Whooping cough also called Pertussis is a very old disease, first recognised in Paris, France in AD 1578 when it caused an epidemic. It occurs all over the world but more in developing countries of Asia, Africa and the Americas.
It is most common in children under two years but exists in adults who serve as reservoir of the infection. According to the World Health Organization, about 17.9 persons were affected globally by the disease in 2003 with about 279,000 deaths; about 90 percent of these figures in developing countries.
The situation was much worse before 1950 when the vaccine against whooping cough was developed. Today all infants are expected to be vaccinated against Whooping cough as part of DPT vaccine.
Neither the infection nor vaccination gives life-long immunity.
