Basics
- Highly contagious among close contacts
- Synonyms: whooping cough, “100 day cough”
Description
- Host: humans
- Most common reservoir: adults
- Ages: all
- Distribution: worldwide
- Pattern: endemic or epidemic with outbreaks every 3 to 5 years (1)
- Seasonality: peaks late summer–autumn; can occur year-round
- Transmission: person to person via aerosolized droplets (1)
- Typical incubation period: 7 to 10 days (1)
- Effective vaccine: available
- Immunity: neither 100% nor lifelong immunity with either infection or vaccine (1)
- System(s) affected: respiratory
Epidemiology
Incidence
Etiology and Pathophysiology
- Toxin mediated
- Infectious process with predilection for ciliated respiratory epithelium
- Common organisms:
- Bordetella pertussis
- Bordetella parapertussis
Genetics
No known genetic predisposition
Risk Factors
- Exposure to a confirmed case
- Non- or underimmunized infants and children
- Premature birth
- Chronic lung disease
- Immunodeficiency (e.g., AIDS)
- Age <6 months (accounts for ~90% pediatric pertussis hospitalizations) (3)
General Prevention
- Public health measures
- Surveillance
- Outbreak management
- Care of exposed individuals
- Prevention programs
- Immunizations (4)
- Primary childhood immunization series against pertussis followed by boosters
- Maternal immunization during each pregnancy
- Adults, including health care providers in close contact with infants <1 year of age, should be immunized.
Pediatric Considerations
Strategies to reduce neonatal pertussis (1):
- Tdap with each pregnancy, ideally between 27 and 36 weeks’ gestation
- Cocooning
- Tdap recommended for all persons in close contact with infants <1 year of age
Geriatric Considerations
Older adults are at increased risk for pertussis complications due to (5):
- Age-related changes in immunity
- Comorbid medical conditions
Commonly Associated Conditions
- Apnea in infants
- Secondary bacterial pneumonia
- Sinusitis
- Seizures
- Encephalopathy
- Urinary incontinence
