Abstract
Background: Pertussis, a disease that has been well described since the Middle Ages, has a worldwide distribution and can infect all ages. It is caused by the gram-negative, pleomorphic bacillus Bordetella pertussis, which is transmitted from human to human via aerosolized droplets at close range. Descriptions such as the one-hundred day cough in Chinese and whooping cough in English, describe the severity of this disease seen in both the developed and the developing world.
