Lower Respiratory Tract infection

3. Etiology Caused by bacterium Bordetella pertussis
Gram (-) cocci bacterium

6. Clinical Manifestation/Symptoms
Stage 1 (catarrahl stage) lasts 1-2 weeks consist of sneezing, low fever, and cough.
Stage 2 (paroxysmal stage) lasts 1-6 weeks consist of episodes of paroxysmal cough with characteristic whopping sound
Final stage (convalescent stage) Symptoms gradually decrease although coughing may last for several months
Diagnosis can be difficult because whooping cough shares many symptoms with the flu, cold and bronchitis.

7. Diagnostic tests Physical examination
Laboratory test which involves taking a sample of secretions (with swab) from back of the throat through the nose
Blood Tests
Chest X-ray

8. Treatment Antibiotics
Treatment after 3 weeks is unlikely to help because the bacteria leaves the body but the symptoms remain
