIS
TB that affects other organ
EXTRA-PULMONARY TUBERCULOSIS
Stages of TB
- EXPOSURE
- LATENT
- (ACTIVE) TB DISEASE
This happens when a person has been in contact
with, or exposed to, another person who has TB. The exposed
person will have a negative skin test, a normal chest X-ray,
and no signs or symptoms of the disease.
EXPOSURE
This happens when a person has TB
bacteria in his or her body, but does not have symptoms of the
disease. The infected person’s immune system walls off the TB
organisms, and the TB remains inactive throughout life in most
people who are infected.
This person would have a positive
skin test, but a normal chest X-ray.
LATENT
This describes the person who has signs and
symptoms of an active infection. The person would have a
positive skin test and a positive chest X-ray.
TB DISEASE
It caused by a TB germ that
is resistant to at least isoniazid and rifampin, the two most
potent TB drugs.
MULTIDRUG RESISTANT TUBERCULOSIS (MDR-TB)
Sometimes the anti-TB drug being taken by the patient can no
longer kill the TB bacteria.
DRUG RESISTANT TB
a rare type of MDRTB that is resistant to isoniazid and rifampin, plus any
fluoroquinolone and at least one of three injectable second-line
drugs (i.e. amikacin, kanamycin, or capreomycin)
EXTENSIVELY DRUG-RESISTANT
TUBERCULOSIS (XDR- TB)
The WHO-approved standardized and
effective cure for TB
DOTS - Directly Observed Treatment, Short-course
DOTS
Directly Observed Treatment, Short-course
How many months of medication to completely treat TB?
6-8 months
Medicines for TB
(RIPE)
Rifampicin
Isoniazid
Pyrazinamide
Ethambutol
Streptomycin
How is TB transmitted?
- By air (since it is an airborne particle) when someone who has active TB sneezes, coughs, shout, or sing.
