What is it?
Bronchitis is a respiratory disease (lower)
which mucus membranes in the lungs
bronchial passages become inflamed.
Bronch-ITIS: inflammation
in bronchial tubes
Etiology
Caused by viral infections, bacteria, or other particles hat irritate the
bronchial tubes.
There are many types of viruses and bacteria that causes bronchitis:
• H. Influenzae
• H. parainluenzae
• S. Pneumoniae
Main virus
S. Pneumoniae
• Gram positive
• Slightly pointed cocci
What is a virus?
• an infective agent
that typically
consists of a
nucleic acid
molecule in a
protein coat
Epidemiology
When does it commonly occur?
• Winter
• Western part of U.S
Why the western part?
• Because those are where it is mostly populated which causes smog and
other irritants in the air which will cause the bronchitis.
Statistics:
• Incidence (annual) of Acute Bronchitis: 4.6 per 100 (NHIS96: acute
bronchitis); 14.2 million cases annually
• Incidence Rate: approx. 1 in 21 or 4.60% or 12.5 million people in USA
Forms
There are 2 forms of bronchitis:
• Acute ( last from 1-3 weeks)
• Chronic (last 3 moths of the year to 2
years)
Acute bronchitis
• Responsible for a hacking cough and phlegm production that accompany
an upper respiratory infection. Caused by viruses from influenza.
Chronic Bronchitis
C.O.P.D. = Chronic Obstructive Pulmonary Disease is the result
• Mainly caused by smoking tobacco
58 year old male
smoker with
moderate C.O.P.D
Who?
• Smokers
• Second hand smoking
• Weakened immune system
• Elderly and infants
• GERD (gastro esophageal
• reflux disease)
• Exposure to irritants
GERD and Bronchitis
Acid reflux irritates the airways and lungs, which
affects breathing and may make people more
sensitive to outside conditions such as air
pollution, cigarette smoke, and cold air.
This is only for Acute
bronchitis
Symptoms for
Chronic and Acute
• Cough
• Production of
colored mucus
• Fatigue
• Shortness of breath
• Slight fever/ chills
• Chest discomfort
Risk Factors for
Acute and
Chronic
• Smoking
• Low resistance
• Exposure to
irritants
• Gastric reflux
Transmission
• Air borne particles
• Escalation of the flu or cold
• Physical contact with infected
surface or person
Tests and Diagnosis
• Chest x-ray
• Sputum test (test mucus)
• Pulmonary function test
Treatments
• Antibiotics (only if doctor suspects
bacterial infection)
• Cough medicine
• inhaler
Prevention
• Avoid cigarette smoking
• Get the Flu vaccine
• Wash hands wear surgical mask (if
exposed to irritants at curtain jobs)
