Pertussis

Pertussis is also known as whopping cough

Lower Respiratory Tract infection Slide3

Etiology

Caused by bacterium Bordetella pertussis

Gram (-) cocci bacterium

Encapsulated immotile aerobe that do not make spores

It produces a pertussis toxin, adenylate cyclase toxin,

filamsntous hemagglutinin and hemolysinSlide4

Epidemiology

Infants and children, especially babies less

than 1 year of age

In the U.S. during 2012, 48,277 cases of

pertussis were reportedSlide5

Mode of Transmission

Direct contact or inhalation of airborne droplets

Incubation period: 7-10 days witha a range of 4-21 days Slide6

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. Slide7

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-raySlide8

Treatment

Antibiotics

Treatment after 3 weeks is unlikely to

help because the bacteria leaves the

body but the symptoms remainSlide9

Prevention

Pertussis Vaccine

Infants, children, teens, and adults.

Children should get the DTaP vaccine which protects

gainst pertussis, diphtheria, and tetanus

Teens and adults should get the Tdap vaccine

Adults should get the Td booster every ten yearsSlide10
