    Study Notes

    Whooping Cough Overview

    • Acute and highly communicable respiratory illness characterized by severe coughing fits, often resulting in a distinctive "whoop" sound upon inhalation.
    • Primarily affects children, although it can occur in individuals of all ages.

    Causative Agent

    • Bordetella pertussis is the responsible bacterium; it is a small, gram-negative coccobacillus.
    • Highly infectious, B. pertussis spreads mainly through respiratory droplets from infected individuals.

    Transmission

    • Transmitted from person to person, primarily through inhalation of aerosolized particles when an infected person coughs or sneezes.
    • The contagious nature emphasizes the importance of vaccination and herd immunity in controlling spread.
