Overview
The primary risk factors for Pertussis involve its highly contagious nature by being within close proximity of an infected individual. Children and infants are particularly suspectible due to a greater chance of non-vaccination and a more vulnerable, less-developed immune system. Adults and adolescent risk factors are having waning immunity due to length of time from initial immunization and the lack of, or weakening, booster vaccine.
Risk Factors
The risk factors are Pertussis involve its highly contagious nature:[1]
- Coming into close proximal contact with an infected individual
- 90% of susceptible household contacts developing clinical disease following exposure to an index case[2]
- Children and infants are at the highest risk
- Lesser-developed immune system in conjunction with exposure to Pertussis pre-vaccination
- Not having received the DTaP vaccination or the TDap Booster
- Being predisposed to infection due to immunodeficient conditions [1]
